PROBLEM OVERVIEW: Faulty Power Distribution Board (PDB)

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.
The customer should conduct an orderly software system shutdown.

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

The following procedures describe how to remove and install the Power Distribution Board (PDB) in the Netra 240 server.

Removing the Power Distribution Board:

1. Power off the server.

2. Disconnect the power input cables from both power supply units.

3. Remove the server cover.

4. Open the rotating service module.

5. Ensure that the server is properly grounded.

6. Disconnect the power distribution board wiring harness from the three connectors on the system board

7. Disconnect the power distribution board cable from the SCSI interface board

Caution - The power supplies contain pinch points. Be very careful when opening and closing the levers on the power supplies. Keep your hands and fingers away from the base and sides of the levers. For more information about these pinch points, refer to the power supply labels.

8. Pull the lever on the back of each power supply unit down

- This disconnects the power supply unit from the power distribution board.

9. Slide each power supply unit part of the way out of the server chassis by pulling on the lever

- You do not have to completely remove the power supply units from the server.

10. Using a No. 2 Phillips screwdriver, unscrew the two retaining screws that hold the power distribution board in place

11. Lift the power distribution board up and out of the server.

Installing the Power Distribution Board:

1. Insert the power distribution board in the server chassis.

2. Using a No. 2 Phillips screwdriver, secure the power distribution board to the server using the two retaining screws.

3. Connect the power distribution board cable to the SCSI interface board.

4. Connect the power distribution board wiring harness to the three connectors on the system board.

5. Insert the two power supply units in the power supply unit bays.

6. Slide each power supply unit into the server until you feel it engage with the power distribution board.

- Ensure that the lever does not return to a vertical position until the power supply unit engages with the power distribution board. If the lever returns to vertical, the power supply unit does not engage correctly.

7. Press the lever up on each power supply unit until it clicks.

- Returning the lever to a vertical position engages the power supply unit with the power distribution board inside the server.

8. Close the rotating service module.

9. Install the server cover.

10. Power on the server.
