Connecting a Remote LSIiBBU07 Unit to a MegaRAID SAS RAID Controller
Connecting a Remote LSIiBBU07 Unit to a MegaRAID SAS RAID Controller
The following sections describe the three methods you can use to connect a LSIiBBU07 unit remotely to your
MegaRAID SAS RAID controller using the 12-in., 20-pin cable (sold separately in a Remote Battery Kit). The methods
are as follows:
1. Connect a 12-in. cable between a remote LSIiBBU07 unit and the remote BBU connector on your RAID controller.
Reinstall the RAID controller, and mount the LSIiBBU07 unit on the system chassis or motherboard. See
Connecting a Remote LSIiBBU07 Unit to the BBU Connector on the RAID Controller .
2. Connect a 12-in. cable between a remote LSIiBBU07 unit and a board-to-board cable adapter card on the RAID
controller. Reinstall the RAID controller, and mount the LSIiBBU07 unit on the system chassis or motherboard. See
Connecting a Remote LSIiBBU07 Unit on the System Chassis to a Board-to-Board Cable Adapter Card on a RAID
Controller
on page 11 .
3. Connect a 12-in. cable between an LSIiBBU07 unit that is on a remote mount board and a board-to-board cable
adapter card on the RAID controller. Reinstall the RAID controller, and then install the remote mount board. See
Connecting an LSIiBBU07 Unit from a Remote Mount Board to a Board-to-Board Adapter Card on a RAID
Controller
on page 15 .
The procedures in each section show how to connect the LSIiBBU07 unit remotely to a MegaRAID SAS RAID controller.
You can connect the LSIiBBU07 unit in the same way to the other MegaRAID controllers that support each method of
connection. See
Product Overview on page 3 for information about which RAID controllers support each method of
remote connection.
For information about the BBU connectors on the RAID controllers, refer to the MegaRAID 6Gb/s SAS RAID Controllers
User Guide on the MegaRAID Universal Software Suite CD.
Connecting a Remote LSIiBBU07 Unit to the BBU Connector on the RAID Controller
This section describes how to connect a remote LSIiBBU07 unit to the remote BBU connector on the SAS 9280-4i4e
RAID controller. You can connect the LSIiBBU07 unit in the same way to the other MegaRAID controllers that support
this method of connection.
Perform the following tasks.
1. Remove the controller from the computer. For this procedure, see Removing the RAID Controller from the
Computer on page 9 .
2. Mount the LSIiBBU07 unit to the chassis.
3. Connect the controller to the remote LSIiBBU07 unit using the 12-in., 20-pin cable and the BBU connector on the
RAID controller (the LSIiBBU07 unit must be mounted inside the chassis within 10 in. of the controller). For this
procedure, see
Connecting the Remote LSIiBBU07 Unit on page 9 .
4. Reinstall the controller. For this procedure, see Reinstalling the RAID Controller on the Motherboard on page 10 .
NOTE Ground yourself, and disconnect the power cords from the system before you remove the cover. Also,
make sure that the system is grounded.
NOTE Because server and workstation chassis vary from vendor to vendor, no standard mounting option is
compatible with the various system configurations. Therefore, the LSIiBBU07 battery kit contains only the
battery, daughter card, 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.
