Replacing 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. The batteries or flash power modules must be installed on top of the air baffle.

Important

• The battery must recharge for at least 6 hours under normal operating conditions. To protect your data, the ServeRAID controller firmware changes the write policy to write-through until the battery unit is sufficiently charged. When the battery unit is charged, the ServeRAID controller firmware changes the write policy to write-back.
• For brevity, in this documentation the Intelligent Battery Backup Unit (iBBU) is often referred to as the battery.

To install a RAID adapter battery or flash power module in the server, complete the following steps:

1. Read the safety information that begins on Safety and Installation guidelines.
2. Turn off the server and peripheral devices and disconnect all power cords and external devices.
3. Remove the cover (see Removing the cover).
4. Remove the cover (see Removing the cover).
5. Push the tab to open the cover on top of the air baffle.

6. Connect one end of the cable to the ServeRAID memory module.
7. Route the battery or flash power module cable along the chassis.
   Attention

   Make sure that the cable is not pinched and does not cover any connectors or obstruct any components on the system board.
8. Install the battery or flash power module on top of the air baffle.
   1. Align the battery or flash power module 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.
