Tandberg Data VXA-320 (VXA-3) manual Install the Tape Drive

INSTALLING THE TAPE DRIVE

4.Obtain the necessary cables and terminator — The tape drive connects to the SCSI bus using a cable with a high-density,68-pin male connector. This cable must meet the guidelines in “SCSI Cable Requirements,” beginning on page 41. If the tape drive is the last device on the SCSI bus, you will need to install an LVD/SE terminator at the physical end of the bus.

5.Do not exceed SCSI bus length restrictions— The maximum allowable length of an LVD SCSI bus is 12 meters (39 feet) if you have more than two devices on the bus. Make sure the SCSI bus attached to the tape drive does not exceed this length. To determine the length of the bus:

a.Add together the lengths of all external SCSI cables attaching devices on the bus. External devices are those connected outside of the server’s enclosure.

b.Add together the lengths of all SCSI cables attaching internal devices on the bus. Internal devices are those installed within the server’s enclosure.

c.Add together the lengths of all internal cabling for all other SCSI devices on the bus. Refer to the individual product documentation for cable length information.

6.Make sure the SCSI bus is properly terminated— You must install an LVD or LVD/SE multimode terminator on the device at the physical end of the SCSI bus. If the tape drive is at the physical end of the SCSI bus, you must install the required terminator on one of the tape drive’s SCSI connectors.

If there are additional devices on the SCSI bus, ensure that only the device at the physical end of the bus is terminated.

Install the Tape Drive

1.Power down the host computer system.

Turn off all devices attached to the computer to which you plan to connect the tape drive, then turn off the computer. Disconnect all power cables.

2.Set the SCSI ID.

The tape drive is shipped with a SCSI ID of 11. If another device on the SCSI bus is already configured with this SCSI ID, you will need to change the tape drive’s SCSI ID. To change the default ID, press the + and – tabs above and below the SCSI ID indicator until the desired SCSI ID appears. See Figure 2-6.

3.Connect the SCSI cable.

a.Ensure that the cable complies with the SCSI-3 specification and has a 68-pin high-density male connector. See Table 6-5for cable specifications.

Caution	Do not use a noncompliant SCSI cable; it will degrade VXA-320performance and
	can cause random, nonreproducible errors. See Table 6-5for cable specifications.
