Install an InfiniBand Cable

1. Identify the prerequisite and subsequent tasks you must perform in conjunction with this procedure, to achieve a goal.

   See the table in Servicing the InfiniBand Cables.

2. Consider your next steps:

   • If you are cabling an entire line card after a replacement procedure, go to Step 3.

   • If you are installing a replacement cable to the switch, go to Step 5.

3. Locate the cable for the connector 0B.

4. Go to Step 9.

5. Inspect the replacement InfiniBand cable.

   See Inspecting the InfiniBand Cables.

6. Bring the replacement cable to the switch.

7. Lay the cable over the cable curve.

8. Feed the cable through the side branch of the cable tree.

   
   

9. Curve the cable through the main trunk of the cable tree.

   Caution - Do not allow any copper core InfiniBand cable to bend tighter than a 5 inch (127 mm) radius. Do not allow any optical InfiniBand cable to bend tighter than a 3.4 inch (85 mm) radius. Tight bends can damage the cable internally.

10. Plug the cable into the appropriate connector.

    
    

    1. Visually inspect the cable connector to see whether the shell is not bent and is parallel to the inner boards.

       If the shell is bent or damaged, get a different cable.

    2. Ensure that the retraction strap is forward.

    3. Orient the cable connector to horizontal.

       Ensure that the upper shell just touches the underside of the top of the receptacle on the line card.

       
       

    4. Slowly move the connector in.

       As you slide the connector in, the top of the shell should scrape against the underside of the top of the receptacle on the line card.

       • If the cable stops or binds after about 5 mm (1/4 in.) travel, back out and repeat Step c and Step d.

       • If the connector stops or binds with about 2 mm (1/8 in.) still to go, back out and repeat Step c and Step d.

    5. Continue to push the connector in until the hooks catch onto the top of the connector on the line card.

11. Consider your next step:

    • If you are replacing a cable at connectors 6A through 11B, repeat Step 8 through Step 10, moving to the left, working your way to connector 6A.

      For example, if you are replacing cable 9A, install 9A, 8B, 8A, 7B, and so on to 6B and 6A.

    • If you are replacing a cable at connectors 0A through 5B, repeat Step 8 through Step 10, moving to the right, working your way to connector 5B.

      For example, if you are replacing cable 2B, install 2B, 2A, 3B, 3A, and so on to 5B and 5A

    • If you are installing all cables as part of a line card replacement procedure, repeat Step 8 through Step 10, moving to the right, working your way to connector 5B. Then repeat Step 8 through Step 10 with the cable to connector 11A, moving to the left, working your way to connector 6B.

      For example, 0B, 0A, 1B and so on to 5B and 5A. Then 11B, 11A, 10B, and so on to 6B and 6A.

12. (Optional) Display and record the replacement cable’s FRU ID information:

    # clia fruinfo IPMB_address FRU_number

    where:

    • IPMB_address is from Component Addressing.

    • FRU_number is from Connector Addressing

    The following example is the output for connector 2A on line card 1:

    # clia fruinfo 84 6

    Note - Retrieving FRU ID information from an InfiniBand cable is only possible if the cable supports the IPMI specification for providing FRU ID information.
