SCSI Cables and Guidelines

All workstation models use three areas for connecting mass storage SCSI devices: internally with hard drive in the removable hard drive cage, internally with storage devices in the front panel drive bays, and externally with external storage devices. The workstation has an integrated Wide-Ultra SCSI controller that has one internal connector on the system board and one external connector on the rear panel.

SCSI Cables

The workstation ships standard with a 5-device Wide-Ultra or Wide Ultra2 SCSI cable that has a terminator on one end. The other end of this cable connects to the internal Wide-Ultra SCSI connector on the system board. The first device connector of the cable connects to the hard drive 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.

Figure 3-41. 5-device Wide-Ultra SCSI cable

NOTE: The SCSI cable included with the workstation may look slightly different than the one pictured.

When installing a Wide Ultra2 SCSI hard drive a Wide Ultra2 SCSI cable (not shown) is required.
