3: Removing and Installing Baseboard Components
Removing a VRM
To decide which VRM you need to remove, see Figure 3-1 on page 52.
Caution: 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.
Caution: Reduce the risk of electrostatic discharge (ESD) damage to the VRM by doing
the following: (1) 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. (2) Avoid moving around unnecessarily.
1. Using a small flat-head screwdriver, push the plastic ejector levers on each end of
the connector away from the VRM to eject it out of the connector. See Figure 3-5 for
the location of the ejector levers.
2. Pull the VRM straight up and out of the baseboard.
3. Place the VRM on a nonconductive, static-free surface, or store it in an antistatic
protective wrapper.

To decide on which connector you need to install a VRM, see Figure 3-1 on page 52.

2. Orient the VRM in the VRM connector correctly. See Figure 3-5.
