5.7 Replacing the Backup Battery on the Server Board
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 wrong. Contact your Kontron sales representative for a list of approved
devices.
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.
