3.2.2 Connecting a SCSI Array

The SCSI Diamond-VT uses a VHDCI connector and SCSI cables to connect to a host. It automatically detects the type of Host Interface Card it is using without any intervention.

To connect the SCSI Diamond-VT

1Insert a SCSI VHDCI connector into the Host Interface Card in the back of the Diamond-VT.

or connect a cable between the second connector and the next device on the SCSI bus.

3The SCSI Host Interface Card has a rotary binary-coded hex switch which allows you to set the SCSI ID of the HIC. Be sure the selected ID is different from all other SCSI devices on the bus.

2If the SCSI Diamond-VT is the last device on the bus, you must attach a VHDCI terminator to one connector of the SCSI Host Interface Card

Exhibit 3.2-1 SCSI cable options.

Note

If slower devices are connected on the same SCSI bus as the Ultra 160 Diamond-VT, the bus communicates at the rate of the slowest device.
