Replacing the hard disk
The BCM1000 for the 2.5 system includes either one or two factory-installed hard disks. You also
can install a second hard disk to a single-disk base unit.
This chapter explains how to change a hard disk, and how to upgrade a single-disk system to a
mirrored system by adding a RAID board and a second hard disk.
Figure 102 provides an overview of the hard disk replacement process.
