Installing the LSIiBBU08 Unit
2.5.3 Connecting the LSIiBBU08 Remotely to the RAID Controller
The following sections describe the three methods you can use to connect the LSIiBBU08 unit remotely to your
MegaRAID SAS RAID controller using the supplied 12-in., 20-pin cable (sold separately in a Remote Battery Kit).
 Connect a 12-in. cable between a remote LSIiBBU08 unit and the remote BBU connector on your MegaRAID
controller. Reinstall the RAID controller, and mount the LSIiBBU08 unit on the system chassis or motherboard. See
Section 2.5.4, Connecting the Remote LSIiBBU08 Unit to the BBU Connector on the RAID Controller , on page 63 .
 Connect a 12-in. cable between a remote LSIiBBU08 unit and a board-to-board adapter card on the RAID
controller. Reinstall the RAID controller, and mount the LSIiBBU08 unit on the system chassis or motherboard. See
Section 2.5.5, Connecting a Remote LSIiBBU08 Unit on the System Chassis to a Board-to-Board Cable Adapter
Card on the RAID Controller
, on page 66 .
 Connect a 12-in. cable between an LSIiBBU08 unit that is installed on a remote mount board and a
board-to-board adapter card on the RAID controller. Reinstall the RAID controller, and install the remote mount
board. See
Section 2.5.5.5, Installing the Remote Mount Board in the Host Computer , on page 70 .
The procedures in this section show how to connect the LSIiBBU08 unit remotely to the MegaRAID SAS 9280-8i RAID
controller. You can connect the LSIiBBU08 unit in the same way to the other MegaRAID SAS RAID controllers that use
this iBBU unit.
2.5.4 Connecting the Remote LSIiBBU08 Unit to the BBU Connector on the RAID Controller
This section describes how to connect the LSIiBBU08 unit remotely to the BBU connector on the MegaRAID SAS
9280-8e RAID controller.
To connect the remote LSIiBBU08 unit to the BBU connector on the RAID controller, perform the following tasks
in order:
1. Remove the controller from the computer. See Section 2.5.4.1, Removing the RAID Controller from the Computer .
2. Mount the LSIiBBU08 unit to the chassis.
3. Connect the controller to the remote LSIiBBU08 unit using the 12-in., 20-pin cable and the BBU connector on the
RAID controller (the LSIiBBU08 unit must be mounted inside the chassis within 10 in. of the controller). See
Section 2.5.4.2, Connecting the Cable between the RAID Controller and the Remote LSIiBBU08 Unit .
4. Reinstall the controller. See Section 2.5.4.3, Reinstalling the RAID Controller on the Motherboard , on page 65 .
NOTE Because server and workstation chassis vary from vendor to vendor,
there is no standard mounting option that is compatible with the
various system configurations. Therefore, the LSIiBBU08 battery kit, in
combination with the Remote Battery Kit, includes the battery,
daughter card, cable, and standoff, which enable authorized resellers
and chassis manufacturers to customize the location of the remote
battery to provide the most flexibility within various environments.
2.5.4.1 Removing the RAID Controller from the Computer
Follow these steps to remove the RAID controller from the computer.
1. Turn off the power, and unplug the power cords.
2. Ground yourself, and make sure that the system is grounded.
3. Remove the cover from the computer according to the instructions in the system user’s manual to allow access to
the controller.
4. Unplug all cables from the controller, remove the screw that attaches the bracket to the computer chassis, and
carefully remove the controller from the slot.
5. Place the controller on a flat, clean, static-free surface, and continue with the next procedure.
