Hard Disk Drives; Scsi Id Assignment - NEC EXPRESS5800/120Rc-2 Service Manual

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.
If you are adding or removing a SCSI hard disk device, consider the following:
Do not hot swap a single-ended disk drive into an LVD-disk-
drive only system for it may cause data corruption. The only
way a single-ended disk drive can be used with an all LVD-
disk-drive system is by first powering down the system,
installing the single-ended disk drive, and then powering the
system back up.
Note:
LVD-disk-drive system causes all the drives to operate in the
non-LVD mode, thereby reducing performance.

SCSI ID Assignment

Your system contains a hard disk drive cage containing one SAF-TE controller
and slots to hold a maximum of five hard disk drives. The hard disk SCSI
address assignments for drives in the drive cage are shown in Figure 4-30 and
Table 4-2.
