4-38 Upgrading Your System
Hard Disk Drives
The following paragraphs provide procedures for installing an additional disk drive,
removing a disk drive, or swapping out a faulty disk drive from one of the three hot-
swap drive cages. 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:
To order a carrier, contact your sales representative or
dealer.
If installing new drives, follow an installation scheme starting with the bottom
left drive. Fill the cages left to right.
If an individual SCSI drive fault LED (yellow light) is on steadily, this indicates
that the drive below it has been flagged as faulty. Follow the procedure described
in this section to remove the faulty drive and swap in a good one.
Note:
Swap SCSI drives without turning off power. 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 cages,
not for drives in any
other bays.
Note:
ESD can damage disk drives, boards, and other 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.
