Removing the 9117-MMB or 9179-MHB power supply with the power turned off

If your system power is already turned off, or if you want to perform another service task with power turned off, learn how to remove a power supply with the system 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 SDMC, complete the following steps to remove the power supply from a system while the system power is turned off:

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

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

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

4.Open the back rack door.

5.Disconnect the power source from the system by unplugging the system, as described in Disconnecting the power cords.

Note: This system is equipped with a second power supply. Before continuing with this procedure, disconnect all power sources to the system.
