Battery Replacement
System Board Battery Replacement
When the server blade 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. Access the internal server blade components. Refer to the “Accessing Internal
Server Blade Components” section in Chapter 3, “Server Blade Setup.”
