Replacing a RAID adapter battery or flash power module

Use this information to replace a RAID adapter battery or flash power module.
About this task
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:
Procedure
1. Read the safety information that begins on "Safety" on page vii and
"Installation guidelines" on page 33.
2. Turn off the server and peripheral devices and disconnect all power cords and
external devices.
3. Remove the cover (see "Removing the cover" on page 36).
4. Install the ServeRAID adapter on the system board (see "Replacing a
ServeRAID SAS/SATA controller" on page 254) or install the ServeRAID
adapter on the riser card and install the riser-card assembly in the server (see
"Replacing an adapter" on page 250).
5. Connect one end of the cable to the RAID adapter memory module.
6. Route the cable along the chassis.
