Installing the LSIiBBU07 Unit
2.4.3 Connecting the LSIiBBU07 Unit Remotely to the MegaRAID SAS RAID Controller
The following sections describe the three methods you can use to connect the LSIiBBU07 unit remotely to your SAS
RAID controller using the supplied 12-in., 20-pin cable:
 Use the cable to connect the remote LSIiBBU07 unit to the BBU connector on the RAID controller (see
Section 2.4.4, Connecting the Remote LSIiBBU07 Unit to the BBU Connector on the RAID Controller , on page 46 ).
 Use the cable to connect the remote LSIiBBU07 unit to a daughter card that is connected to the BBU connector on
the RAID controller (see
Section 2.4.5, Connecting a Remote LSIiBBU07 to a Daughter Card on the RAID Controller ,
on page 49 ).
 Use the cable to connect a LSIiBBU07 unit on a remote mount board and a board-to-board cable adapter card on
the RAID controller (see
Section 2.4.6, Connecting an LSIiBBU07 Unit from a Remote Mount Board to a
Board-to-Board Adapter Card on a RAID Controller , on page 53 ).
2.4.4 Connecting the Remote LSIiBBU07 Unit to the BBU Connector on the RAID Controller
This section describes how to connect the remote LSIiBBU07 unit to the BBU connector on the MegaRAID
SAS 8888EM2 RAID controller.
To connect the remote LSIiBBU07 unit to the BBU connector on the RAID controller, perform the following tasks.
WARNING Ground yourself, and disconnect the power cords from the system
before you remove the cover. Also, make sure that the system
is grounded.
1. To remove the controller from the computer, see Section 2.4.4.1, Removing the RAID Controller from the
Computer .
2. To connect the remote LSIiBBU07 unit to the BBU connector on the RAID controller using the 12-in., 20-pin cable
(the LSIiBBU07 unit must be mounted inside the chassis within 10 in. of the controller), see
Section 2.4.4.2,
Connecting the Remote LSIiBBU07 Unit .
3. To reinstall the controller, see Section 2.4.4.3, Reinstalling the RAID Controller on the Motherboard , on page 48 .
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 LSIiBBU07 battery kit
contains only the battery, daughtercard, and standoff, which enables
authorized resellers and chassis manufacturers to customize the
location of the remote battery to provide the most flexibility within
various environments.
2.4.4.1 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. Remove the cover from the computer according to the instructions for allowing access to the controller in the
system user’s manual.
3. Ground yourself before you touch 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.
