Installing the mirrored disk controller

If you upgrade your system from a single-disk system to a mirrored disk system, you will need to
install the RAID board as well as a second hard disk.

The RAID board is installed beside the media bay module housing in the BCM1000. Refer to

Figure 112

.

You can upgrade both 2.5 and 2.0 hardware to have mirrored capability. You do not require a
redundant power supply and redundant fans to support this feature. If you are upgrading either
system, you must be running 2.5 FP1 software or higher and have at least 256 RAM of memory
installed. If you need to install more memory, refer to

“Replacing memory” on page 287

.
