Removing the 8203-E4A, 8261-E4S, 9407-M15, or 9408-M25 voltage regulator module

Learn how to remove a voltage regulator module.

If your system is managed by the Hardware Management Console (HMC), use the HMC to remove a voltage regulator module from the server. For information about using the HMC to remove the voltage regulator module, see Removing a part using the Hardware Management Console.

If you do not have an HMC, complete the following steps to remove a voltage regulator module:

Perform the prerequisite tasks as described in Before you begin.
Stop the system. For instructions, see Stopping a system or logical partition.
Remove the front cover:
- For a rack-mounted system unit, see Removing the front cover from a rack-mounted 8203-E4A, 8204-E8A, 8261-E4S, 9407-M15, 9408-M25, or 9409-M50.
- For a desk-side system, see Removing the front cover from the stand-alone 8203-E4A, 8204-E8A, 8261-E4S, 9407-M15, 9408-M25, or 9409-M50.
On a rack-mounted system unit, open the back rack door.
Disconnect the power source from the system by unplugging the system.
Note: This system can be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.
If you have a rack-mounted system, place it in the service position. For instructions, see Placing a rack-mounted 8203-E4A, 8204-E8A, 8261-E4S, 9407-M15, 9408-M25, or 9409-M50 in the service position.
Remove the service access cover:
- For a rack-mounted system unit, see Removing the service access cover from a rack-mounted 8203-E4A, 8204-E8A, 8261-E4S, 9407-M15, 9408-M25, or 9409-M50.
- For a desk-side system unit, see Removing the service access cover from a stand-alone 8203-E4A, 8204-E8A, 8261-E4S, 9407-M15, 9408-M25, or 9409-M50.
Remove the fans by lifting the tab (A) for each fan, and lifting the fan out of the system as shown in the following figure:

To remove a voltage regulator module from the system processor assembly, follow these steps:
1. Push the connector tabs (A) out and then down, as shown in the following figure.
2. Pull the voltage regulator module (B) out of the connector.
Place the voltage regulator module on an electrostatic discharge (ESD) surface.
