LSI MegaRAID iBBU01 User manual

Thank you for purchasing the LSI MegaRAID LiON (lithium
ion) intelligent Battery Backup Unit 01 (iBBU01). The iBBU01
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 iBBU01 on 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 iBBU01, 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 iBBU01 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 iBBU01 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 iBBU01 combines a battery pack with a daughtercard.
Figure 1 shows the top view and the bottom view of the
iBBU01, 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 iBBU01 on the MegaRAID
SAS 8344ELP RAID Controller
This section documents the installation of the iBBU01 on the
MegaRAID SAS 8344ELP RAID controller. You can install
the iBBU on the other RAID controllers in a similar manner.
Follow these steps to install the iBBU01 remotely to the SAS
8344ELP RAID controller.
Step 1 Ground yourself, and remove the iBBU01 from
the package.
Step 2 Use the three Phillips-head screws that are
provided to secure the iBBU01 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 iBBU01.

Step 4 Connect the 12-inch cable from the J5 connector
on the iBBU01 to the J11 battery backup
connector on the backside of the SAS 8344ELP
RAID controller, as shown in Figure 2.
On the iBBU01, pin 1 of J5 is marked by a white
dot. Pin 1 of the cable should be connected to the
white dot on J5.
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
Warning: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.
