Termination:
If the ValueLoader is the only SCSI device (other than
the SCSI host adapter) on the selected SCSI bus, it must be
terminated. Likewise, if the ValueLoader is physically the last SCSI
device on the SCSI bus, it must be terminated. Likewise, if the
ValueLoader is physically the last SCSI device on the SCSI bus, it
must be terminated. Only the devices physically at the beginning and
end of the SCSI bus should be terminated. Refer to the manuals
supplied with the other devices on the SCSI bus for termination on
enabling or disabling termination on those devices.
To terminate the ValueLoader, locate the terminator in the
accessories package and press it firmly into either of the two SCSI
connectors on the back panel of the ValueLoader. Secure the
terminator by tightening the finger-screws until snug. The supplied
terminator is “dual mode” and will work on both LVD and SE SCSI
buses. A green LED on the terminator indicates that the unit is
attached to a SCSI bus running in LVD mode. A red LED on the
terminator indicates that the unit is attached to a SCSI bus running in
SE mode. If the LED is not on, check all SCSI and power connections
and confirm that the unit is attached to a valid SCSI bus.
•
Compatibility:
Ensure that the ValueLoader and tape drive are
compatible with the SCSI host adapter and backup application you
plan to use. For a list of compatible SCSI adapters and application
software, check with your SCSI host adapter manufacturer, backup
application vendor, or the Quantum support web site at
www.Quantum.com
.
•
SCSI Host Adapter Installation:
Verify that you have installed your
SCSI host adapter correctly. Refer to the manual that came with your
SCSI host adapter for installation and troubleshooting instructions.
Pay particular attention to any steps describing the settings of various
jumpers and/or switches on the host adapter or, on newer adapters,
the setup application for the adapter. Make sure that the host adapter
is properly seated in the motherboard slot, and the operating system
correctly detects the host adapter. Make sure that the proper device
driver is installed for the SCSI host adapter.
•
Backup Application Installation:
Refer to the documentation included
with your backup application for instructions on how to verify
proper installation. Most backup software packages require an
additional module to communicate with the ValueLoader robotics.
