Replacing the Backup Battery
The lithium battery on the server board powers the 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.
Danger of explosion if battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the
equipment manufacturer. Discard used batteries according to
manufacturer's instructions.
