Installing the System Board Battery

WARNING: The System Board contains a clock/CMOS lithium battery. The lithium battery may explode if mistreated. The battery is soldered in place and may not be removed. Do not abuse or disassemble. Use only replacement batteries supplied by Compaq Computer Corporation (spare part number

160274-001).

To install the new battery, complete the following steps:

1.If the server is on, place it in Standby and disconnect the power cord-(s). See to Chapter 2, “Server Installation Overview”.

2.Pull the server forward in the rack for access to the inside of the server.

3.Remove the server cover.

4.Locate the battery header. The following illustration identifies the header location for the new battery.
