A-4 Upgrading Firmware Through CLI
This Command Line Interface (CLI) provides you to configure and manage the 12Gb/s SAS RAID controller
components in Windows, Linux, FreeBSD and more environments. The CLI is useful in environments where a
graphical user interface (GUI) is not available. Through the CLI, you perform firmware upgrade that you can perform
with the McRAID storage manager GUI. The controller has added protocol on the firmware for user to update the
controller firmware package(BIOS, BOOT, FIRM and MBR0) through the utility.
To update the controller firmware, follow the procedure below:
Appendix B
Flash-based Backup Module (AC-SAN-1883FBM)
B-1 Overview
The AC-SAN-1883FBM kit includes the Flash-based module (FBM), and one cable. The FBM features NAND flash
memory and super capacitor technology that provides cache offload capability to protect cached data in case of
system power loss. The module is mounted super-capacitor pack or battery that provides power for the backup of
your data. When the module detects loss of power, the super capacitor keeps parts of the RAID controller active
long enough to allow cache data to be copied to the flash memory. The module attaches directly to the 12 Gb/s SAS
RAID controller by the cable.
B-2 FBM Components
The following figure provides the board layout and connector/jumper of the FBM.
