the holes in the chassis.

Battery
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.

Caution: Press the riser card straight down into the slot. Tipping it in the slot while installing it
may damage the riser card or board slot.
