SCSI Cables and Guidelines
All workstation models use the following three areas for connecting mass
storage SCSI devices:
■
Internally with hard drives in the removable hard drive cage
■
Internally with storage devices in the front panel drive bays
■
Externally with external storage devices.
The workstation has an integrated Dual Wide-Ultra SCSI controller with two
independent channels, channel 1 and channel 2. Channel 1 has one internal SCSI
connector on the system board. Channel 2 has two connectors, one internal SCSI
connector on the system board and one external SCSI connector on the rear
panel of the workstation. In addition to the Dual Channel capability described
above, some models will contain a Wide-Ultra2 SCSI controller; thus providing
a third channel (channel 3). Channel 3 is located in the second PCI slot from the
right.
SCSI Cables
The workstation ships standard with a 5-device Wide-Ultra SCSI cable or Wide-
Ultra2 SCSI cable. One end of this cable connects to the internal channel 1
Wide-Ultra SCSI or Wide-Ultra2 SCSI connector, and the other end (first
device connector) of the cable connects to the hard drive(s) in the removable
hard drive cage. The cable has five connectors to handle up to five SCSI
devices, a maximum of three in the removable hard drive cage and two in the
front drive bay area. As an optional configuration, you may want to use an
industry-standard, 2-device Wide-Ultra SCSI or Wide-Ultra2 SCSI cable for
connecting the internal channel 2 Wide-Ultra SCSI or Wide-Utra2 SCSI
connector on the system board to SCSI devices installed in the front drive bays.
