Installing or Swapping a Hard Disk Drive in a Hot-swap Bay

This procedure describes installing a new drive or swapping out a faulty drive
from one of the five hot-swap SCSI disk drive bays. The SCSI drives use the
industry standard 80-pin Single Connector Attachment (SCA) connector. Each
drive must be installed in a drive carrier.
Note:
representative or dealer.
!
If installing new drives, follow an installation scheme starting with the
Bay 1. Fill the bays right to left. See Figure 4-30.
!
If your system includes a RAID controller, hard disk drives may be
removed or installed without powering down the system; if your system
is connected to a non-RAID SCSI host controller, you must power down
the system before hard disk drives may be removed and installed.
!
If an individual SCSI drive fault LED (amber light) is on steadily, this
indicates that the drive has been flagged as faulty by the RAID host
controller. Follow the procedure described in this section to remove the
faulty drive and swap in a good one.
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.
D
rive manufacturers caution against moving a disk drive
that is still spinning because of possible damage to the drive.
