Removing a VRM

CAUTIONS

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.

ESD and handling processors: 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.

To decide what VRM you need to remove, see Figure 1 on page 14.

1.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.

2.Pull 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.

Installing a VRM

To decide what VRM you need to install, see Figure 1 on page 14.

1.Remove the VRM from its protective package.

2.Orient the VRM within the VRM connector correctly. See Figure 6 on page 67.

3.Carefully insert the VRM in the connector on the baseboard. Make sure you do not bend the connector pins.

4.Push down firmly on both ends of the VRM until the ejector levers of the connector snap into place, locking the VRM in the connector.

5.Make sure that the ejector levers are firmly in place. If not, use a screwdriver to push them into place.
