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.
Warning: 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.
Advarsel: Lithiumbatteri - Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med
batteri af samme fabrikat og type. Levér det brugte batteri tilbage til leverandøren.
Advarsel: Lithiumbatteri - Eksplosjonsfare. Ved utskifting benyttes kun batteri som anbefalt av
