Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification 1. Overview Overview This document describes the key hardware components, firmware, and software utility requirements for the Intel® RAID Smart Battery AXXRSBBU7. It provides data integrity for the RAID (Redundant Array of Inexpensive Disks) solution by ensuring that the data passing through the cache is protected during a power outage until written to the hard drives.
Overview Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification 1. J4 Battery Pack Harness Connector 2. J5 Board-to-board Connector 3. J2 Remote BBU Connector 4. Battery Pack Harness Figure 1. Intel® RAID Smart Battery AXXRSBBU7 The battery pack charges automatically and communicates battery status information, such as voltage, temperature, and current to the host computer system.
Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification Overview The Intel® RAID Smart Battery AXXRSBBU7 monitors the voltage level of the DRAM modules on the RAID controller. If the voltage drops below a predefined level, the Smart Battery switches the memory power source from the RAID controller to the battery pack.

Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification During boot loader execution During a RAID firmware boot 2.6.4.2 Hardware Discharging State The battery voltage is drained as part of a relearn cycle. 2.6.4.3 Fully-charged State Battery voltage level is monitored to determine the level of charge. Charging begins when the battery’s sensing logic detects low voltage. Once a new battery is fully charged, a relearn cycle is initiated.
RAID Firmware Interaction 3.
Intel® RAID Smart Battery AXXRSBBU7 Technical Product Specification 4. Software 4.1 Intel® RAID BIOS Console 2 Software The system BIOS loads the RAID option ROM that resides on the Intel® RAID controller flash. To use this utility, press + when prompted during POST (Power-on Self Test). The option ROM checks for the presence of the battery and informs the user if the battery is missing or not fully charged.
