2.4.5 Connecting a Remote LSIiBBU07 to a Daughter Card on the RAID Controller
This section describes how to connect the remote LSIiBBU07 unit to a daughter card that is on the MegaRAID
SAS 8888EM2 RAID controller.
To connect the remote LSIiBBU07 unit to a daughter card 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.

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.
