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."
