I/O backplane (CRU)

Use this procedure to install and remove the backplane.

Parent topic: Non-management console-based procedures

Removing the I/O backplane

If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for removing the I/O backplane from the server. For instructions, see Removing a part using the Hardware Management Console .

If your system is managed by the IBM® Systems Director Management Console (SDMC), use the SDMC to complete the steps for removing the I/O backplane from the server. For instructions, see Removing a part by using the Systems Director Management Console.

If you do not have a management console, complete the following steps to remove the I/O backplane:

  1. Perform the prerequisite tasks described in Before you begin.
  2. Do one of the following steps as appropriate:
    • If you are removing the I/O backplane for a system upgrade or as part of another procedure, continue to step 3.
    • If you are removing the I/O backplane because of a system failure, use the service action log to help identify the failing part. See Identifying a failing part.
  3. Stop the system. For instructions, see Stopping the system or logical partition.
  4. Disconnect the power source from the system by unplugging the system.
    Note: This system might be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.

  5. Disconnect and label the cables from the rear of the I/O backplane.
  6. If you need to replace the I/O backplane because of an upgrade or system failure, remove the adapters from the I/O backplane. For instructions, see Model 5802 and 5877 expansion units, PCI adapters, and cassettes.
  7. Squeeze the release latches (A) and pull the levers (B) out away from the system, as shown in the following figure.

  8. Slide the backplane out of the system.

Replacing the I/O backplane

To remove the I/O backplane, see Removing the 5802 I/O backplane .
If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for replacing the I/O backplane in the server. For instructions, see Replacing a part using the Hardware Management Console .

If your system is managed by the IBM Systems Director Management Console (SDMC), use the SDMC to complete the steps for replacing the I/O backplane in the server. For instructions, see Replacing a part by using the Systems Director Management Console.

If you do not have a management console, complete the following steps to replace the I/O backplane:

  1. Perform the prerequisite tasks as described in Before you begin.
  2. Before installing the I/O backplane, inspect the signal connector pins to ensure that the pins are not bent or damaged.
    Attention: Bent pins damage the midplane receptacle. Be careful not to touch or damage the signal connector pins.
  3. Carefully lift and align the I/O backplane with the slot at the rear of the expansion unit.
  4. Insert the I/O backplane firmly into the server, as shown in the following figure.
  5. Secure the I/O backplane with the locking tabs (A) as shown in the following figure.

If you are replacing the I/O backplane as a part of another procedure, return to that procedure now.

If you are replacing the I/O backplane to repair a failed unit, you can now reinstall the adapters and resume operation. For instructions, see Model 5802 and 5877 expansion units, PCI adapters, and cassettes.
