REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW:  Power supply failure

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

The server is equipped with redundant hot-swappable power supplies. Redundant power supplies enable you to remove and replace a power supply without shutting the server down, provided that at least two other power supplies are online and working.

WHAT ACTIONS ARE REQUIRED:

A) Remove a Power Supply

1. Identify which power supply requires replacement. An amber LED on a power supply indicates that a failure was detected. In addition, the show faulty command indicates which power supply is faulty.

2. Follow standard ESD precautions. Access to the rear of the server where the faulty power supply is located. If necessary, slide the system partially out of the rack to obtain better access to the rear panel.

3. Disconnect the power cord from the faulty power supply.
4. Grasp the power supply handle and press the release latch.
5. Pull the power supply out of the chassis.

Note: Power supply zero (PS 0) is lower slot, Power supply 3 (PS 3) is in the upper slot. If you are servicing Power Supply 0, you have to disconnect the cable management arm support strut.

B) Install a Power Supply

1. Align the replacement power supply with the empty power supply bay.

2. Slide the power supply into the bay until it is fully seated.

3. Reconnect the power cord to the power supply. Verify that the power supply LED is green or blinking green.

4. Verify that the system Power Supply Fault LED, and the front and rear Service Required LEDs are not lit.

5. At the Oracle ILOM -> prompt, use the show faulty command to verify the status of the power supplies.
