Preparing the Host System

At this point you need to refer to your software installation guide for instructions on installing the backup/
controlling software for the autoloader onto the host system. Read through the
and Connection Guidelines

SCSI Host System Adapter and Connection Guidelines

If necessary, install a SCSI host system adapter, software, and compatible driver(s). Refer to the manuals
for the host system and SCSI host system adapter for detailed instructions. In addition, follow these general
guidelines:
• Make sure that your backup application supports the SCSI host system adapter.
Depending on the server configuration, you may need to change the SCSI IDs of the autoloader
(see Viewing or Changing the SCSI
• Make sure that the host server system has an open expansion slot.
• If the host server system is connected to a network, check with the system administrator before
turning off power.
• Use proper procedures to prevent electrostatic discharge (ESD). Use wrist-grounding straps and
anti-static mats when handling internal components.
The LVD host system bus adapter is recommended. A single ended SCSI host
NOTE:
system bus adapter does work, but can severely degrade performance. Also, if
there are any SE devices on the same SCSI bus, the entire SCSI bus
negotiates down to SE speed and can severely degrade performance.

Autoloader SCSI Connections

The autoloader incorporates a wide SCSI-2, Low-Voltage Differential (LVD) SCSI bus, but may also be
attached to a Single-Ended (SE) SCSI bus. Make sure your SCSI host system adapter or controller supports
these standards. If you connect the autoloader to the SE SCSI bus or if there are SE devices attached to
the same SCSI bus, the autoloader's performance is limited to the maximum data transfer speed and
maximum cable lengths of the SE bus.
The autoloader is NOT compatible with a standard differential (Diff) or High-Voltage Differential (HVD) SCSI
bus. The autoloader is compatible with a narrow (50-pin) SCSI bus using a 68-pin to 50-pin adapter that
terminates the unused 18 pins. These adapters are sometimes labeled high-byte termination.

Connecting SCSI and Power Cables

The following describes how to connect the SCSI and power cables.
The autoloader is an Ultra-2 Wide device. Only use cables and terminators
NOTE:
specified for Ultra-2 use or labeled as MultiMode.

SCSI devices. Remove the power cables from the server and all attached accessories.

IDs).
Failure to remove the power cables from these devices could
result in damage to the autoloader.
