4-24 Dissasembly and Reassembly
Installing or Swapping a Hard Disk Drive in a Hot-Swap Bay
This procedure describes installing a new hard disk drive or swapping out a
faulty drive from one of the six hot-swap SCSI disk drive bays. The SCSI drives
must use the industry standard 80-pin Single Connector Attachment (SCA)
connector. Each drive must be installed in a drive carrier.
Note:
To order a disk with a carrier, contact the sales
representative or dealer.
!
If installing new drives, follow an installation scheme starting with the
left-most drive. Fill the bays left-to-right (1 through 6). See Figure 4-19.

If an individual SCSI drive fault LED (yellow light) is on steadily, this
indicates that the drive has been flagged as faulty by the RAID host
controller (See Figure 4-19,A). Follow the procedure described in this
section to remove the faulty drive and swap in a good one.
