Replacing the Battery
Before performing the following procedure, read “Safety Notices” on page xi.
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 429.
On a Model 6E4, open the bezel door.
2. Shut down the system as described in either “Stopping the System without an HMC Attached” on
page 424, “Stopping the System with an HMC Attached and AIX Installed” on page 424, or “Stopping
the System with an HMC Attached and Linux Installed” on page 425.
3. Remove the service access cover as described in “Service Access Cover Removal (Model 6C4)” on
page 431 or “Service Access Cover Removal (Model 6E4)” on page 436.
4. Remove the front bezel as described in “Front Bezel Removal (Model 6C4)” on page 442 or “Front
Bezel Removal (Model 6E4)” on page 443.
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 Removal” on page 466. Note the
location of each media drive removed.
6. Remove the media device 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, removes 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.
