4.10.11 Replacement of Battery of DIMM for On-board RAID
Before replacing the battery or a DIMM, make sure that the +2.5 VDC output lamp on the I/O
Board is off if the AC cables are disconnected from the Server.
If the lamp is on, turn on the DC power of the Server once and run the POST before the
replacement. Then turn off the power of the Server again, disconnect the AC cables, and make sure
that +2.5 VDC output lamp on the I/O Board is off.
Before the +2.5 VDC output lamp can be checked, the rear access cover must be removed. The
lamp is installed below the power cage.
Do not use any unauthorized batteries and DIMMs provided for other units.
The defined battery life is two years or 500 charge cycles. If a battery is charged for more than 500,
it is determined that its life has come. Then replace the battery.
