1   Site Preparation

Select the installation site for the SmartEdge® 100 router, considering maintenance, electrical, and ventilation requirements. In addition, consider current and future cabling requirements.

1.1   Agency Compliance Information

(1)  The TX GBIC transceiver does not comply with the Network Equipment Building Standards (NEBS) electrostatic discharge (ESD) requirement.

1.2   Electrical Specifications

Note:  

Nominal voltage is recommended to allow brief brownout and over-voltage events.

(1)  The low-voltage alarm on the chassis is raised when the input voltage drops below -33Vdc. The power monitoring circuit has a wide tolerance of -33Vdc to -38Vdc, so input voltage within this range may not raise the low-voltage alarm.

DC power connections require copper wire of a size suitable for the installation (#4 AWG for chassis ground, #12 AWG for DC power cables) in accordance with the National Electrical Code (in the United States) or applicable local jurisdiction (outside the United States) installation requirements. An external fuse panel, either a standalone unit or incorporated in a DC power supply system, or a circuit breaker panel, is required for power on and power off control for DC-powered systems.

AC power connections require a separate circuit with a 15-ampere circuit breaker. Do not connect any other equipment to a circuit to which the SmartEdge 100 chassis is connected.

(1)  Inrush current occurs only during power on. Unless noted, maximum duration is 3 µs.

(1)  Inrush current occurs only during power on.

1.3   Environmental Requirements

The installation area for the SmartEdge 100 hardware must allow a minimum of 20.0 inches (50.8 cm) at the front of the chassis (for maintenance and ventilation).

Because the cooling air exits at the rear of the chassis, this area must not be blocked; nor must exhaust air from other equipment blow into the front of the SmartEdge 100 chassis.

(1)  Long term refers to normal operating conditions.

(2)  Short term refers to a period of time not more than 96 consecutive hours and a total of not more than 15 days in one year (360 hours in any given year, but no more than 15 occurrences during that year).

1.4   Physical Specifications

Note:  

Chassis depth dimension does not include front cable management brackets.

1.5   Select the Rack

The SmartEdge 100 chassis requires two rack units (RUs). An RU is 1.75 inches (4.5 cm). You can mount the SmartEdge 100 chassis in a standard 19- or 23-inch rack. If you use a standard 45 RU rack, you can install up to 22 SmartEdge 100 chassis in a single rack for maximum density. If density is not a consideration, you can mount the chassis in a standard 42 RU rack.

1.6   Equipment and Personal Safety Warnings

1.7   DC Power Source Warnings

1.8   Access During the Initial Startup and Reload Operations

During the initial startup, only the Craft port (also referred to as the console port) is operable until you have configured the Ethernet port (also referred to as the management port). During a reload operation, the management port is disabled until the initial stage of the reload is complete; all messages displayed during the reload are sent to the Craft port.

You access the SmartEdge 100 router with a console terminal connected to the Craft port, either directly or through a terminal server.

1.9   Access During Normal Operations

After you have configured the management port, you can use one or more of the following options to provide management access:

• A local management workstation, using a connection to the Ethernet management port on the chassis front panel.
• A remote management workstation, using a routed or bridged connection to the Ethernet management port on the chassis front panel.
• A local console terminal with a direct connection to the Craft port on the chassis front panel.
• A remote console terminal with a connection to the Craft port on the chassis front panel, using a terminal server.

For redundancy, Ericsson recommends using two different methods (for example, a remote workstation and a remote console terminal with a connection to a terminal server).

1.10   Management Access Options

Note:  

The Craft port does not support a modem connection.

1.11   Gathering Cables and Tools

In addition to the equipment shipped with the SmartEdge 100 router and the equipment required for installation, you require cables for the following connections:

• MIC and native port cables:

  	Warning!
  The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 5) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

When you have finished installing the hardware, you are ready to check the operational status.

The term, GE, applies to any GE native port or MIC that supports a port speed of 1 Gbps or greater; unless explicitly stated, the speed of any GE port is 1 Gbps.

2.1   Install Chassis Mounting Brackets

Two pairs of chassis mounting brackets are shipped with the chassis. Each bracket requires four 10-32 x 0.25-inch screws, which are included with the mounting brackets. One pair of brackets is for mounting the chassis in a 23-inch rack; the other pair of brackets is for mounting in a 19-inch rack.

Note:  

If you are mounting the chassis in a 23-inch rack or if you are mounting it in a 19-inch rack in the mid-mount position, remove the 19-inch brackets from the chassis.

To install either type of bracket:

1. Position a mounting bracket against one side of the chassis, lining up the screw holes in the bracket with the screw holes in the side of the chassis, in accordance with the mounting option you have selected.
2. Using a Phillips screwdriver, attach the bracket to the chassis with the screws provided with the mounting bracket; tighten each screw to a maximum torque of 15.0 inch-lbs (1.7 Newton-meters).
3. Repeat Step 1 and Step 2 to attach the second bracket to the other side of the chassis.

2.2   Install Chassis

To install the SmartEdge 100 chassis in the rack, you need four 12-24 or equivalent screws:

1. With another installation engineer, lift the chassis to the position selected in the rack.
2. Line up the screw holes in the mounting brackets with the screw holes in the rack.
3. With one engineer holding the chassis in place, use a Phillips screwdriver to secure the chassis to the rack with four 12-24 or equivalent screws; tighten each screw to a maximum torque of 30.0 inch-lbs (3.4 Newton-meters).

