Appendix C System Battery; Battery Replacement - HP ProLiant DL585 User Manual

The servers have memory devices that require a battery to retain stored information.

Battery replacement

When the server no longer automatically displays the correct date and time, you
might need to replace the battery that provides power to the real-time clock. Under
normal use, battery life is usually about five to 10 years. Use an HP 220-mAh
lithium, 3-V replacement battery.
To install a new battery:
1. Power down the server. Refer to "Powering down the server" in Chapter 2,
"Server operations."
2. Extend the server from the rack. Refer to "Extending the server from the rack" in
Chapter 2, "Server operations."
3. Remove the access panel. Refer to "Removing the access panel" in Chapter 2,
"Server operations."
4. Locate the battery on the system board.
NOTE: It might be necessary to remove some PCI-X expansion boards to gain access to the
battery.
