Installing a RAID Controller Board
Use this procedure to install a RAID controller board.
1. Install the RAID controller board into any PCI slot on the system board. See
"Installing an Option Board" earlier in this chapter.
2. Cable the RAID controller board as described below (see "System Cabling"
in Appendix A):
!
Remove the end of the SCSI interface cable that is plugged into the Ultra-
160/M SCSI connector on the system board.
!
Reinstall the end of the SCSI interface cable just removed into the
Channel 0 connector on the RAID board.
Hard Disk Drives
Your system supports a variety of SCSI hard disk drives. The SCSI drives must

internal hard disk drives are located in the SCSI Disk Drive Bays (A).

CAUTION
Do not hot swap a non-LVD-disk-drive into a LVD-disk-drive
only system for it may cause data corruption. The only way a
non-LVD-disk-drive can be used with an all LVD-disk-drive
system is by first powering down the system, installing the
non-LVD-disk-drive, and then powering the system back up.
Note:
Installing a non-LVD-disk-drive into an all LVD-
disk-drive system causes all the drives to operate in the non-
LVD mode.
