c. Use the recessed fan handle (B) to lift the fan from the power-supply assembly, as shown in
Figure 11 on page 12.
If you removed the power supply or fan as part of another service action, or if you want to replace the
power supply or fan that you removed from an expansion unit, see Replacing a power supply or fan in a
5802 or 5877 expansion unit with the power turned on.

with the 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 an HMC or an 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.
6. At the front of the expansion unit, slide the cable retention bracket for the power supply that you
want to remove, to the open position (A) . Disconnect the cable (B) as shown in Figure 13 on page
14.