2.3   Install Cable Management Brackets

The SmartEdge 100 router is shipped with a pair of cable management brackets for the front of the chassis. When installed, each bracket accommodates both fiber-optic and non-fiber cables.

To install a bracket, align it with two unused screw holes in the attached flange; using a Phillips screwdriver, secure it with two 6-32 x 0.25-inch flat-head screws provided with each bracket. Then tighten each screw to a maximum torque of 9.6 inch-lbs (1.1 Newton-meters).

2.4   Connect Chassis Ground Cable

The back panel of the SmartEdge 100 chassis has a pair of M5 screws, which are used to attach a ground cable, at the upper left corner of the chassis rear panel.

Note:  

If installed in a Central Office, the ground cable size must be minimum 8 AWG. If the connector cannot handle the current, the ground cable must be the same AWG as the power conductors.

The SmartEdge 100 chassis is suitable for a Common Bonding Network (CBN).

The ground cable must be of a size suitable for the installation (#4 AWG standard copper), and must be installed in accordance with the National Electrical Code (in the United States), or the applicable local jurisdiction (outside the United States) installation requirements.

To connect the chassis ground cable:

1. Using a crimping tool, attach a two-hole lug to one end of the ground cable.

   Note:  

   Bare connectors and all grounding surfaces must be brought to a bright finish and coated with an antioxidant before crimp connections are made.

   
   
2. Using a Phillips screwdriver, remove the pair of M5 screws.
3. Place the two-hole lug over the screw holes and insert the screws in the screw holes.
4. Using the Phillips screwdriver, tighten the screws to a maximum torque of 15.0 inch-lbs (1.7 Newton-meters).
5. Connect the other end of the cable to an appropriate ground point.

   Note:  

   To properly secure power and ground connections, use star washers for anti-rotation and thread-forming screws with paint-piercing washers, where applicable.

   
   

   	Warning!
   Risk of electrical shock. The system uses DC power sources, which can cause severe injury. The DC power sources must be installed only in restricted access areas (dedicated equipment rooms, equipment closets, or the like) in accordance with Articles 110-17, 110-26, and 110-27 of the National Electric Code, ANSI/NFPA 70. Connect the chassis to a –48 VDC source that is reliably connected to earth. The SmartEdge 100 chassis is suitable for installation in Network Telecommunication Facilities.

   	Warning!
   Risk of electrical shock. A readily accessible disconnect device, such as a fuse in a fuse panel, must be provided in the fixed wiring for each DC power source. It must be suitable for the rated voltage and current specified. Because a system is fully powered on after all power connections are made, it can cause shock if a power cable is disconnected from the chassis.

   	Warning!
   Risk of electrical shock. Safe operation of this equipment requires connection to a ground point. To prevent possible injury from voltages on the telecommunications network, disconnect all telecommunications network lines before disconnecting the unit from the ground point.

   	Warning!
   Risk of electrical shock. This equipment uses –48 VDC power, which can cause shock if inadequate power sources are connected to it. Verify that the power sources for the SmartEdge router meet the power specifications and ensure that DC power cables meet the specifications before connecting the power cables.

   	Warning!
   Risk of electrical shock. Improper grounding can result in an electrical shock. This equipment must be connected to a protective ground in accordance with the instructions provided in this guide.

   	Caution!
   Risk of equipment damage. A DC-powered system uses –48 VDC power, is powered from a fuse panel, and can be damaged by overloaded circuits. Ensure that the fuses in the external fuse panel are suitably rated for the installation in accordance with the National Electrical Code (in the United States) or applicable local jurisdiction (outside the United States) installation requirements.

2.5   Install DC Power Cables

Note:  

Use only copper American wire gauge (AWG) cables for power and ground connections.

The SmartEdge 100 chassis has connectors for A-side and B-side power cables for power redundancy; these connectors are located on the rear panel of the chassis. The A- and B-side power cables are connected to separate A-side and B-side connectors on the external fuse panel or circuit breaker panel. The chassis requires AWG #12 standard copper wire for the DC power cables.

The SmartEdge 100 Battery Return (BR) is intended to be an Isolated DC Return (DC-I).

To install the DC power cables:

1. Ensure that the circuit breakers are set to the off position, which is marked by a stamped “0” on the chassis rear panel.
2. Attach a DC plug to a pair of DC power cables:
   1. Pull the DC power plug from the A-side connector at the rear of the chassis to remove it.
   2. Using a slotted screwdriver, loosen the recessed screws in the top of the DC plug and insert the –48 VDC cable in the minus (–) opening and the return cable in the plus (+) opening.
   3. Tighten the screws to a maximum torque of 0.5 inch-lbs (4.4 Newton-meters)
3. If you are installing redundant DC power sources, attach the second pair of DC power cables to a second plug.
4. Insert the A-side and B-side plugs in the connectors on the rear panel of the chassis, so that they are oriented 180° with respect to each other, as shown in Figure 8. The connectors are polarized so that you cannot insert them incorrectly.
5. Secure the cables to the circuit-breaker shields as shown in Figure 8.

