SCSI INTERFACE REQUIREMENTS

SCSI Terminator Requirements

If the internal tape drive is the last device on the SCSI bus, you must terminate the bus by installing an pass-through LVD/SE terminator on the tape drive’s SCSI connector. Or, if there is an unused connector at the end of the SCSI cable, you can terminate the bus there. If the cable provided with your adapter has a built-in terminator, do not add another terminator to the bus.

Note: If you will be installing the tape drive in an enclosure and using an external terminator, you must install a high-quality active LVD terminator that complies with the SCSI-3 specification.

EXTERNAL TAPE DRIVE

This section describes the cable, connector, and terminator requirements for the external LVD SCSI tape drive.

SCSI Cable Requirements

For the external tape drive, select a cable that complies with the SCSI-3 specification and meets the requirements listed in Table 6-5.

Table 6-5SCSI cable requirements

Specification

Requirement

 

 

Connector type

68-pin male, high-density, shielded, SCSI-3 compliant

 

 

Maximum lengtha

12 meters (39 feet)b

aThe maximum length of 12 meters only applies to an LVD SCSI bus. If a single-ended device is connected anywhere on the bus, all devices on the bus operate in single-ended mode. When operating in single-ended mode, the maximum allowable bus length is 3 meters (9.8 feet), terminator to terminator. Exceeding the maximum cable length will result in unstable and unpredictable operation.

bIf only two devices are attached to an LVD bus in a point-to-point configuration, the maximum allowable cable length is 25 meters (82 feet).

SCSI Terminator Requirements

If the external tape drive is the last device on the SCSI bus, you must terminate the bus by installing a high-quality active LVD/SE terminator that complies with the SCSI-3 specification on one of the tape drive’s SCSI connectors.
