Replacing the Back up Battery
The lithium battery on the server board powers the real time clock (RTC) for up to 10 years in
the absence of 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.
