Replacing the Backup Battery
The lithium battery on the serverboard 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: There is a danger of explosion if the battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the equipment manufacturer.
Discard used batteries according to the manufacturer’s instructions.
To replace the backup battery, use the following steps:
1. Locate the battery on the server board.
2. Gently press the metal clip as shown to release the battery.
See A Figure 4-28.
3. Remove the battery from the plastic socket.
See B in Figure 4-28.
