Replacing A Battery; Replacing The System Board Battery - Compaq ML330e - ProLiant - 64 MB RAM Maintenance And Service Manual

Replacing a Battery

The ProLiant ML330e/ML330 server has nonvolatile memory, which requires a battery to retain
system information. There is a battery on the system board and a battery on the Server Feature
Board. These batteries are required to maintain certain system data.

Replacing the System Board Battery

If your server no longer automatically displays the correct date and time, you may need to
replace the battery that provides power to the real-time clock. When replacing a battery, use a
3-volt CR2032 lithium coin cell battery.
To replace the lithium coin cell battery from the system board:
1. Complete the preparation procedures. See "Preparation Procedures" earlier in this chapter.
2. Remove the front bezel. See "Front Bezel" earlier in this chapter.
3. Remove the access panel. See "Access Panel" earlier in this chapter.
WARNING: The system board contains a lithium battery. There is a risk of fire and chemical
burn if the battery is improperly handled. Do not disassemble, crush, puncture, or short
external contacts, dispose of in water or fire, or expose the battery to temperatures higher than
60°C (140°F).
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you
are properly grounded (earthed) before beginning any installation procedure. See "Electrostatic
Discharge Information" earlier in this chapter for more information.
