REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW: faulty Power Supply

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The server must have at least two functioning power supplies to operate correctly. There are no restrictions into which slots the power supplies have to be installed, so if you have only two power supplies, they can be installed in any of the four power supply slots. If you need to replace a power supply and your server has only two power supplies installed, you must power down the server before you can replace the power supply.

If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.

 
WHAT ACTIONS ARE REQUIRED:

A) Locate a Faulty Power Supply

The following LEDs are lit when a power supply fault is detected:

- System Service Required LEDs on the front panel and rear I/O module
- Fault LED on the faulty power supply

From the front of the server, check the power supply fault LEDs to identify which power supply needs to be replaced.
Each power supply is provided with a set of three LEDs, which are located at the front of the server.

NOTE - If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.

B) Remove a Power Supply

The power supply is a hot-service component that can be replaced by a customer.

1. Locate the power supply in the server that you want to remove (see above)

2. Determine if you can hot-swap the power supply:

If there are at least three power supplies installed, you can hot-swap the faulty power supply without shutting down the server. Go to Step 6.
If there are two or fewer power supplies installed, you must shut down the server before you can remove the power supply. Go to Step 3

3. Power off the server.

4. Go to the rear of the server and locate the AC power connector at the rear of the server that supplies power to the faulty power supply.

5. Disconnect the power cord from the AC power connector that is associated with the power supply that will be replaced.

6. Go to the front of the server and, on the power supply to be removed, squeeze the release latches together, then pull the extraction lever toward you to disengage the power supply from the server.

7. Pull the power supply out of the server.

8. Install the replacement power supply.

C) Install a Power Supply

1. Align the replacement power supply with the empty power supply chassis bay.
Verify that the extraction lever on the power supply is on the right side of the power supply and that the power supply is oriented correctly.

2. Slide the power supply into the chassis.

3. Press the lever against the power supply to fully seat the power supply in the server.

4. If you disconnected the power cord for the power supply (if you had to cold-service the power supply), go to the rear of the server and plug the power cord into the AC connector that is associated with the power supply that you just inserted.

5. As soon as power is applied to the server, standby power initializes the service processor. Depending on the server's OpenBoot PROM settings, the host server might automatically boot, or you might need to boot it manually.

C) Verify Power Supply Functionality

1. Verify that the power supply Power OK and AC Present LEDs are lit, and that the Fault LED is not lit.

2. Verify that the front and rear Service Required LEDs are not lit.

If Step 1 and Step 2 indicate that no faults have been detected, then the power supply has been replaced successfully. No further action is required.
