System battery replacement
If the server blade no longer automatically displays the correct date and time, then 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 blade (on page 14).
2. Remove the server blade (on page 15).
3. Place the server blade on a flat, level work surface.
4. Remove the access panel (on page 15).
5. Identify the battery location ("System board components" on page 11).
6. If installed, remove the direct connect SATA cable ("Remove the direct connect SATA cable" on
page 19).
7. If installed, remove the internal USB drive. To locate the internal USB connector, see "System board
components (on page 11)."
8. Remove the front panel/drive cage assembly (on page 24).
9. Remove the M.2 SSD module.

IMPORTANT: Replacing the system board battery resets the system ROM to its default
configuration. After replacing the battery, reconfigure the system through UEFI System
Utilities.
