HPSSSW

This procedures refers to a high performance switch (HPS) planar.

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 a switch planar. Two reasons occur for a Symbolic FRU to be displayed instead of a part number:

Valid switch planar location codes do not include any number sign characters. When you have a valid switch planar code, look up the switch planar part number 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 switch planar location code is not valid or is not fully known, you need to determine the location of the switch planar. To help you determine the location of the switch planar, 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 code for the switch planar.
  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 two switch planar FRUs?
    • No: Go to step 5.
    • Yes: Determine if you have a valid location code for the other switch planar.
      1. Do you have a valid location code for the other switch planar?
        • No: Go to step 4.b.
        • Yes: Do the following:
          1. Find the SPCC that corresponds to the switch planar that has the valid location code. The SPCC has the same unit location as the switch planar: U7045.SW4.[serial number]. Record the location of the switch port connection card.
          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. Write down the frame and slot of the port on the other side of the cable, which indicate the location of the switch planar. This ends the procedure.
      2. You do not have a valid location code for either switch planar. Is this the first switch in the FRU list?
        • No: Go to step 4.c.
        • Yes: The frame and slot information in the Serviceable Event text that you wrote down in step 1 indicates the location of the switch you are trying to find. This ends the procedure.
      3. You do not have a valid location code for either switch planar. This is the second switch in the FRU list. Do the following:
        Note: The reference code extension for the serviceable event that you wrote down in step 3 indicates the location of the port on the other switch that reported the problem.
        1. Break down the reference code extension. Use Breaking down a reference code for a switch as a guide. Write down the frame number, slot number, chip number and port number.
        2. Go to the HPSNM Switch Topology View on the CSM Management Server and find the row that matches the reference code extension data from the previous step. Click on that row.
        3. Click Selected-Properties.
        4. Click the Connected-To tab. Is the location code valid in the Connected-To tab?
          • Yes: Drop the characters "-Cx-Ty" from the location code in the Connected-To tab, then use that location code for the switch planar. This ends the procedure.
          • No: Write down the frame and slot of the port on the other side of the cable. This frame and slot indicate the location of the switch planar. This ends the procedure.
  5. Review the information in the FRU list. Does the Serviceable Event list one switch planar FRU and a switch network interface (SNI) card FRU?
    • No: Go to step 6.
    • Yes: Check the SNI location code.
      1. Does the SNI have a valid location code?
        • Yes: Do the following:
          1. Write down the location code for the SNI.
          2. Go to the HPSNM End-point View on the CSM Management Server and find the row that matches the SNI location code that you just wrote down. Click on that row.
          3. Click Selected-Properties.
          4. Click the Connected-To tab. Is the location code valid in the Connected-To tab?
            • Yes: Drop the characters "-Cx-Ty" from the location code in the Connected-To tab, then use that location code for the switch planar. This ends the procedure.
            • No: Write down the frame and slot of the port on the other side of the cable, which indicate the location of the switch planar. This ends the procedure.
        • No: Look at the beginning characters of the reference code that you wrote down step 2.

          For reference codes that begin with BB10, BB20, or BB50: The frame and slot in the Serviceable Event Text indicate the location of the switch planar. This ends the procedure.

          For reference code that begin with BB30 or BB40: Do the following:

          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. Click the Connected-To tab. Is the location code valid in the Connected-To tab?
            • Yes: Drop the characters "-Cx-Ty" from the location code in the Connected-To tab, then use that location code for the switch planar. This ends the procedure.
            • No: Write down the frame and slot of the port on the other side of the cable. This frame and slot indicate the location of the switch planar. This ends the procedure.
  6. Review the information in the FRU list. The Serviceable Event lists only one switch planar FRU and does not include an SNI FRU.

    The frame and slot in the Serviceable Event Text indicate where to locate the switch planar. This ends the procedure.

    Note: You can double check this by going to the HPSNM Switch Topology View and finding the switch for the indicated frame and slot. Expand the ports and look to see if a valid location code exists for any of the ports. If you see a valid location code, drop the characters "-Cx-Ty" from the location code, then use that as the location code for the switch planar.

Before you proceed

Notes:
  1. Before you replace the switch planar, make sure that you run diagnostics.
  2. If an SPCC appears in the FRU list, try to verify that presences of a flashing LED on the SPCC card in the same enclosure as the switch planar that you are going 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.
