Preparing the system for operation after removing and replacing a
power supply

To prepare the system for operation after removing and replacing a power supply, complete the steps in
this procedure.

About this task

Procedure

1.

Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.

2.

Start the system for a nonconcurrent repair. For instuctions, see “Starting the system” on page 108.

3.

Note the state of LEDs on the replaced power supply. The LEDs for that power supply must be in the
following state:

v

The ac power-on LED is On (solid).

v

The dc power-on LED is On (flashing).

v

The amber fault LED is Off.

4.

Verify the installed part. See Verifying a repair in the 8335-GCA or 8335-GTA. (www.ibm.com/
support/knowledgecenter/POWER8//p8ei3/p8ei3_verifyrepair.htm)

5.

If applicable, close the rack door at the rear of the system.

Removing and replacing the power switch and cable in the 8335-GCA
or 8335-GTA

Learn how to remove and replace the power switch and cable in the IBM Power System S822LC
(8335-GCA and 8335-GTA) system.

Removing the power switch and cable from the 8335-GCA or 8335-GTA
system

Follow these steps to remove the power switch and cable from the IBM Power System S822LC (8335-GCA
and 8335-GTA) system.

Procedure

1.

Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.

2.

Remove the disk drive fan card. For instructions, see “Removing the disk drive and fan card from
the 8335-GCA or 8335-GTA” on page 9.

3.

Locate the front USB cable (A) and the power switch cable (B). They connect between the system
backplane and the power switch along the inside of the system. Label each cable.
