SCSI Bus Termination

The Model B50 has an Ultra SCSI bus which can support internal and external SCSI devices. However, each controller on these SCSI busses must have a unique SCSI ID. The external SCSI busses must be properly terminated to ensure SCSI signal integrity.

For directions on setting the SCSI ID on each device, consult the documentation for

that device, as well as the Adapters, Devices, and Cable Information for Multiple Bus Systems.

Note:

Internal SCSI IDs cannot be used on the external SCSI connector (J38). The

 

internal SCSI IDs are as follows:
