MegaRAID® iBBU06 Intelligent
Battery Backup Unit
Quick Installation Guide
The LSI MegaRAID LSIiBBU06 is an intelligent battery
backup unit (iBBU) that 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.
This quick installation guide explains how to install the
iBBU06 on the MegaRAID SAS 8708EM2 RAID controller.
It also explains how to connect the iBBU06 remotely.
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.
Figure 1 shows the front view and the rear view of the
iBBU06. The front view is the side that you can see after you
install the iBBU06 on the RAID controller. Note that iBBU06
combines a battery pack with a daughtercard. iBBU06 uses
screws and standoffs to connect to the controller.

Installing the iBBU06 on the SAS
8708EM2 RAID Controller
Electrostatic discharge can damage the iBBU06
and the MegaRAID SAS RAID controller. Make
sure that you install the iBBU06 at an ESD-safe
workstation that meets the requirements of EIA625 – “Requirements For Handling Electrostatic
Discharge Sensitive Devices.” When you install
the iBBU06, follow the ESD-recommended
practices in the latest revision of IPC-A-610.
Follow these steps to install the iBBU06 on the SAS
8708EM2 RAID controller. The battery backup unit is
installed on the front side of the controller.
Step 1 Ground yourself, and remove the iBBU06
daughter card from the package.
There is danger of an explosion if the battery is
incorrectly replaced. Replace the battery only
with the same or equivalent type recommended
by the manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
Step 2 Insert the battery pack harness connector at the
end of the colored wires into the 5-pin J4
connector on the rear side of the iBBU06.
Step 3 Place the iBBU06 front-side-up on a flat, clean,
static-free surface.
Step 4 Place the RAID controller front-side up on a flat,
clean, static-free surface.
Step 5 Hold the iBBU06 daughtercard so that the battery
side is up and the J5 connector lines up with the
J10 BBU connector on the RAID controller, as
shown in Figure 2.

Step 6 Carefully press the iBBU06 onto the RAID
controller so that the two connectors are firmly
joined.
Step 7 Secure the iBBU06 to the RAID controller with the
screws and the standoffs in the three screwholes.
The standoffs are threaded at both ends, and a
screw goes into each end.
Step 8 Use the Phillips-head screws that are provided to
secure the iBBU06 to the RAID controller.
Step 1 Ground yourself, and remove the iBBU06 from
the package.
Step 2 Use the three Phillips-head screws that are
provided to secure the iBBU06 to the
motherboard or the server chassis.
Step 3 Insert the battery pack harness connector at the
end of the colored wires into the J4 connector on
the rear side of the iBBU06.
Step 4 Connect the J2 connector on the iBBU06 to the
J10 battery backup connector of the RAID
controller, as shown in Figure 3.
The iBBU06 does not connect directly to the MegaRAID
controllers. Instead, it uses the supplied 20-pin, 10-inch
cable to connect the iBBU06 to the RAID 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 Figure 3.

RAID Controller
Center the screwdriver carefully to avoid stripping
the screw heads. Do not over-tighten the screws.
Step 9 Install the RAID controller in a PCI Express slot
in the computer.
Connecting the iBBU06 Remotely to the
8708EM2 RAID Controller
You can connect the iBB06 remotely to the 8708EM2 RAID
controller. Use the supplied 20-pin cable to connect the
iBBU06 to a RAID controller.
Because server chassis design and workstation chassis
design vary from vendor to vendor, there is no standard
mounting option that is compatible with the various system
configurations.
Therefore, the iBBU06 battery kit contains only the battery
and the cable, allowing value-added reseller’s (VAR) and
chassis manufacturers to customize the location of the
remote battery to provide the most flexibility within various
environments.
Follow these steps to install the iBBU06 remotely to the
RAID controller.
