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.
To install a RAID adapter battery in the server, complete the following steps:
Note: The 2.5-inch hard disk drive server model supports up to two RAID adapter batteries or flash
power modules, while the 3.5-inch hard disk drive server model supports only one RAID adapter battery
or flash power module.
Step 1. Read the safety information that begins on "Safety" on page v and "Installation guidelines" on
page 116.
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 119).
Step 4. Install the ServeRAID adapter on the system board (see "Replacing a ServeRAID SAS/SATA
controller" on page 185) or install the ServeRAID adapter on the riser card and install the riser-card
assembly in the server (see "Replacing an adapter" on page 178 and "Replacing a PCI riser-card
assembly" on page 172).
Step 5. Connect one end of the cable to the RAID adapter memory module.
Step 6. Route the cable along the chassis.
Note: The cable routing is different between 2.5-inch and 3.5-inch hard disk drive server models.
