1. If the system is not partitioned, shut down the operating system and issue the SRM

power off command. Put the OCP switch in the Off position. Skip step 2.

2. If the system is partitioned, from the console connected to the partition with the

target FRU, shut down the operating system and power it off using the SRM power

off command. Put the PSM(s)’ switch in the Service position. Note, only hard

partitions can be powered off. If soft partitions are used, they must be shut down

and the hard partition must be powered off from the console controlling the

partition.

3. Access the QBB that contains the target FRU. See Section 4.5, Figure 4–5.
