Battery replacement
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. Under normal use, battery life is 5 to 10 years.
WARNING: The computer contains an internal lithium manganese dioxide, a vanadium
pentoxide, or an alkaline battery pack. A risk of fire and burns exists if the battery pack is not
properly handled. To reduce the risk of personal injury:
• Do not attempt to recharge the battery.
• Do not expose the battery to temperatures higher than 60°C (140°F).
• Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
• Replace only with the spare designated for this product.
To remove the component:
1. Power down the server (on page 20).
2. Do one of the following:
o Open or remove the tower bezel, as needed ("Open or remove the tower bezel" on page 20).
o Extend the server from the rack (on page 21).
3. Remove the access panel (on page 21).
4. Remove the battery.
IMPORTANT: Replacing the system board battery resets the system ROM to its default
configuration. After replacing the battery, reconfigure the system through RBSU.
To replace the component, reverse the removal procedure.
