If you are instructed to return the RAID adapter battery or flash power module, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to you.
Replacing a RAID adapter battery or flash power module
Use this information to replace a RAID adapter battery or flash power module.
When you install any RAID adapter that comes with batteries or flash power modules, it is sometimes
necessary to install the batteries or flash power modules in another location in the server to prevent the
batteries or flash power modules from overheating. Depending on your server model, a battery or flash
power module must be installed remotely near the optical drive cage or the backplane. The 2.5-inch server
models support up to two batteries or flash power modules.
To install a RAID adapter battery in the server, complete the following steps:
Step 1.
Read the safety information that begins on “Safety” on page v and “Installation guidelines”
on page 31.
Step 2.
Turn off the server and peripheral devices and disconnect all power cords and external devices.
Step 3.
Remove the cover (see “Removing the cover” on page 189).
Step 4.
Install the ServeRAID adapter on the system board (see “Replacing a ServeRAID SAS/SATA
controller” on page 231) or install the ServeRAID adapter on the riser card and install the riser-card
assembly in the server (see “Replacing an adapter” on page 226).
Step 5.
Connect one end of the cable to the RAID adapter memory module.
Step 6.
Route the cable along the chassis.
