Removing a power supply or fan from a 5802 or 5877 expansion unit with power turned off

Learn how to remove a power supply or power-supply fan from a 5802 or 5877 expansion unit if you want to replace a failing part with the power turned off.

If your system is managed by the Hardware Management Console (HMC), use the HMC to remove a power supply. For instructions, see Removing a part by using the Hardware Management Console.

If your system is managed by the IBM Systems Director Management Console (SDMC), use the SDMC to remove a power supply in the server. For instructions, see Removing a part by using the Systems Director Management Console.

If your system is not managed by the HMC or SDMC, complete the following steps to remove a power supply or fan from an expansion unit or system while the system power is turned off:

1.Perform the prerequisite tasks, as described in Before you begin.

2.Open the front rack door.

3.Identify the failing part, as described in Identifying a failing part.

4.At the front of the expansion unit, identify the power supply that needs to be replaced. To identify the power supply, observe the state of the amber field-replaceable unit (FRU) fault and identify light-emitting diode (LED) (A) as shown in Figure 12. A lit (on solid or flashing) LED indicates the failing power supply.

5.If the system is running, stop the system as described in Stopping the system or logical partition.
