3 - Connect SCSI Cable (Power Off)
Make certain that both ends of the SCSI cable are terminated and that all devices in
between the ends are non-terminated. The SCSI connector on the TEK933 board is
terminated.
Attach one end of the SCSI cable to the J2 SCSI 50-pin connector. Make sure line 1 of
the cable is matched with pin 1 of connector J2.
Attach the other end to your SCSI device, making sure line 1 is matched with pin 1 on
your device.
You must also install a cable from your power supply to your SCSI device.
4 - Follow Specific Device Installation Instructions (Power On)
Follow installation instructions provided with your SCSI peripheral device to install it
in the host.
Each device being installed must be assigned a unique identifier called a
SCSI Target ID. The lower the ID, the lower the priority level of the
device in the SCSI subsystem. The host adapter is usually assigned the
highest priority level (i.e. 7). Table 11-1 lists common SCSI Target IDs.