2.6   Install AC Power Cord

To install the AC power cord:

1. Ensure that the circuit breaker is set to the off position, which is marked by a stamped “0” on the chassis rear panel.
2. Insert the AC power cord in the connector.
3. Secure the AC power cord to the circuit-breaker shield.
4. Plug the other end of the AC power cord to a building outlet that provides a 15A circuit.

2.7   Install MICs

MICs for the SmartEdge 100 router are installed in the chassis when it is shipped.

2.8   Install CF Card

There is an external slot on the chassis front panel in which you can install a Type I CF card. If a CF card is shipped with the chassis, it is installed in the external slot and no installation procedure is needed.

2.9   Install the Optical Transceivers

Optical ports require a small form-factor pluggable (SFP) transceiver in each port. These ports include native ports when configured as optical ports and ports on the ATM, optical GE, and optical FE MICs.

To install an optical transceiver of any type:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located in the lower right corner of the air intake panel on the front of the chassis.
2. Ensure that the SFP latching mechanism is closed.
3. With the transceiver aligned with the connector in the chassis front panel or MIC front panel (as shown in Figure 10), slide the transceiver into the opening for the port until the rear connector is seated and the locking mechanism snaps into place. In Figure 10, the SFP is aligned with an upper port, either native or MIC; to install the SFP in a lower port, rotate the SFP 180°.
4. Leave the dust cover on until you are ready to insert the fiber-optic cables.

2.10   Connections for Management Access

Connecting a console terminal or management workstation to the SmartEdge 100 router is often a two-stage process. Initially the console terminal is connected to the Craft port (also referred to as the console port) to configure the Ethernet port (also referred to as the management port); configuring the management port and modifying the configuration of the console port is described in SmartEdge OS documentation. When the configuration is complete, you might need to alter the connections for normal operations.

2.11   Management Workstation

A management workstation is connected to the SmartEdge 100 router using the upper Ethernet port on the front panel. This type of connection provides access to the SmartEdge OS command-line interface (CLI) after you have configured the port.

Neither type of connection is suitable during a reload operation, because the Ethernet management port is disabled until the reload is complete.

2.12   Local or Remote Console Terminal

A local or remote console terminal is connected to the SmartEdge 100 router using the Craft port on the front panel. This type of connection provides access to the SmartEdge OS CLI, either directly or through a terminal server. This port is always available; all system messages are directed to this port during a reload operation.

Note:  

The Craft port does not support a modem connection.

2.13   Connect and Route the Cables at the Front of the Chassis

All MIC cables are connected to the front panels of the MICs.

To connect and route the cables at the front of the chassis:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; an ESD convenience jack is located in the lower right corner of the air intake panel on the front of the chassis.
2. Connect and route the management access cables, depending on the type of management access you have selected, and the cables for the native ports; see Figure 11 for connecting a management workstation and Figure 12 for connecting a local or remote console:
   1. Thread the system ends of the system management and native port cables through the cable management bracket at the left side of the chassis.
   2. Insert each cable in the appropriate connector on the front panel.
   3. Tie-wrap the cables to form a bundle, and then tie each bundle to the cable bracket.
3. To connect and route the cables for the MIC ports:
   1. Thread the system ends of the MIC cables through the cable management bracket at the right side of the chassis.
   2. Insert each cable in the appropriate connector on the MIC front panel.
   3. Tie-wrap the cables from each MIC to form a bundle, and then tie each bundle to the cable bracket.

2.14   Connect the Equipment and Network Ends of the Cables

To connect the equipment and network ends of the cables:

1. Connect the MIC cables to their networks.
2. Ensure that the management access equipment is configured properly.
3. Connect the management access cables to the equipment or their networks.

2.15   Powering On and Powering Off the System

You power on the SmartEdge 100 router by moving the circuit breaker on the chassis rear panel to the on position, which is marked by a stamped “1” on the chassis rear panel. You power it off by moving the circuit breaker to the off position, which is marked by a stamped “0”.

The AC version of the SmartEdge 100 chassis has a single circuit breaker above the AC power cord connector; see Figure 14. The DC version of the chassis has dual circuit breakers with the A-side circuit breaker above the A-side connector and the B-side circuit breaker below the B-side connector; see Figure 15.

The circuit breaker provides protection against power surges and drops; if a power surge or drop occurs that is outside the range of power supported by the system, the circuit breaker shuts down the system.

During the power-on sequence for a SmartEdge 100 router, the MICs are held in low-power mode until after the controller carrier card is initialized. The SmartEdge OS then performs a power capacity check to ensure that the installed MICs have enough power to be completely operational. Each installed MIC is compared with the MIC configuration for that slot. If they are the same, the MIC is initialized. If the installed and configured MIC types are different, the SmartEdge OS leaves the MIC in low-power mode.

3   Hardware Control and Troubleshooting

The operating system command-line interface (CLI) includes commands that display hardware configuration and status information, allow hardware troubleshooting, and provide hardware control and recovery.

The mode in which you enter a command is as follows:

• Enter show commands in any mode.
• Enter clear and reload commands in exec mode.
• Enter the card command and the port command for any type of port in global configuration mode.
• Enter the loopback and shutdown command in port configuration mode.

