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 ("Powering down the server" on page 15).
2. Extend or remove the server from the rack ("Preparation procedures" on page 16).
3. Remove the access panel ("Removing the access panel" on page 17).
4. Remove the PCI riser cage ("Removing the PCI riser board assembly" on page 17).
CAUTION: To prevent damage to the server or expansion boards, power down the server and remove all
AC power cords before removing or installing the PCI riser cage.
5. 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.
