Requirements for SCSI Bus Termination

If the tape drive is the last device on the SCSI bus, it must be terminated. As described in this section, the termination requirements for the tape drive depend on whether it uses a single-ended or differential SCSI configuration.

Terminators for Single-Ended Configuration

The single-ended SCSI configuration includes three single in-line package (SIP) resistor terminators (R-packs). They can be left in place if the tape drive terminates the SCSI bus or removed if the tape drive does not terminate the SCSI bus or if external termination is used.

If necessary, the single-ended tape drive can be terminated externally. To ensure that the tape drive performs to specification, Exabyte recommends a Methode Electronics, Inc. dataMate® DM103-02-0 single-ended external terminator.

Terminators for Differential Configuration

The differential SCSI configuration of the tape drive does not include internal terminators. If a differential tape drive terminates the SCSI bus, it must be terminated externally. To ensure that the tape drive performs to specification, Exabyte recommends a Methode Electronics, Inc. dataMate DM103-01-0 differential external terminator.
