Battery Replacement; Replacing The System Board Battery - HP ML350T06 - E5520 Sff Us Svr Setup And Installation Manual

Battery Replacement

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, short external contacts, dispose of in water or fire, or expose
it to temperatures higher than 60°C (140°F).
CAUTION: To prevent damage to equipment or loss of information, be sure that the
server is powered down, all cables are disconnected from the back of the server, and
the power cord is disconnected from the grounded (earthed) AC outlet before
removing the access panel.
CAUTION: Static electricity can damage electronic components of the server.
Before beginning these procedures, be sure that you are discharged of static
electricity by briefly touching a grounded (earthed) metal object.
This server has nonvolatile memory that requires a battery to retain system
information. The battery is located on the system board.

Replacing the System Board Battery

If the 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 CR2032 3-volt lithium coin cell battery.
To replace the lithium battery:
1. Remove the access panel by following the steps applicable to your tower or rack
server earlier in this chapter.
2. Locate the battery on the system board. See Figure 3-42 for the battery location.
After you have completed the battery installation, restart the system and run RBSU
by pressing the F9 key to reconfigure your system.
NOTE: If you have expansion boards installed, you may need to remove them to access the
battery. Refer to "Installing an Expansion Board" earlier in this chapter.
