Appendix G System Battery; Server Blade Battery Replacement - Compaq BL10e - HP ProLiant - 512 MB RAM Setup And Installation Manual

Each ProLiant BL e-Class server blade has one memory device that requires a battery
for retaining stored information.

Server Blade Battery Replacement

When 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 usually about 5 to 10 years. Use an HP 540-mAh, lithium, 3-V
replacement battery (spare P/N 234556-001).
To install a new battery:
1. Power down the server blade. See the "Powering Down a Server Blade" section
in Chapter 3.
2. Remove the server blade from the enclosure. See the "Removing a Server Blade"
section in Chapter 3.
