Processor cards

Processor cards perform the operations required to manage the resources and data for the expansion or server enclosure.

The processor cards are located in the rear of the enclosure. One of the cards is below the rear operator panel and above the battery backup units. The other card is located below the battery backup units and above the system service card.

The server enclosure and expansion enclosure processor cards provide control and management functions for the storage unit. Each processor card is capable of providing control and management for the entire server or expansion enclosure. For a dual processor card design, a single processor card can control the entire enclosure in the event of a processor card failure.

There are two types of processor cards. The server enclosure processor card, shown in Figure 1, can be installed in the server enclosure. It contains two disk expansion ports, two disk controller ports, power on and system alert LED indicators, an Ethernet connection port, one RJ-12 serial connection port and four host SFP ports.

Figure 1. Server enclosure processor card

The expansion enclosure processor card, shown in Figure 2, can be installed in the expansion enclosure. It contains two disk expansion ports, two disk controller ports, power on and system alert LED indicators, and an RJ-12 serial connection port.

Figure 2. Expansion enclosure processor card

Fiber optic cables and SFP connectors connect your storage unit with host systems and attach expansion enclosures to your server enclosure. The fiber optic SFP ports are the disk expansion, disk controller and host ports that are located on the processor controller card in the enclosure.

Note: The expansion enclosure processor card does not contain host SFP ports. These are only located on the server enclosure processor card.

Ethernet cables are used to connect the storage unit to your network.

Figure 3 and Figure 4 show the LED indicators that are included in the processor cards and their location on the cards.Table 1 describe the different states for the indicators on the processor cards.

Table 1. Server enclosure and expansion enclosure processor card indicators
Indicator name (color)	Purpose	State descriptions
Power on (green)	Indicates the state of the DC power available to the processor card.	Solid: DC power is being delivered to the processor card Flashing: Main DC power is not present. +3.3 volt standby power is available to the processor card. Off: DC input power is not present in any form.
Service/fault (amber)	Indicates that a fault condition has been detected within the processor card	Solid: A fault condition has been detected and this processor card requires service. Flashing: This processor card has been identified by system management. Off: No known faults exist. This is the default state for this indicator.
Host port SFPs	Indicate the state of the host port. This indicator is available only on the server enclosure processor card.	The host SFP ports have the following three LED indicators: Host port activity indicator (green, top left) Host port activity indicator (green, bottom left) Service/fault indicator (amber, top right). The service/fault indicator can have the following three states: Solid: A fault condition has been detected on the host SFP port. Flashing: A fault condition has been detected and this host SFP port requires service. Off: No known faults exist. The host SFP port is operating normally. See Table 2 for descriptions of the states of these indicators.
Disk controller port SFPs	Indicate the state of the disk controller port.	The disk controller SFP ports have the following LED indicators: Device port activity indicator (green, top left) Device port activity indicator (amber, top right) See Table 3 for descriptions of the states of these indicators.
Storage disk expansion port SFPs	Indicate the state of the storage disk expansion ports.	The storage disk expansion SFP port have the following LED indicators: Device port activity indicator (green, top left) Device port activity indicator (amber, top right) See Table 4 for descriptions of the states of these indicators.
Ethernet ports	Indicate the state of the Ethernet connection to the network. This indicator is only available on the server enclosure processor card.	The Ethernet ports have the following LED indicators: Link status (left) Link activity (right) See Table 5 for descriptions of the states of these indicators.

Table 2. Host SFP port indicators
Host port activity (green, top left)	Host port activity (green, bottom left)	Host SFP port state
Off	Off	Wake up failure
Off	On	POST failure
Off	Flashing (slow)	Wake up failure monitor
Off	Flashing (fast)	Failures in POST
Off	Flashing (irregular)	POST processing is in progress
On	Off	Failure while functioning
On	On	Failure while functioning
On	Flashing (slow)	Normal (Link online at X GHz)
On	Flashing (fast)	Normal (Link online at 2X GHz)
On	Flashing (irregular)	Not defined
Flashing (slow)	Off	Normal - link down
Flashing (slow)	On	Not defined
Flashing (slow)	Flashing (slow)	Offline for download
Flashing (slow)	Flashing (fast)	Restricted offline mode (waiting for restart)
Flashing (slow)	Flashing (irregular)	Restricted offline mode, test active
Flashing (fast)	Off	Debug monitor in restricted mode
Flashing (fast)	On	Not defined
Flashing (fast)	Flashing (slow)	Debug monitor in test fixture mode
Flashing (fast)	Flashing (fast)	Debug monitor in remote mode
Flashing (fast)	Flashing (irregular)	Not defined

Table 3. Disk controller SFP port indicators
Device port activity indicator (green, top left)	Device port activity indicator (amber, top right)	Disk controller SFP port state
On	Off	All of the following conditions exist: The processor card is attached to the fibre-channel loop The fibre-channel arbitrated loop is working (but not necessarily in use) Initial machine load (IML) was successful
Off	Off	One of the following conditions exists: IML was not successful No cables are attached to the processor card The device subsystem fibre-channel interface controller is resetting during a configuration The fibre-channel connection is bad, either due to a faulty cable or a continuously resetting loop

Table 4. Storage disk expansion SFP port indicators
Device port activity indicator (green, top left)	Device port activity indicator (amber, top right)	Disk expansion SFP port state
Off	Off	This is normal port status when SFP is not installed.
Off	On	A fault condition with the SFP has been detected.
Off	Flashing	A situation has occurred that requires identification of this processor card by the service package.
Off	Flashing (fast)	Failure in POST
Off	Flashing (irregular)	POST processing is in progress
On	Off	Normal operation. There is no activity.
On	On	Port is bypassed. One of the two conditions exist: The SFP is installed, but the port is not receiving a valid signal The port is receiving an F8 failure notification from the attached device
On	Flashing	The port is manually bypassed.
Flashing	Off	Normal operation. The data is being transferred between the port and the attached device.

Table 5. Ethernet port indicators
Connection speed (left)	Duplex status (right)	Ethernet connection state

On	Off	The Ethernet link is established at 100 Mbps and half duplex.
Off	On	The Ethernet link is established at 10 Mbps and full duplex.
Off	Off	Either no Ethernet link is present or the link is established at 10 Mbps and half duplex.
