Hard Disk Drives

Your system supports a variety of SCSI hard disk drives. The SCSI drives must use the industry standard 80-pin Single Connector Attachment (SCA) connector. Contact your sales representative or dealer for a list of approved devices. The internal hard disk drives are located in the SCSI Disk Drive Bays (A).

If you are adding or removing a SCSI hard disk device, consider the following:

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.

nThe onboard SCSI controller supports single-ended drives. If a RAID controller board is installed it supports Low Voltage Differential (LVD) disks. The hard disk SCSI address assignment is:
