Hard Disk Drives - NEC EXPRESS5800/120Ld Service Manual

Hard Disk Drives

The system supports a variety of SCSI hard disk drives installed in the system's
hard disk drive bay. The SCSI hard disk drive bay in the system is one of two
types: a standard SCSI disk drive bay or a hot-swap SCSI disk drive bay.
Refer to Figure 4-18 to identify the type of hard disk drive bay in the system. In
each example 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 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
