LSI MegaRAID iBBU01 Quick Installation Manual

MegaRAID
Backup Unit
Quick Installation Guide
Thank you for purchasing the LSI MegaRAID LiON (lithium
ion) intelligent Battery Backup Unit 01 (LSIiBBU01). The
LSIiBBU01 is designed for use on MegaRAID SAS RAID
controllers. It protects the integrity of the cached data on a
MegaRAID controller for up to 72 hours in the event of a
complete AC power failure or a brief power outage.
LSI provides a family of MegaRAID intelligent battery backup
units (iBBUs) for use with its high-performance MegaRAID
RAID controllers. The LSI MegaRAID iBBUs provide an
inexpensive alternative to using an uninterruptible power
supply and a second level of fault tolerance when used in
conjunction with an uninterruptible power supply.
This quick installation guide explains how to install the
MegaRAID LSIiBBU01 for use with the following controllers:
• MegaRAID SAS 8308ELP
• MegaRAID SAS 8344ELP
• MegaRAID SAS 84016E
• MegaRAID SATA 300-8ELP
• MegaRAID SATA 300-8XLP
Please take a few minutes to read this Quick Installation
Guide before you install the iBBU. For more information
about the LSIiBBU01, refer to the Intelligent Battery Backup
Units for 1078-based MegaRAID Products User's Guide on
your MegaRAID Universal Software Suite CD.

An intelligent BBU has built-in functionality to charge the
battery pack automatically and to communicate battery
status information such as voltage, temperature, and current,
to the host computer system.
The LSIiBBU01 does not connect directly to the MegaRAID
controllers. Instead, it uses the supplied 20-pin, 12-inch
cable to connect remotely to a controller. The LSIiBBU01
must be mounted inside the chassis within 10 inches of the
RAID controller.
Because server and workstation chassis vary from vendor to
vendor, there is no standard mounting option that is
compatible with the various system configurations. The
LSIiBBU01 battery kit contains only the battery and the
cable, allowing VAR's and chassis manufacturers to
customize the location of the remote battery to provide the
most flexibility within various environments.
The LSIiBBU01 combines a battery pack with a
daughtercard. Figure 1 shows the top view and the bottom

see after you install the iBBU on the RAID controller.)
Note: The LSI part number for the daughtercard is
25126.

connect it remotely to the SAS 8344ELP RAID controller.
Step 1 Ground yourself, and remove the LSIiBBU01 from
the package.
Step 2 Use the three Phillips-head screws that are
provided to secure the LSIiBBU01 to the
motherboard or the server chassis.
