Warnings
Heed safety instructions: Before working with your server product, whether you are
using this guide or any other resource as a reference, pay close attention to the safety
instructions. You must adhere to the assembly instructions in this guide to ensure and
maintain compliance with existing product certifications and approvals. Use only the
described, regulated components specified in this guide. Use of other products /
components will void the UL listing and other regulatory approvals of the product and
will most likely result in noncompliance with product regulations in the region(s) in which
the product is sold.
System power on/off: The power button DOES NOT turn off the system AC power. To
remove power from system, you must unplug the AC power cord from the wall outlet.
Make sure the AC power cord is unplugged before you open the chassis, add, or remove
any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the server and
disconnect the power cord, telecommunications systems, networks, and modems attached
to the server before opening it. Otherwise, personal injury or equipment damage
can result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives,
boards, and other parts. We recommend that you perform all procedures in this chapter
only at an ESD workstation. If one is not available, provide some ESD protection by
wearing an antistatic wrist strap attached to chassis ground any unpainted metal surface on
your server when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to ESD. Hold boards only by their edges. After removing a board from its
protective wrapper or from the server, place the board component side up on a grounded,
static free surface. Use a conductive foam pad if available but not the board wrapper. Do
not slide board over any surface.
Installing or removing jumpers: A jumper is a small plastic encased conductor that slips
over two jumper pins. Some jumpers have a small tab on top that you can grip with your
fingertips or with a pair of fine needle nosed pliers. If your jumpers do not have such a tab,
take care when using needle nosed pliers to remove or install a jumper; grip the narrow
sides of the jumper with the pliers, never the wide sides. Gripping the wide sides can
damage the contacts inside the jumper, causing intermittent problems with the function
controlled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool
you use to remove a jumper, or you may bend or break the pins on the board.

1About the Intel®RAID Smart Battery
AXXRSBBU8
Intel®RAID (Redundant Array of Inexpensive Disks) Controllers and Intel®Integrated
RAID Modules provide reliability, high performance, and fault-tolerant disk subsystem
management. A complete fault-tolerant strategy requires protection of all data, including
the unwritten cached data in the RAM cache. If power is lost, the data in the RAM cache
is lost. To avoid data loss, a battery can be added to supply power to the RAID RAM
during an AC power outage or if the AC power cord is removed.
A battery backup unit (BBU) protects the integrity of the cached data on Intel®RAID
Controllers by providing backup power if there is a complete AC power failure or a brief
power outage. The Intel®RAID Smart Battery Backup Unit provides an inexpensive
alternative to using an uninterruptible power supply (UPS) or it can act as a second level
of fault tolerance when used with a UPS.
The cache memory available on Intel®RAID controllers can improve the overall system
performance. Writing data to the controller's cache memory is much faster than writing it
to a storage device. Write operations appear to complete very quickly at the software
application level. The Intel®RAID Controller writes the cached data to the storage device
when system activity is low or when the cache is getting full. The risk of using write-back
cache is that the cached data can be lost if the AC power fails before it is written to the
storage device. This risk factor is eliminated when the Intel®RAID Controller has a
BBU installed.
The Intel®RAID Smart Battery Backup Unit monitors the voltage level of the DRAM
modules installed on the Intel®RAID Controller. If the voltage drops below a predefined
level, the battery backup module switches the memory power source from the controller to
the battery pack attached to the Intel®RAID Smart Battery Backup Unit. As long as the
voltage level stays below the predefined value, the battery backup module provides power
for memory. When the voltage level returns to an acceptable level, the module switches
the power source back to the Intel®RAID Controller, and all pending writes to storage
devices are completed without losing any data.
The battery backup module 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 Intel®RAID Smart Battery AXXRSBBU8 is a smart battery backup module and uses
lithium-ion (Li-Ion) battery technology. It is compatible with a backup auxiliary power
source. The battery is charged automatically.

Remote Extender Board (REB)
The REB component is a small daughter card that mounts directly to the base controller
through the board-to-board connector J2 and is secured by one screw. It provides a 20-pin
battery connector J1 for remote battery installation support for base controllers that do not
have a 20-pin connector on the controller. The REB is included in the RAID controller
product kit.
Figure 2. Remote Extender Board
Remote Battery Connecting Cables
A 20 inch 20-pin cable is provided in the battery kit to remotely connect the Intel®RAID
Smart Battery AXXRSBBU8 to the RAID controller, or to a REB which is mounted on
the RAID controller. Intel recommends mounting the battery remotely from the RAID
controller when possible to provide additional cooling.

Note: Controllers that can directly connect to 20-inch cable already has a cable connector on it,
which is same as the J1 connector as shown in Figure 2 (Remote Extender Board).
Important Pre-installation Considerations
Warning: Always ground yourself and/or use a ground strap before touching the RAID controller or
the Intel®RAID Smart Battery AXXRSBBU8. Perform all installation work at an ESD-
safe workstation. Use an ESD-safe Phillips* screwdriver set to a maximum torque of 2.25
inch-pounds, and be sure the screwdriver is centered in the screw to avoid damaging the
screw head. If you exceed the maximum torque specification, you may damage the board,
connectors, or screws, and you will void the warranty of the board.
The batteries in the Intel®RAID Smart Battery AXXRSBBU8 must charge for at least six
hours during fast charge, under normal operating conditions.
To protect your data, Intel recommends that you set the RAID Controller Write Policy to
write-through until the battery unit is fully charged. When the battery unit is charged, you
can change the Write Policy to write-back to take advantage of the performance
improvements of data caching.
The maximum ambient temperature for the battery pack is shown in the following tables.

6Intel®RAID Smart Battery AXXRSBBU8 User’s Guide
Note: The temperature of the battery pack is generally 15-20 degrees higher than the ambient
temperature during fast charge. Therefore, to complete the fast charge cycle, ambient
temperature should be less than 55° C. If the ambient temperature exceeds 45° C, the fast
charge cycle will terminate prematurely, thus preventing the battery pack from reaching a
fully charged state. Intel recommends mounting the battery remotely from the RAID
controller when possible to provide additional cooling.
