Installing a ServeRAID SAS controller battery on the remote battery
tray
Note: For brevity, in this documentation the Intelligent Battery Backup Unit (iBBU)
is often referred to as the battery.
When you install any ServeRAID SAS controller that comes with batteries, it is
sometimes necessary to install the batteries in another location in the server to
prevent the batteries from overheating. The batteries must be installed near the fan
cage.
To install a ServeRAID SAS controller battery in the server, complete the following
steps:
Note: If you are installing ServeRAID-M5100 Series 512 MB cache RAID 5
upgrade that comes with a battery, you must install the battery in ServeRAID SAS
controller remote battery retention instead (see "Installing an optional ServeRAID
SAS controller battery holder" on the Problem Determination and Service Guide).
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 40.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 28).
3. Remove the cover (see “Removing the cover” on page 54).
4. Connect one end of the battery cable to the ServeRAID SAS controller battery
connector.
5. Route the remote battery 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.
6. Install the battery near the fan cage:
a. Align the battery cable connector with the slot on the battery holder. Place
the battery into the battery holder and make sure that the battery holder
engages the battery securely.
