LSI LSIBBU07 Battery Back Up

Remote Battery Mounting Application Note
Standard BBU Mounting Provisions
The BBU06 and BBU07 Battery Backup Options consist of a BBU Control Module which is a small daughter PC board assembly and a Battery Pack assembly.
The BBU control module included in these accessory kits can be mounted directly on LSI 3Gb/s and 6Gb/s RAID Controllers, respectively, in four and eight
port configurations. You can mount these accessories off the controller (remote) as well to reduce airflow constraints in dense systems. For 16i and 24i
controllers it is required to use the remote mount option (LSI00260) described below.
All LSI 6Gb SATA + SAS products use the same BBU Control Module and Battery Pack model BBU07. The BBU Control Module can be mounted on the 6Gb/s
RAID Controller (4 and 8 port models only), but it is possible to remotely mount the Battery Pack as well.
The BBU Control Module is electrically connected via a 20 pin connector and held in place with standoffs and screws. The Battery Pack is snapped in
place and retained by two latches that engage slots on the BBU control module and is electrically connected to the daughter board by a pigtail with a
5 pin connector.
Alternate Locations for Battery Pack
The battery pack can be attached onto a Battery Mounting PCB (BBU-BRACKET-04) that is secured to the back of the enclosure by a standard PC mounting
bracket. The card is mounted on a Full Height mounting bracket and an optional Low Profile bracket is also included as part of the kit. Both brackets are
“vented” to allow maximum cooling air flow in the vicinity of the battery. The remote mounted BBU connects to the RAID controller using an extension
cable kit (LSI00260) that supports locations up to 12” from the controller.
