To terminate the autoloader, locate the terminator in the accessories

package and press it firmly into either of the two SCSI connectors on the

rear panel of the autoloader. Secure the terminator by tightening the

finger-screws until snug. The supplied terminator is “dual mode” and will

work on both Low-Voltage Differential (LVD) and Single Ended (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 autoloader is 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 HP support website at

■

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. 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. Many backup software

packages require an additional module to communicate with the

autoloader robotics.

■

Device Driver Installation:

If applicable, make sure that the proper ISV and/or autoloader driver is

installed. For more information, see
