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.

Read the safety information that begins on Safety and Installation guidelines.
Turn off the server and peripheral devices and disconnect all power cords and external devices.
Remove the cover (see Removing the cover).
Install the ServeRAID adapter on the system board (see Replacing a ServeRAID SAS/SATA controller) or install the ServeRAID adapter on the riser card and install the riser-card assembly in the server (see Replacing an adapter and Replacing a PCI riser-card assembly).
Connect one end of the cable to the RAID adapter memory module.
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.

Attention
Ensure that the battery/flash-power-module cable is routed straightly near the power-supply cage, otherwise the cable might get overheated and the system board might get damaged.
Attention
Make sure that the cable is not pinched and does not cover any connectors or obstruct any components on the system board.
Remove any cable covering or obstructing the holder before opening the holder.
Install the battery or flash power module.
Steps for installing the RAID adapter battery or flash power module for 2.5-inch hard disk drive server models.
1. Release the retention clip in the open position.
2. Align the cable connector with the slot on the holder. Place the battery or flash power module into the holder and make sure that the holder engages the battery or flash power module securely.
  Note
  The positioning of the battery or flash power module depends on the type of the battery or flash power module that you install.
3. Connect the other end of the cable to the battery or flash power module.
4. Press down on the retention clip until it snaps in place to hold the battery or flash power module firmly in place.
