3. Select your backup software application — To obtain information about
which backup software applications work with the tape drive, visit
Tandberg Data’s web site www.tandberg.com You can install the backup
software application on the host computer before or after you install the
tape drive. However, if you install the backup application software first, you
may need to reconfigure it for use with 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.
Set the SCSI ID and connect the SCSI cable
1. Power down the computer system.
Turn off all devices attached to the computer in which you plan to install the
tape drive, then turn off the computer. Disconnect all power cables.
!
Important Do not connect the tape drive to a RAID controller. The tape drive
will not operate properly if it is connected to a RAID controller.
Although the tape drive’s High-density LVD SCSI interface is
compatible with both single-ended and narrow SCSI buses, to
avoid performance issues Tandberg Data does not recommend
using the tape drive on either of these buses.
If any single-ended device, including a single-ended terminator is
attached to the LVD bus, the result is that all devices on that bus
will run in single-ended mode. Tandberg Data recommends that
you do not use the tape drive on a bus with a single-ended device.
Caution
Do not connect the tape drive to an HVD controller. Doing so may damage the
tape drive.
