ValueLoader LTO Tape Autoloader User Manual 49
• 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 the either of the
two SCSI connectors on the rear 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 is compatible with
the SCSI host adapter and backup application you plan to use.
For a list of compatible SCSI adapters and application software
packages, check with your SCSI host adapter manufacturer,
backup application vendor, or our Web site.
•
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 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.
