FIELD ENGINEER INSTRUCTIONS

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

The server's redundant power supplies support concurrent maintenance, which enables you to remove and replace a power supply without shutting down the server, provided that the other power supply is online and working.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1.Confirm the Power Supply failure and it's location.

1. Confirm which Power Supply is to be replaced. When looking at the server from the rear PS0 is to the left and PS1 is to the right.
2. If the specific power supply to be replaced is not yet known check the status LEDs to identify the failed Power Supply. A failed PSU should have it's amber "service action required" LED lit. A working PSU will have both it's green "AC OK" and "DC OK" LEDs lit.
3. If the service is to be performed while the system is up and running confirm that the second PSU is online and working properly.
4. If a replacement Power Supply is not yet available leave the failed supply in place to provide proper airflow within the system until the replacement is available. You may notice that the failed Power Supply's fans are still turning. This is ok and the power supply may be removed while the fans are still spinning.

2. Remove the Power Supply

1. Gain access to the rear of the server where the faulty power supply is located.
2. Release the cable management arm (CMA), If one is installed. Press and hold the CMA release tab.
3. Rotate the cable management arm out of the way so that you can access the power supply.
4. Disconnect the power cord from the failed power supply.
5. Press down on the release latch and rotate it forward/down to disengage the supply from the server.
6. Pull the power supply out of the chassis and set it aside on an antistatic mat.

3. Install the replacement Power Supply

1. Remove the replacement power supply from its packaging and place it on an antistatic mat.
2. Align the power supply with the empty power supply bay.
3. Slide the power supply into the bay until it is fully seated.
4. Rotate the release latch up to secure the power supply into place.
5. Reconnect the power cord to the power supply.
6. Verify that the amber LED on the replaced power supply and the Service Required LEDs on the chassis are not lit.

4.Return the Server to operation

1. If you pulled the server out of the rack to make it easier to remove the power supply, push the server into the rack until the slide-rail locks (on the front of the server) engage the slide-rail assemblies.
2. If a cable management arm is installed and was removed to access the power supply reattach the CMA clip to the slide rail.
3. Check all power and data cables to ensure that no connections were disturbed during the service.
4. Verify that the Power/OK indicator led lights steady on and that system is operating properly.