3.1   Hardware Status

The CLI commands listed in Table 22 display status information, such as power, temperature, ports, and alarms for the fan tray and individual cards and ports. Required characters and keywords are shown in bold; arguments for which you must supply a value are shown in italics. You can enter show commands in any mode.

For descriptions of the output for any CLI command, see Command List Reference [4].

3.2   CLI Commands for Hardware Control

(1)  Because the SmartEdge OS software synchronizes all write operations to the file system, you can power down the system without issuing the shutdown command.

3.3   CLI Commands for Hardware Troubleshooting

Required characters and keywords are shown in bold; arguments for which you must supply a value are shown in italics.

(1)  The internal keyword for all FE and GE ports, causes all transmitted traffic to be looped back and not sent to the remote site; instead, the remote site receives a loss of signal (LOS). For a port on a second-generation ATM OC MIC, the port software injects an alarm indication signal-line (AIS-L) and then resumes transmitting traffic.

3.4   Values for CLI Input Arguments

3.10   Determine the Status of System Equipment

The change in state of the SWAP LED is as follows:

• When a CF card is installed and you open the door, the SWAP LED state changes from “Off” to “Blinking” until the unmounting process is complete. It then changes state to “On” to indicate that you can safely remove the card.
• If the system cannot unmount the file system on the card, the SWAP LED changes back to “Off” (while the door is still open) and the system displays an error message on the console.
• If you close the door without inserting a CF card in the slot, the LED remains “On”.
• If you insert a formatted CF card in the slot and close the door, the LED changes from “On” to “Blinking” until the mounting process is complete. It then changes state to “Off”.
• If the system is unable to mount the file system on the CF card (for example, because it is unformatted or the file system is damaged), the LED changes from “On” to “Blinking” and then, because the CF card cannot be mounted, changes to “On” and the system displays an error message on the console.

3.11   Determine the Status of ATM MIC Ports

The ATM MIC provides three equipment LEDs to indicate the current status of the MIC and three facility LEDs to indicate the status of each port.

(1)  A failure can be total, partial, or forced. Failure on any part of the MIC, including failure of any of its ports, results in the FAIL LED being illuminated.

(2)  Protection for cards and ports is dependent on the release of the SmartEdge OS.

3.12   Determine Status of Ethernet Management and Copper FE MIC Ports

3.13   Determine Status of Native, Optical FE, Optical GE, and Copper GE MIC Ports

3.14   Results from Power-On Diagnostics

Power-on diagnostics (POD) verify the correct operation of the carrier card and each installed MIC during a power-on or reload sequence of the SmartEdge 100 router. These tests also run whenever a MIC is installed in a running system. The POD for each component consist of a series of tests, each of which can indicate a component failure.

Note:  

A description of each test is beyond the scope of this guide.

During each test, the POD display results and status; if an error occurs during the testing, the STAT LED is illuminated; but the error does not stop the loading of the SmartEdge OS.

To display results from the POD, enter one of the following commands in any mode:

show diag pod component

show diag pod component detail

The detail keyword allows you to determine which test the component has failed.

In general, if a component fails to pass its POD, you need to replace it or make arrangements for its replacement. Contact your local technical support representative for more information about the results of a failed test.

The POD are enabled, by default, in the SmartEdge OS; if the POD have been disabled, you can enable them with the following command in global configuration mode:

diag pod

3.15   Troubleshoot Using System Equipment LEDs

To troubleshoot alarm conditions for the system, see Troubleshoot with System Power and Alarm LEDs or consult your local technical representative for information.

3.16   Troubleshoot Using Port LEDs

The facility LEDs for each port on the system display the current port status. For definitions of facility LEDs, see the appropriate section:

• Determine the Status of ATM MIC Ports
• Determine Status of Ethernet Management and Copper FE MIC Ports
• Determine Status of Native, Optical FE, Optical GE, and Copper GE MIC Ports

If you are experiencing hardware problems, check the LEDs to determine the possible problem and solution.

3.17   Troubleshooting with On-Demand Diagnostics

You can use on-demand diagnostics to troubleshoot the controller and I/O carrier cards and MICs. On-demand diagnostic (ODD) tests can isolate a fault up to the field replaceable unit (FRU). Four levels of tests are supported.

Note:  

Any MIC, if it is installed, is tested as part of the testing of the I/O carrier card.

The following guidelines apply to the on-demand testing of carrier cards and MICs:

• The cards that you can test depends on the release of the software. In the current release, you can test the following cards:
  • Controller carrier card and I/O carrier card
  • Ethernet management port, native ports, and MIC ports
• Before you can test either carrier card and any MIC, you must take the system out of service.

A session log stores the latest results for each card in main memory and also on the compact-flash card for low-level software; a history file that stores the results for previous sessions (100 sessions) is also stored on that compact-flash card.

You can display partial test results while the tests are in progress; a notification message is displayed when the session is complete. To view test results, enter the show diag on-demand command (in any mode) at any time. You can display the latest results for the carrier card, the Ethernet management port, the native ports, or MIC ports from the log, or the results for one or more sessions from the history file.

Note:  

If you are connected to the system using the Ethernet management port, you must enter the terminal monitor command (in exec mode) before you start the test session so that the system displays the completion message. For more information about the terminal monitor command, see Command List Reference [4].

