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.

1 About the Intel

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 Controllers by providing backup power if there is a complete AC power failure or a brief power outage. The Intel 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 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 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 BBU installed.

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 ESDsafe 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.

AXXRSBBU8 Operating temperature of 55°C

Expected hold time 48 hours 12 hours

Service life Up to 1 year Up to 3 years

AXXRSBBU8 Operating temperature of 45°C

Expected hold time 48 hours 12 hours

Service life Up to 3 years Up to 5 years

Intel® RAID Smart Battery AXXRSBBU8 User’s Guide 5

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.
