RAID upgrade kit
The BCM200 main unit and the BCM400 main unit (standard) can contain a redundant array of
independent disks (RAID). The RAID upgrade kits have a single hard disk (mirror) and RAID
controller card. Use your current hard disk (from the single disk system) as the primary hard disk.
When the RAID upgrade is installed, the data from the primary hard disk is written to the mirror
hard disk. The dual hard disk configuration provides one-fault tolerance capability.