3.18   Initiating ODD Session

Specify slot 1 to test the controller carrier card; specify slot 2 to test the I/O carrier card. Specify slot 1 to test the Ethernet management port; specify slot 2 to test any of the native or MIC ports.

To run ODD tests for the controller carrier card in a SmartEdge 100 chassis, perform the following tasks and enter the command in exec mode. No preparation is needed when testing the controller carrier card.

To prepare the I/O carrier card for an ODD session.

To run ODD tests for the I/O carrier card for all native and MIC ports, including the Ethernet management port, in a SmartEdge 100 chassis, perform the following tasks and enter all commands in exec mode.

Note:  

To terminate an ODD session, enter the no form of the diag on-demand command.

Table 57 lists the affect on these indicators by the clear diag command (in exec mode), a reload of the system, the replacement, reload, change of state of the card, or an ODD session that the card successfully passed.

The following guidelines apply to the data and operations listed in Table 57

• You can display alarm and ODD status using the show hardware command (in any mode).
• You can clear the ODD log or history using the clear diag command (in exec mode).
• Replacing a MIC or reloading the system causes the power-on diagnostics (POD) to run; the LED status reflects the results of the POD tests. You cannot reload a MIC if it is in the ODD state.

3.19   Returning I/O Carrier Card to In-Service State

After testing the I/O carrier card, you must return the card to the in-service state. To return the card to the in-service state, perform the tasks described in Table 58; you must enter the no form of the on-demand diagnostic and shutdown commands.

Note:  

To reload the I/O carrier card or MIC, using the reload card or reload mic command (in exec mode), respectively, you must first remove the card from the ODD state.

3.20   Administering Results from an ODD Session

(1)  Configuration is lost if not saved before running ODD.

(2)  No MICs are installed in the MIC slots.

(3)  LEDs are unaffected except for a brief blink during port initialization if they were on before ODD.

3.21   Clearing Results from an ODD Session

To clear or display the results from one or more on-demand diagnostic sessions, perform one or more of the following tasks and enter the clear diag command in exec mode. Enter the show diag command, which can display results for up to 20 sessions from the history log, in any mode.

3.22   ODD Examples

To initiate a session on the controller carrier card and display results:

[local]Redback#diag on-demand card 1 level 2 loop 4
[local]Redback#show diag on-demand card 1

The following example shows how to initiate a session on the Ethernet card in slot 3, display results, and return the card to the in-service state:

!Place the I/O carrier card in ODD state
[local]Redback#configure
[local]Redback(config)#card carrier 2
[local]Redback(config-card)#shutdown
[local]Redback(config-card)#on-demand-diagnostic
[local]Redback(config-card)#end

!Run an ODD session
[local]Redback#diag on-demand card 2 level 3 loop 5
!Display results
[local]Redback#show diag on-demand card 2 detail

!Return the I/O carrier card to the in-service state
[local]Redback#configure
[local]Redback(config)#card carrier 2
[local]Redback(config-card)#no on-demand-diagnostic
[local]Redback(config-card)#no shutdown
[local]Redback(config-card)#end

The following example shows the output after tests have been run on the I/O carrier card:

[local]Redback#show diag on-demand card 2 detail

4   Servicing the Hardware

This chapter describes servicing procedures for the SmartEdge 100 router, including servicing media interface cards (MICs) and transceivers, inserting and removing compact-flash (CF) cards, and how to obtain assistance. The only tool needed to perform the procedures in this chapter is a #1 Phillips screwdriver.

After you replace a line card or change its physical configuration, you must enter SmartEdge OS commands from the command-line interface (CLI) to restore the card to normal operations.

The SmartEdge 100 chassis has an EEPROM that supplies the medium access control (MAC) address for the chassis. If it should ever be necessary to replace the EEPROM, contact your local technical representative for directions.

4.1   Inserting and Extracting a MIC

The term GE applies to any GE native port or MIC that supports a port speed of 1 Gbps or greater; unless explicitly stated, the speed of any GE port is 1 Gbps.

After you replace a MIC or change its physical configuration, you must enter SmartEdge OS commands from the command-line interface (CLI) to restore the MIC ports to normal operations.

The design of the SmartEdge 100 router allows you to install and replace all MICs without powering off the system.

4.1.1   Insert a MIC

To insert a MIC:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the front of the chassis.
2. Align the MIC with the notched guides and then carefully slide the MIC into the slot.
3. Push the MIC until it is flush with the front panel.
4. Tighten the captive screws alternately.
5. Tighten the captive screws, to a maximum torque of 4.0 inch-lbs (0.5 Newton-meters).

4.1.2   Extract a MIC

To extract a MIC:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the front of the chassis.
2. Using a Phillips screwdriver, loosen the captive screws on the front panel of the MIC being removed.
3. Holding the MIC handle and keeping it perpendicular to the slot, pull gently on the MIC to disengage it from the carrier card.
4. Keeping the MIC horizontally level, carefully slide the MIC out of the chassis, and place it in an antistatic bag.

4.2   Insert a Transceiver

To insert a transceiver of any type:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the front of the chassis.
2. Ensure that the latching mechanism is closed.
3. With the transceiver connectors as shown in Figure 22, slide the transceiver into the opening for the port until the rear connector is seated and the locking mechanism snaps into place.
4. Remove the dust cover if you are installing an optical transceiver.

