Servicing Your Mainframe

Chapter 5

Replacing the

HP E8404A Power

Supply

1. Turn off the mainframe and remove the power cord.

2. Remove the rear panel. Refer to “Removing the Rear Panel from the 

Mainframe” on page 207 for instructions.

3. Using the rings on the power supply, gently pull the supply out from 

the plastic connectors on the backplane adapter board. Do not carry 
the supply using the rings.

4. Install the exchange power supply. Keep the replacement power 

supply to the far right in the mainframe. Make sure the supply is 
firmly inserted into the backplane connectors. 

5. Replace the rear panel. Make certain that all 14 screws are secured.

Note

You must recalibrate the Enhanced Monitor after replacing the power 
supply. Refer to Chapter 4 for calibration details.
