MegaRAID® iBBU01 LiON Battery 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.

Overview of the Intelligent Battery

Backup Unit

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

view of the LSIiBBU01, 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 iBBU on the RAID controller.)

Note

: The LSI part number for the daughtercard is

25126.

Installing the LSIiBBU01 and Connecting

it Remotely to a MegaRAID RAID

Controller

This section documents how to install the LSIiBBU01 and
connect it remotely to the MegaRAID SAS 8344ELP RAID
controller. You can connect the LSIiBBU01 to the other RAID
controllers in a similar manner.

Perform the following steps to install the LSIiBBU01 and
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.

Step 3 Insert the battery pack harness connector at the

end of the battery pack harness into the J1
connector on the bottom side of the LSIiBBU01.

Step 4 Connect the cable from the J5 connector on the

LSIiBBU01 to the J11 battery backup connector
on the backside of the SAS 8344ELP RAID
controller, as shown in Figure 2.

The LSIiBBU01 does not connect directly to the
MegaRAID controllers. Instead, it uses the
supplied 20-pin, 10-inch cable to connect to a
controller. There are black triangles on the
connectors to help you install them properly.
Insert the cable connectors into the controller
connector and the iBBU connector so that the
black triangles are aligned, as shown in the
example in Figure 2.

Note

: The cable connector is polarized and can be

inserted into the J11 board battery connector only
if the rails on the harness connector align with the
slots on the J11 connector. Do not force the
cable into the 20-pin in-line connector. The cable
end should insert into the connector with minimal
resistance.

Disposing of Battery Backup Units

If the iBBU is damaged in any way, toxic
chemicals may be released.

The material in the battery pack contains heavy metals that
can contaminate the environment. Federal, state, and local
regulations prohibit the disposal of rechargeable batteries in
public landfills. Be sure to recycle the old battery packs
properly. Comply with all applicable battery disposal and
hazardous material handling laws and regulations in the
country or other jurisdiction where you are using the iBBU.

There is danger of an explosion if the battery is
incorrectly replaced. Replace it only with the
same or equivalent type recommended by the
manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
