Replacing an 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 power supply with power off

Learn how to replace a power supply with the system power off.

If your system is managed by the Hardware Management Console (HMC), you can use the HMC to complete the steps for replacing a power supply. For instructions, see Exchanging a part using the Hardware Management Console.

To replace a power supply in a system that is not managed by an HMC while the system power is off, complete the following steps:

  1. To remove the power supply, see Removing an 8203-E4A, 8204-E8A, 9407-M15, 9408-M25, or 9409-M50 power supply with power off.
  2. Push the power supply (A) into the system until the latch locks in place as shown in Figure 1.

  5. Start the system, as described in Starting the system or logical partition.
  6. Note the state of the light-emitting diodes (LEDs) on the power supply. For more information, see Power supply LEDs. If the LEDs indicate the power supply is operating normally, that is both of the green LEDs are on solid (not blinking), continue to the next step. If not, remove the power supply from the system and repeat the procedure. If, after repeating the procedure, the power supply is not operating normally, contact your service provider.
  7. Replace the front cover, as described in Installing the front cover on a rack-mounted model or Installing the front cover on a stand-alone model.
  8. Close the back rack door.
