5.6 Replacing the CMOS 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 (for
example, the date and time) stored in CMOS RAM in the RTC may be lost or corrupted.
Contact your Kontron sales representative or dealer for a list of approved replacement batteries.
Caution: Before replacing the battery, you must first take the server out of service, turn off all
peripheral devices connected to the system, turn off the system by pressing the power
button, and unplug the power cord from the system or wall outlet.
WARNING
Danger of explosion if battery is replaced incorrectly. Replace only with the same or equivalent type
recommended by the equipment manufacturer. Discard used batteries according to manufacturer's
instructions.
