Battery

Caution – Before touching or replacing any component inside the Sun Fire V60x
and Sun Fire V65x servers, disconnect all external cables and follow the instructions
in "Safety: Before You Remove the Cover" on page 5-2 and "Removing and
Replacing the Cover" on page 5-3. Always place the server on a grounded ESD pad
and wear a properly grounded antistatic wrist strap.
The lithium battery on the server board powers the real time clock (RTC) for up to 10
years in the absence of power. A low battery condition is stored in the System Event
Log (SEL).
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 replacement
batteries.
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 battery:
1. Before proceeding, record your custom BIOS settings.
2. Observe the safety and ESD precautions at the beginning of this chapter.
3. Open the chassis and locate the battery (on the main board, near the left front
corner).
