Differential SCSI

According to SCSI-3 ANSI specifications for Differential Ultra Wide SCSI, the total SCSI cable length is 25 meters (984 inches). The internal SCSI bus of the DEU is a Single-ended bus and therefore a conversion is required when interfacing to an external differential SCSI bus.

The DEU supports Differential SCSI by using the Differential Converter Feature card. This card provides the termination and drivers necessary to interface to a differential SCSI bus. The external cable length can be up to a maximum of 25 meters as described by the SCSI-3 ANSI specifications.

A symptom of exceeding the cable limits is a SCSI bus lockup or “freeze.” If you experience a similar problem and are aware of a cabling limit issue, reducing the length of cabling and returning the total length to within the specified limit should resolve any problems.

If you have a cabling issue and require more information, contact your Service Provider for further assistance. Data loss is possible under conditions of SCSI bus lockup.
