Overview 1. Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification Overview This document describes the key hardware components, firmware, and software utilities for the Intel® RAID Smart Battery AXXRSBBU6. The Smart Battery AXXRSBBU6 ensures data integrity for the RAID solution by ensuring that the data passing through the cache is written to the hard drives. The Smart Battery supports RAID controllers that use a standard 128 MB or 256 MB DDR2 DIMM.
Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification Overview This method of writing data carries a risk. Cached data on the RAID controller can be lost if the AC power fails before it is written to the storage device. The Smart Battery mitigates this risk by providing battery power to the RAID controller if AC power is lost. The Smart Battery monitors the voltage level of the DRAM modules on the RAID controller.

Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification 2.5 Hardware Smart Refresh Circuit Board The Intel® RAID Smart Battery AXXRSBBU6 is based on the Texas Instruments bq2060A SBS v1.1-compliant Gas Gauge IC. The key features of the SBS v1.1 IC are: Provides accurate measurement of available charge Supports SBS Smart Battery Data Specification v1.
Hardware 2.6 Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification Connector Cable A 5-pin connector cable connects the battery pack to the Smart Battery circuit board. Table 4. Connector Pin-outs Pin 1 2.
Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification Hardware parameters. The relearn cycle takes up to 24 hours to fully-discharge and recharge the battery pack. After the relearn cycle is completed, information from the battery accurately provides the state of charge, capacity, and other parameters. These parameters determine the health of the battery. The relearn cycle can be set at a user-definable interval. The default is a one-month (30day) interval.

Intel® RAID Smart Battery AXXRSBBU6 Technical Product Specification 4. Software 4.1 Intel® RAID BIOS Console 2 Software The system BIOS loads the RAID option ROM that is resident on the RAID controller flash. Run this utility by pressing + when prompted during POST. The option ROM checks for the presence of the battery and informs the user if the battery is missing or not fully charged. The RAID BIOS Console Utility can be used to monitor charge cycle count and voltage levels. 4.
