Replacing the Battery
Before performing the following procedure, read “Safety Notices” on page vii.
CAUTION:
A lithium battery can cause fire, explosion, or severe burn. Do not recharge,
disassemble, heat above 100°C (212°F), solder directly to the cell, incinerate, or
expose cell contents to water. Keep away from children. Replace only with the
part number specified for your system. Use of another battery may present a risk
of fire or explosion.
The battery connector is polarized; do not attempt to reverse polarity.
Dispose of the battery according to local regulations.
To replace the system’s battery, do the following:
1. On a Model 6C4, open the front and rear rack doors and put the system into the
service position as described in “Placing the Model 6C4 into the Service Position”
on page 53.
On a Model 6E4, open the bezel door.
2. Shut down the system as described in “Stopping the System” on page 52.
3. Remove the service access cover as described in “Service Access Cover Removal
(Model 6C4)” on page 55 or “Service Access Cover Removal (Model 6E4)” on
page 57.
4. Remove the front bezel as described in “Front Bezel Removal (Model 6C4)” on
page 61 or “Front Bezel Removal (Model 6E4)” on page 63.
5. Disconnect and label all power and signal cables from the media drives, located in
media bay 1 and media bay 2, then remove the media drives as described in
“Media Drive Removal” on page 100. Note the location of each media drive
removed.
6. Remove the media support shelf by loosening the thumbscrew and grasping the
back edge of the shelf, sliding it back, then lifting it up and out of the system
chassis.
Note: The support leg located on the bottom of the support shelf is used to
deactivate a microswitch. The microswitch is located on the CEC backplane
and when deactivated, cuts off power to many of the components and
connectors located on the CEC backplane. This support shelf must be
correctly seated and secured in position after any new FRU is added to the
system and you perform a system boot.
