Hard Disk Drives - NEC EXPRESS5800/180Ra-7 User Manual

Hard Disk Drives

The following sections provide procedures for installing a disk drive, removing
a disk drive, or swapping out a faulty disk drive from one of the hot-swap drive
bays. The 3 1/2-inch SCSI drives must use the industry standard 80-pin Single
Connector Attachment (SCA) connector. Each drive must be installed in a
carrier.
Note:
representative or dealer.
" If installing new drives, follow an installation scheme starting with the
bottom left drive. Fill the bays left to right.
" If an individual SCSI drive fault LED (yellow light) is on steadily, this
indicates that the drive has been flagged as faulty. Follow the procedure
described in this section to remove the faulty drive and swap in a good
one.
Note:
This is one of the few system procedures that is safe to do
with the system power left on. This is true only if a
Redundant Array of Independent Disks (RAID) controller
module is installed and only for the drive/carrier assemblies
in the hot-swap bays, not for drives in any other bays.
Note:
parts. This system can withstand normal levels of
environmental ESD while you are hot-swapping SCSI hard
drives. However, we recommend that you do all procedures
in this chapter only at an ESD workstation or provide some
ESD protection by wearing an antistatic wrist strap attached
to chassis ground (any unpainted metal surface) on your
system when handling parts.
