Hot-Swapping a SCSI Hard Drive
Hot-Swapping Bays
Two 3.5-inch hot-swapping bays provide space for 3.5 inches X 1 inches (or
1.6 inches) single connector attachment (SCA2) SCSI hard disk drives. You can
install up to two industry-standard wide/ultra or wide/ultra2 SCA-type hard disk
drives in these bays.
The power supply fans provide cooling for the hot swap drives. A system with
two power supplies is capable of cooling most drives that would be installed
into the system. However, drives that dissipate a large amount of power might
require three power supplies to ensure proper cooling. See the product
specifications to determine if the particular drive to be installed needs the
additional cooling provided by a third power supply.
Carriers for 3.5-inch wide 1-inch or 1.6-inch height drives allow easy hot-
swapping of drives in and out of these bays without shutting down the server.
You can easily set up RAID applications if you install a Redundant Array of
Inexpensive Disks (RAID) controller board on the PHP I/O carrier, RAID
software, and SCSI hard disk drives in the hot-swapping bays.
SCSI SCA Hard Disk Drives
The server supports a variety of single-ended SCSI SCA-type hard disk drives.
As shipped from the supplier, the server might not contain any drives. Contact
your sales representative or dealer for a list of approved drives that can be
installed in the server.
Mounting a SCSI SCA Hard Disk Drive in a Carrier
1.
Remove the 3.5-inch hard disk drive from the protective wrapper, and place
it on an antistatic surface.
2.
Record the model and serial numbers of the drive in your equipment log.
3.
Orient the drive carrier so that the handle is toward your left and the metal
EMI/ESD fingers are toward your right. See Figure 4-2. Orient the drive so
that:
!
The drive’s label faces away from the carrier heatsink, toward the carrier
fingers
!
The drive’s connector faces away from the carrier handle
!
CAUTION
Be careful not to bend or damage the carrier’s metal fingers
as you attach the drive to the carrier.
