SCSI INTERFACE REQUIREMENTS

INTERNAL TAPE DRIVE

This section describes the cable, connector, and terminator requirements for the internal High-density, 68-pin LVD SCSI tape drive.

SCSI Cable Requirements

The cable connected to the tape drive SCSI connector must meet the SCSI-3 specifications listed in Table 6-3.

Caution Using a noncompliant SCSI cable will degrade VXA-320performance and can cause random, nonreproducible errors. Tandberg Data recommends using shielded cables.

Table 6-3SCSI cable and connector specifications

Specification

Requirement

 

 

General

Wide, LVD SCSI-3

 

 

Connector

High-density, 68-pin, male

 

 

Maximum lengtha

12 meters (39.2 feet)

Stub length

ƒ No greater than 0.1 meters should be used off the mainline connection within any

 

connected equipment.

 

ƒ The stub length within the tape drive is less than 2.5 centimeters (1 inch).

 

 

Impedance

Between 90 and 140 ohms.

 

An impedance of greater than 100 ohms is recommended. To minimize

 

discontinuities and signal reflections, all cables on the bus should have the same

 

impedance.

 

 

Conductor size

28 AWG (0.08097 mm2)

 

A minimum of 28 AWG will minimize noise effects and ensure proper distribution of

 

terminator power.

 

 

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.
