Touring the Chassis

Rear View

These major components are located on the back of the SCSIBox 2 (see
Figure 2-3):

SCSI In (A/B)

provides a 68-pin SCSI-2 differential connector.

Note:

Each SCSI box provides two SCSI In connectors for disk striping and

increased I/O throughput.

SCSI Out (A/B)

provides connection for SCSI termination or a daisy-chain
connection to another SCSI box.