4.3   Extract a Transceiver

To extract a transceiver of any type:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the front of the chassis.
2. Release the latching mechanism:
   1. If the transceiver has a wire handle, unlatch it, and rotate it 90° to 180°.
   2. If the transceiver has latching tabs, squeeze and hold the tabs.
3. Withdraw the transceiver from its port and insert a dust cover over the optical connectors.

4.4   Remove a CF Card

To remove a CF card:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the chassis front panel.
2. Open the door that covers the CF Type 1 slot until it “snaps” open. This action begins unmounting the file system on the CF card. The SWAP LED blinks (blue) during the unmounting process.
3. Wait until the SWAP LED is on. It is now safe to remove the CF card.

   If for some reason, the system cannot successfully unmount the file system on the CF card, the SWAP LED stops blinking and changes back to “Off”. You must enter the unmount command (in exec mode) to unmount the file system on the card. For more information about the unmount command, see Command List Reference [4].

4. Press the ejection button that is inside the CF slot (see Figure 23) twice (first to cause the button to protrude from within its recess and second to disengage the CF card from its carrier card connectors.
5. Grasp the CF card and pull gently and slowly until it is fully outside the slot.
6. Close the door so that it snaps shut; the SWAP LED remains off.

4.5   Install CF Cards

To install a CF card:

1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the chassis front panel.
2. If a CF card is currently installed, remove the card using the procedure described in the “ Remove a CF Card” section.
3. Hold the CF card to be installed so that its pin-hole side faces the slot in the front panel and horizontally align it as close to the bottom edge of the slot as possible and perpendicular to it; see Figure 24.
4. Slowly insert the card in the slot; keep the card perpendicular to the front panel. If the card does not engage the carrier card connectors with approximately 0.50 inches (1.27 cm) of the card outside the slot, do not continue. Remove the card and repeat this step.

   Note:  

   The CF card is polarized; if the card does not engage the connectors, rotate the card 180° and try again.

   
   
5. Close the door until it snaps shut. The system automatically recognizes the CF card and begins to mount it. The SWAP LED begins to blink.
6. After the SWAP LED stops blinking (is off), you can begin using it to store data.

   If for some reason, the system cannot successfully mount the file system on the CF card (for example, the file system is damaged or the card is unformatted), the SWAP LED stops blinking and changes back to “Off” and the system displays an error message on the console. You must enter the format media-device command (in exec mode) to format the CF card and the mount command (in exec mode) to mount it. For more information about the format media-device and mount commands, see Command List Reference [4].

4.6   Add MIC Cards

To add a MIC to an operational system:

1. Prepare for installation:
   1. Ensure that the system is fully operational (you have the CLI prompt on the console).
   2. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located in the lower right corner of the air intake panel on the front of the chassis.
2. Loosen the captive screws and remove the MIC slot cover that is installed in the slot for the new MIC.
3. Install the MIC; see the generic procedure in the Insert a MIC.

   	Caution!
   Risk of data loss. Install only the transceivers purchased from Ericsson. You can corrupt the system if you attempt to install SFP transceivers that are not purchased from Ericsson, because these items have not been tested with the SmartEdge router.

4. If the MIC requires transceivers, install the transceivers, using the procedure in the “ Insert a Transceiver” section.
5. After the transceivers have been installed, verify the operational status.
6. If you have installed transceivers, remove the dust cover from the connectors.
7. Connect and route the cables.

   	Caution!
   Risk of damage to fiber-optic cables. Never step on a fiber-optic cable or twist one when connecting it to or disconnecting it from a port.

4.7   Replace MIC Cards

To remove an existing MIC and replace it with a new MIC:

1. Ensure that you have the CLI prompt on the console.
2. Prepare for replacement:
   1. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located on the front panel of the chassis.
   2. Label and disconnect any cables from the front of the MIC being removed.
   3. If the MIC has transceivers installed, install a dust cover over each SFP connector.

      	Caution!
      Risk of damage to fiber-optic cables.Never step on a fiber-optic cable or twist one when connecting it to or disconnecting it from a port.

3. Remove the current MIC; see the generic procedure in Extract a MIC.
4. Install the new MIC; see the generic procedure in Insert a MIC.
5. If you are replacing a MIC with the same type of MIC, remove the transceivers from the current MIC and insert them in the ports on the new MIC, using the procedures in the “ Extract a Transceiver” and “ Insert a Transceiver” sections.
6. Check the LEDs on the new MIC to ensure proper operational status.
7. Remove the dust covers from the connectors.
8. If the MIC is the same type, reconnect the cables you previously disconnected; otherwise connect and route the cables for the ports in the new MIC.
9. Use the SmartEdge OS CLI software to restore the MIC to normal operations.

4.8   Replace Transceivers

Transceivers are hot-swappable; you can replace any transceiver without removing the MIC. However, you must shut down the port before performing the replacement procedure.

