Removing the 8248-L4T, 8408-E8D, or 9109-RMD processor voltage regulator module

Use this procedure to remove a processor voltage regulator module.

Attention: If you are removing a voltage regulator module to install a new or upgraded voltage regulator module, see Installing the 8248-L4T, 8408-E8D, or 9109-RMD processor voltage regulator module. If you are removing a voltage regulator module as part of a service procedure, continue to use the following procedure.

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

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

  1. Identify the system that you will be working on and turn on the system locate (blue) indicator. For instructions, see Enabling enclosure indicators and Control panel LEDs.
  2. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
  3. Complete the prerequisite tasks. For instructions, see Before you begin.
  4. Stop the system. For instructions, see Stopping a system or logical partition.
  5. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords.
    Note: This system might be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.

  6. Remove the front cover. For instructions, see Removing the front cover from the 8248-L4T, 8408-E8D, or 9109-RMD.
  7. Place the system into the service position. For instructions, see Placing a rack-mounted model into the service position.
  8. Attach the wrist strap.
    Attention:
    • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
    • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
    • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
  9. Press the push button on the planar to turn on the processor voltage regulator rollup LEDs to identify the slot locations.

  10. Complete the following steps to remove a voltage regulator module from the system processor assembly:
    1. Pull the connector tabs (A) up and then out, as shown in the following figure.
    2. Pull the voltage regulator module out of the connector.

  11. Place the voltage regulator module on an electrostatic discharge (ESD) surface.
If you removed the voltage regulator module as part of another service procedure, continue with that procedure. To replace the voltage regulator module or to install a new voltage regulator module, see the following topics:
