Installing A New Voltage Regulator Module - HP D7171A - NetServer - LPr Installation Manual

Chapter 1

Installing a New Voltage Regulator Module

One voltage regulator module (VRM) must be installed for each processor
module installed. If only one processor module is installed, a VRM must be
installed in the primary (lower) VRM socket.
To install a new VRM:
1. Orient the new VRM as shown in Figure 1-13.
2. Holding the new VRM as shown, press it firmly into the VRM socket on
the processor board. Be sure to press only on the thin edge of the main
VRM board when inserting the VRM into the socket.
CAUTION When installing the new VRM, push only on the edge of the
main VRM board (see Figure 1-13). Do not push on the large
flat surface (if your VRM model has one) or any components
on the board. Pushing on any part of the VRM except the
edge of the main board may result in damage to the VRM.
Damage caused by improper installation is not covered by any
HP warranty.
3. Verify that the VRM is installed completely in the socket. When the VRM
is installed completely, the release latches (see Figure 1-13) at the ends of
the socket will be closed.
CAUTION
Do not push in on the VRM release latches; the release
latches will close automatically when the VRM is installed
completely. If the VRM is not installed completely, pushing
in on release latches may damage the latches, the socket, or
the VRM.
