Thank you for purchasing the LSI MegaRAID LiON (lithium
ion) intelligent Battery Backup Unit 05 (iBBU05). The iBBU05
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 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
iBBU05 on the following RAID controllers:
•
MegaRAID SAS 8704ELP
•
MegaRAID SAS 8708ELP
•
MegaRAID SAS 8888ELP
Please take a few minutes to read this guide before you
install the iBBU05. For more information about any topic
covered in this guide, 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.
You can connect the iBBU05 directly to the MegaRAID SAS
8704ELP and SAS 8708ELP RAID controllers.
The iBBU05 does not mount directly to the MegaRAID SAS
8888ELP RAID controller. Instead, you can use the supplied
12-inch cable to connect the iBBU05 to the RAID controller.
The iBBU05 is mounted inside the chassis within 10 inches
of the controller.
Note:
The LSI part number for the daughtercard is
25125.
Figure 1
shows the top view and the bottom view of the
iBBU05, the M2.50-0.45 x 5mm screws, and the 6mm
standoffs. (The “top” side is the side that you can see after
you install the iBBU05 on the RAID controller.) The iBBU05
combines a battery pack with a daughtercard.

If the SAS 8704ELP or SAS 8708ELP RAID controller is
already installed in a computer, follow these steps to remove
it before you install the iBBU05.
Step 1
Shut down the computer, turn off the power, and
unplug the power cords.
Electrostatic discharge can damage the iBBU05
and the MegaRAID SAS RAID controller. Make
sure that you install the iBBU05 at an ESD-safe
workstation that meets the requirements of EIA-
625 – “Requirements For Handling Electrostatic
Discharge Sensitive Devices.” When you install
the iBBU05, follow the ESD-recommended
practices in the latest revision of IPC-A-610.
