SCSI-2 Bus Termination Guidelines

There are certain guidelines to follow when terminating a SCSI-2 bus. These guidelines are:

CAUTION: Unless the SCSI-2 bus is properly terminated, the bus will not operate. Terminators provide impedance matching on SCSI-2 bus signal lines.

The last device connected to the SCSI-2 bus must be terminated with a SCSI-2 terminator. Use a Hewlett-Packard K2291 50-pin low-density bail-lock active terminator or a Hewlett-Packard C2904A high-density thumbscrew active terminator to terminate the last SCSI-2 option device.

Any termination on other devices on the bus must be removed. This includes external termination plugged into a SCSI-2 receptacle on the device, or internal resistor packs. (Refer to peripheral device or system configuration manuals for termination information).
