Removal and replacement procedures 65
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 25).
2. Remove all power:
a. Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
3. Extend the server from the rack (on page 25).
4. Remove the access panel (on page 29).
5. Remove the SPI board (on page 31).
6. 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 UEFI System Utilities.
IMPORTANT: To avoid a mismatch between boot modes, HP recommends setting system
maintenance switch 7 to the same BIOS boot mode the server is deployed in. Otherwise, the
storage controller may not recognize the OS installed on the storage media.
For more information, see "System Maintenance Switch (on page 78)."
To replace the component, reverse the removal procedure.
For more information about battery replacement or proper disposal, contact an authorized reseller or an
authorized service provider.
