Removing a VRM
Use the following information and steps when removing a VRM.
Caution: VRM must be appropriate: You might damage the system if you install a
VRM that is inappropriate for your system. For exact information about VRM and
processor interchangeability, contact your customer service representative.
Note: Reduce the risk of electrostatic discharge (ESD) damage to the VRM by doing the
following:
• Touch the metal chassis before touching the VRM or baseboard.
• Keep part of your body in contact with the metal chassis to dissipate the static
charge while handling the VRM.
• Avoid moving around unnecessarily.
1. Read and observe the safety and ESD precautions atthe beginningof Chapter 1and
the additional cautions given here.
2. Remove the access cover and the rear foam cover over the electronics bay.
3. As you work, place VRMs on a grounded, static-free surface or conductive foam
pad.
4. Using a small flat-bladed screwdriver, push the plastic ejector levers on each end of
the connector away from the VRM to eject it out of the connector.
5. Place the VRM on a nonconductive, static-free surface, or store it in an antistatic
protective wrapper.