To replace a transceiver:

1. Prepare for replacement:
   1. From the console terminal or the management workstation (SmartEdge OS CLI software), shut down all activity on the port with the transceiver you want to replace. For commands to shut down the port, see Command List Reference [4].
   2. Put on an antistatic wrist strap and attach it to an appropriately grounded surface. Do not attach the wrist strap to a painted surface; there is an ESD convenience jack located in the lower right corner of the air intake panel on the front of the chassis.
   3. Label and disconnect any cables attached to the transceiver you want to replace.
   4. Install a dust cover over the SFP connectors.

      	Caution!
      Risk of damage to fiber-optic cables. Never step on a fiber-optic cable or twist one when connecting it to or disconnecting it from a port.

2. Remove the current transceiver, using the procedure in the “ Extract a Transceiver” section.
3. Install the new transceiver, using the procedure in the “ Insert a Transceiver” section.
4. If the transceiver is the same type as the one you have replaced, reconnect the cables you previously disconnected; otherwise connect and route the cables for this transceiver.
5. Use the SmartEdge OS CLI software to restore the port to normal operations.

4.9   Replace SmartEdge 100 Chassis

Because you cannot open the chassis, certain equipment failures require that you replace the chassis. For example, fans within the SmartEdge 100 chassis are not replaceable.

Although you cannot replace a component, such as a fan, within the chassis, you can perform the following tasks to reduce the risk of damage to your system:

• Notify your local technical representative about the failure.
• If the system reports a minor alarm condition (the ALRM LED is illuminated and is yellow), such as a single fan failure, alleviate any environmental condition that could cause a second failure, such as increasing the cooling at the site or ensuring that the flow of cooling air and the exhaust air from chassis is not blocked.
• If the system reports a major alarm condition (the ALRM LED is illuminated and is red), such as a multiple fan failure, replace the chassis.

To replace the chassis:

1. If you have a second SmartEdge 100 router at your site and the SmartEdge 100 router with the failure is still operating:
   1. Reroute the traffic to the second router.
   2. Power off the SmartEdge 100 router.
2. Install a replacement SmartEdge 100 router.
3. Remove the MICs, together with their cables and transceivers, from the original SmartEdge 100 router and install them in the replacement router. See Replace MIC Cards.
4. Remove the CF card, if any, from the SmartEdge 100 router and install it in the replacement router. See the “ Remove a CF Card” section.
5. Power on the replacement SmartEdge 100 router; if necessary, update its software configuration to match that on the original SmartEdge 100 router.
6. Reroute the traffic from the SmartEdge 100 router to which you had routed it, to the replacement SmartEdge 100 router.
7. Return the original SmartEdge 100 chassis to your local technical representative for repair.

4.10   Clean Optical Connectors

Clean fiber-optic components are a requirement for quality connections between fiber-optic equipment. Cleaning the fiber-optic equipment is one of the most basic and important procedures for maintaining MICs with fiber-optic connectors. Ericsson produced Inspection And Cleaning Of Optical ConnectorsReference [7] to provide detailed and comprehensive procedures for your use.

5   System Description

The SmartEdge 100 router is a carrier-class product with an architecture that supports packetized traffic. The SmartEdge 100 router can be used as an edge aggregation router and simultaneously as a broadband remote-access server (BRAS) to directly connect customers to the network. It supports a variety of interfaces and services, such as routing protocols, quality of service (QoS), and inbound and outbound access control lists (ACLs). New services can easily be added with software upgrades.

The SmartEdge 100 router can also be used in the metropolitan core to aggregate traffic from other routers into the long-haul transit core. The SmartEdge 100 router supports a wide variety of interfaces, such as Asynchronous Transfer Mode (ATM), Ethernet 10Base-T, 100Base-TX, 100Base-FX, 1000Base-FX, and 1000Base-T.

The SmartEdge 100 chassis is a rack-mountable unit that includes a single carrier card mounted within it. At the rear of the chassis are five fans for forced-air cooling. A single fan failure does not impact the operation of the system. Air intake is at the front of the chassis and air exhaust at the rear. For this reason, these areas must not be blocked by other equipment.

Two versions of the SmartEdge 100 chassis support either AC or DC power sources. The DC version has connectors for redundant power sources with a separate circuit breaker for each DC source. Because the chassis is fully powered from a single DC source, installing dual DC sources is not required. The power connectors for either the AC or DC power sources are located at the rear of the chassis.

The carrier card implements the functions of a controller card (referred to as the controller carrier card) and the functions of a line card (referred to as the I/O carrier card). The connectors and LEDs for monitoring all functions and components on the carrier card are on the chassis front panel.

The SmartEdge 100 chassis is designed for mounting in a standard 19- or 23-inch rack; it can also be placed in a desktop environment. Cable management brackets are attached to the left and right sides at the front of the chassis. All maintenance functions are performed at the front of the chassis. An electrostatic discharge (ESD) jack is located on the chassis front panel.

5.1   Controller Carrier Card Functions and Components

The controller carrier card manages the system; it is responsible for the packet routing protocols, the SmartEdge OS command-line interface (CLI), and communications with a network management system running the NetOp Element Management System (EMS) software. The controller card also loads all configuration information necessary for the line cards.

Table 61 lists the controller carrier card features.

(1)  The CRAFT port supports a direct or terminal server connection only.

(2)  Support for 1 Gbps depends on the SmartEdge OS release.

A second internal-storage device is also installed on the controller carrier card for low-level software.

5.1.1   Processors

The controller carrier card has two processors: one runs low-level software, including device drivers and equipment management software, and the other runs the routing and broadband remote access server (BRAS) software.

5.1.2   Main Memory

Synchronous Dynamic Random Access Memory (SDRAM) is used by the SmartEdge OS shared databases that are accessed by the I/O carrier card, native ports, and MICs.

5.1.3   NVRAM with Battery

The controller carrier card includes 512 KB of NVRAM, which stores the current state of the system; because it is not affected by power failures or system shutdown, the system can restore operations when power is restored or the system is restarted. Support for NVRAM is dependent on the release of the SmartEdge OS.

5.1.4   System Clock

The internal clock on the controller carrier card is a local free-running oscillator at ±50.0 ppm. The system clock refers to the clock that performs system hardware timing functions; for the SmartEdge 100 router, the system clock source is always the internal clock.

The real-time clock (RTC) on the controller carrier card is initialized before the system is shipped. The clock is not affected by power failures, system shutdown, or reload.

The source for the transmit clock for the native ports or the ports on an Ethernet MIC is always the system clock. For the ATM OC MIC, the transmit clock for a port is its onboard clock (the default), a local free-running oscillator at ±25.0 ppm. However, you can configure the transmit clock for a port to be the receive clock derived from an incoming signal to the port.

The time-of-day clock (TDC) for a SmartEdge router is implemented in software. When the system is powered on, the RTC sets the TDC; otherwise, the TDC is undefined until it is configured and set using the SmartEdge OS. The TDC can be maintained by synchronization with a Network Time Protocol (NTP) server. Periodically, the SmartEdge OS updates the RTC based on the current value of the TDC.

5.1.5   Internal Storage for SmartEdge OS files

The controller carrier card has two internal-storage devices (Type I), one of which is used to store SmartEdge OS images and files. (The other internal-storage device is used to store low-level system software.)

SmartEdge OS storage is organized into three partitions: p0, p1, and /flash. The p0 and p1 partitions each store a system image and its files; the memory on the controller carrier card can be loaded from either partition. The third partition, /flash, stores SmartEdge OS configuration files and other system- and user-created data files.

5.1.6   Optional External Storage Device

The controller carrier card has an external slot on the front panel in which you can install a Type I CF card. When installed, this device is used to capture crash dumps and provide an alternate source for loading SmartEdge OS software, when downloading the software over the network is not possible.

5.1.7   Ports for System Management Access

The CRAFT port has a DB-9 connector that provides an RS-232 connection to a local console terminal or a terminal server. The CRAFT port provides the access to the SmartEdge OS CLI for configuring and monitoring tasks.

Two 10/100/1000 Ethernet ports each have an RJ-45 connector. The upper port provides a connection to an Ethernet device, such as a switch or hub, which allows access to the SmartEdge OS CLI from either a local or remote management workstation for configuring and monitoring tasks. The system can also communicate with a remote workstation that is running the NetOp EMS software.

Note:  

The upper port is disabled in this release; support for 1 Gbps speed of the lower port is dependent on the release of the SmartEdge OS.

5.1.8   Monitoring Temperature and Voltage

Temperature is monitored at various locations within the chassis; an over-temperature interrupt signals the SmartEdge OS when the temperature rises above or falls below safe operating conditions. Voltages are also monitored and reported to the SmartEdge OS. Administrators can display both temperature and voltage data using commands in the SmartEdge OS CLI. Three levels of temperature conditions are reported: service-affecting, abnormal, and normal.

5.2   I/O Carrier Card

The I/O carrier card is a logical subdivision of the carrier card within the chassis and implements the features and functions of a line card. Like the line cards, the I/O carrier card includes dual-packet processing ASICs, Version 2 (PPA2s). These PPA2s, one for ingress traffic and one for egress traffic, process all data passing through the SmartEdge 100 router, off-loading the processors on the controller carrier card. Each PPA2 has1 GB of memory.

Unlike previous line cards, the I/O carrier card supports both fixed and removable ports with multiple speeds:

• Ports 1 and 2 are fixed; they are referred to as native ports and have their port connectors on the chassis front panel. Both ports independently support either a copper or optical connection and run at 1 Gbps.
• Ports 3 to 26 are implemented on a pair of removable boards referred to as media interface cards (MICs). The MICs plug into the I/O carrier card through the front panel with a selectable speed of 10 or 100 Mbps or with a speed of 1 Gbps.

  The number of available ports depends on the installed MICs; see Table 62. Ports 3 to 14 are allocated to the MIC in the left MIC slot; ports 15 to 26 are allocated to the MIC in the right MIC slot. Any MIC can be installed in either slot.

5.3   MIC

MICs allow you to install a variety of ATM OC and Ethernet ports in either of two MIC slots in the chassis front panel. You can install any combination of MICs; if only a single MIC is installed, a MIC slot cover is installed to maintain air flow. Table 62 lists the MICs supported on the SmartEdge 100 router.

(1)  On optical MICs, each port has separate connectors for the transmit (Tx) and receive (Rx) circuits.

(2)  For descriptions of the transceivers supported by this MIC, see Transceivers for SmartEdge and SM Family Line Cards.

Protection for ports is dependent on the release of the SmartEdge OS.

5.4   Alarms
