Replacing the Back up Battery
The lithium battery on the server board powers the real time clock (RTC) in the absence of AC power. When the battery starts to weaken, it loses voltage, and the server settings stored in CMOS RAM in the RTC (for example, the date and time) may be wrong. Contact your customer service representative or dealer for a list of approved devices.
To replace the battery:
1Before proceeding, record your custom BIOS settings.
2Observe the safety and ESD precautions at the beginning of this chapter.
3Open the chassis and locate the battery.
4Push the upper end of the metal retainer away from the battery- the battery pops up.
5Remove the battery from its socket.
6Dispose of the battery according to local ordinance.
7Remove the new lithium battery from its package.
8Being careful to observe the correct polarity, lay the battery in the socket.
9Push the battery
10Close the chassis.
11Run Setup to restore the configuration settings to the RTC.
12Restore your custom BIOS settings.
