FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

   PROBLEM OVERVIEW:

Faulty Power Supply

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

A data backup is not a pre-requisite but is a wise precaution.
It is not required to perform a system shutdown to replace the power supply.

   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

Removing power supply:

1. Locate the power supply that you need to remove. If the power supply is in a fault state, the amber Service Action Required LED is on.
    The server contains four power supplies (PS0–PS3). The power supplies are designated PS0–PS3, with PS0 residing in the bottom slot and PS3 residing in the top slot.

2. To unlock the power supply, firmly squeeze the end of the release handle.
    The power supply release handle is located at the bottom of the power supply. The handle clicks when the locking mechanism is released.

3. Pull the release handle out and to the right until the handle is fully extended.
    This action removes the pawl (slotted wheel at end of  handle) from the locking slot.

4. Use the handle to pull the unit partially out of the slot.
    Pull the unit out far enough to grab it with your hands.

5. Close the release handle by moving it to the left until it locks.

6. To remove the power supply, slowly slide it out of the slot with one hand while supporting it with the other hand.

Installing power supply:

1. Ensure that the release handle on the power supply is in its fully open position.
    The handle should extended away from the power supply.

2. Position the power supply at the opening with the LEDs to the left and the release handle at the bottom.
    Correct positioning ensures that the connector on the power supply is aligned with the connector on the internal backplane of the server.

3. Slide the power supply into the opening until it stops.

4. Ensure that the pawl (slotted wheel) on the end of the handle is aligned with the opening on the side of the power supply slot.

5. To engage and set the power supply connector with the connector on the internal backplane, push the end of the release handle to the left.

6. Continue to push the release handle until the handle locks into place under the bottom edge of the power supply.
    This action produces a click when the lock engages. In this position, the power supply cannot be slid out of the server unless the release handle is unlocked and lifted first.
