HPSA590

This procedure refers to a high performance switch (HPS) switch network interface (SNI) in an 590 or 595 server.

You might find this FRU listed in the Part number field in the FRU list in a Serviceable Event Details panel. You need to follow this procedure only after you isolate the cause of the serviceable event to an HPS SNI. Two reasons occur for a Symbolic FRU to be displayed instead of a part number:

Valid SNI location codes do not include any number sign characters. When you have a valid SNI code, look up the part number for a 1-port SNI in the Parts Catalog section of the High Performance Switch Planning, Installation, and Service for eServer p5 servers manual, order number SA38-0646.

When the SNI location code is not valid or is not fully known, you need to determine both the location of the SNI and the part number. To help you determine the location of the SNI, you must use either the other side of the cable or the provided frame and slot location.

The basic flow of the following procedure consists of these actions:

  1. Write down specific information about the frame, slot, reference code, and reference code extension.
  2. Determine the location of the SNI.
  3. Verify that you have identified the correct part.
  4. Write down the part number.
Note: After you complete this procedure but before you continue with your service action, make sure to read the notes in Before you proceed.

To perform this procedure, complete the following steps:

  1. Record the frame and slot information from the text in the Serviceable Event Details panel.
  2. Record the reference code for the Serviceable Event.
  3. Record the reference code extension for the Serviceable Event.
  4. Review the information in the FRU list. Does the Serviceable Event list an SNI FRU and a switch port connection card (SPCC) FRU?
    • No: Go to step 5.
    • Yes: Determine if you have a valid location code for the SPCC.
      1. Do you have a valid location code for the SPCC?
        • No: Go to step 4.b.
        • Yes: Do the following:
          1. Record the location of the SPCC that has a valid location.
          2. Go to the HPSNM Switch Topology View on the CSM Management Server Console, find the SPCC location that you wrote down from the previous step, and click the SPCC location.
          3. Click Selected-Properties.
          4. Click the Connected-To tab.
          5. Is the location code valid in the Connected-To tab?
            • Yes: The location code in the Connect-To tab is the location code for the SNI. This ends the procedure.
            • No: Refer to your cable planning documentation or a cable label to determine which SNI is connected to this SPCC port. This ends the procedure.
      2. You do not have a valid location code for either the SNI or the SPCC. Does the reference code that you wrote down in step 2 begin with BB10, BB20, or BB50?
        • No: Go to step 4.c.
        • Yes: The frame and slot information that you wrote down in step 1 indicate the location of the switch.
          Note: The SPCC card number (Cx) in the location code of the SPCC should be valid.
          1. Go to the HPSNM Switch Topology View on the CSM Management Server Console and find the SPCC location that you recorded previously. Click on that row.
          2. Click Selected-Properties.
          3. Click the Connected-To tab. Is the location code valid in the Connected-To tab?
            • Yes: The location code listed in the Connected-To tab is the location code for the SNI. This ends the procedure.
            • No: Refer to your cable planning documentation or a cable label, or trace the cable to determine which SNI is connected to this SPCC port.
      3. You do not have a valid location code for either the SNI or the SPCC. Does the reference code that you wrote down in step 2 begin with BB30 or BB40?
        • No: Go to step 5.
        • Yes: The reference code extension for the serviceable event that you wrote down in step 3 indicates the logical location of the port on the SNI that reported the problem.
          1. Break down the reference code extension. Use Breaking down a reference code for an SNI as a guide. Write down the frame number, slot number, chip number and port number.
          2. Go to the HPSNM Endpoint View on the CSM Management Server and find the row that matches the reference code extension data from the previous step. (The chip number is labeled Adapter number in the GUI.) Click on that row.
          3. Is the location code valid in the HPSNM Endpoint View?
            • Yes: The location code in the GUI is the location code of the SNI. This ends the procedure.
            • No: Do the following:
              1. Click Selected-Properties.
              2. Click the Connected-To tab. Is the location code valid in the Connected-To tab?
                • Yes: The location code listed in the Connected-To tab is the location code for the SPCC to which the SNI is connected. This ends the procedure.
                • No: Determine the SPCC to which the SNI is connected.
                  1. Write down the frame and slot of this SPCC. This frame and slot indicate the location of the switch planar to which the SPCC is connected.
                  2. The SPCC card number (Cx) in the location code should be valid. Use this to find the specific SPCC card that is plugged into the switch planar that you identified in the previous step.
          4. Use your cable planning documentation or a cable label, or trace the cable to determine which SNI is connected to this SPCC port. This ends the procedure.
  5. Review the information in the FRU list. The Serviceable Event lists one SNI FRU and no SPCC FRU.
    Note: The frame and slot in the Serviceable Event Text that you recorded in step 3 indicates where to locate the server that contains the SNI.
    1. Break down the reference code extension. Use Breaking down a reference code for an SNI as a guide. Write down the frame number, slot number, chip number and port number.
    2. Go to the HPSNM Endpoint View on the CSM Management Server and find the row that matches the reference code extension data from the previous step. (The chip number is labeled Adapter number in the GUI.) Click on that row.
    3. Click Selected-Properties.
    4. Is the location code valid in the Selected-Properties panel?
      • Yes: The location code listed in the Selected-Properties panel is the location code for the SNI. This ends the procedure.
      • No: Does the server in the specified frame and slot contain more than one SNI card?
        • No: Only one SNI card is in the server. The location code listed in the Selected-Properties panel is the location code for SNI. This ends the procedure.
        • Yes: More than one SNI card is in the server. Call your next level of support to help find the correct SNI. This ends the procedure.

Breaking down a reference code for an SNI

The following table shows how to break down a sample reference code for a switch network interface (SNI): 0000000040512330. The data for this reference code are frame 4, slot 5, chip 3, port 0.

Table 1. Breaking down SNI reference code 0000000040512330
5 chars 1 char 3 chars 2 chars 2 chars 1 char 1 char 1 char
Reserved=0 Network Frame number Slot number Reserved Card Chip Port
00000 0 004 05 12 3 3 0

Before you proceed

Notes:
  1. Before you replace the SNI, make sure that you run diagnostics.
  2. Try to verify the presence of a flashing LED on the SNI card that you are planning to service. The lack of a flashing LED is not a positive indicator that this is not the correct switch.
  3. You can get the part number by looking on the part itself, then cross-referencing that number to the Parts Catalog section of the High Performance Switch Planning, Installation, and Service for eServer p5 servers manual, order number SA38-0646. The part number should be for a 1-link SNI.
