MegaRAID® LSIiBBU09 Intelligent Battery Backup Unit
Thank you for purchasing the LSI® MegaRAID® LSIiBBU09 intelligent battery backup unit (iBBU). Before you install and
connect the LSIiBBU09 unit, please take a few minutes to read this quick installation guide. This guide explains how to
connect the LSIiBBU09 unit to your MegaRAID SAS RAID controller.
If you need more information about any topic covered in this guide, refer to the related documents on your MegaRAID
Universal Software Suite CD.
Product Overview
The LSI MegaRAID LSIiBBU09 product is an iBBU based on Lithium ion (LiON) battery cell technology. The LSIiBBU09
unit protects the integrity of the cached data on a MegaRAID RAID controller for up to 48 hours (depending on the
derated retention time selected) in case of a complete AC power failure or a brief power outage. You can connect the
LSIiBBU09 unit either directly or remotely to your RAID controller, depending on which RAID controller you have.
LSI provides a family of MegaRAID iBBUs for use with its high-performance MegaRAID RAID controllers. The LSI
MegaRAID iBBUs provide an inexpensive alternative to using an uninterruptible power supply (UPS) and a second
level of fault tolerance when used with a UPS.
Direct Connection
The LSIiBBU09 unit connects directly to the following MegaRAID SAS RAID controllers:
 MegaRAID SAS 9266-4i RAID controller
 MegaRAID SAS 9266-8i RAID controller
See Attaching a LSIiBBU09 Unit Directly to a MegaRAID SAS 9266 RAID Controller for instructions on how to attach the
LSIiBBU09 unit directly to these controllers.
Remote Connection
The LSIiBBU09 unit connects remotely to the following MegaRAID SAS RAID controllers:
 MegaRAID SAS 9265-8i RAID controller
 MegaRAID SAS 9266-4i RAID controller
 MegaRAID SAS 9266-8i RAID controller
 MegaRAID SAS 9285-8e RAID controller
The LSIiBBU09 unit connects remotely by cable to the MegaRAID SAS 9266-4i RAID controller and the MegaRAID SAS
9266-8i RAID controller.
The LSIiBBU09 unit connects remotely to a TMM02® transportable memory module that is attached to the MegaRAID
SAS 9265-8i RAID controller and the MegaRAID SAS 9285-8e RAID controller. You have two ways to connect the
remote LSIiBBU09 unit by cable to a TMM02 transportable memory module on these two controllers:
 Connect the LSIiBBU09 unit by cable to the TMM02 module on the RAID controller and then mount the LSIiBBU09
unit on the system chassis (see
Connecting a Remote LSIiBBU09 Unit on the System Chassis to a TMM02 Module
on a RAID Controller on page 11 for the instructions).
