Multi-Unit Library System Operation

Powering Up

All Library units should be powered up at the same time through the storage cabinet supplied
power, or the master unit (top) should be powered up last if the Library units are powered up
individually.

Connecting a Multi-Unit Library System

The following procedure explains how to set the SCSI ID and SCSI host connections:
1. For maximum performance, connect only 2 AIT-2 drives to each SCSI host adapter.
2. For nominal performance, you can connect 3 AIT-2 drives per host.
3. Set the SCSI IDs through the master unit front panel dependent on the SCSI host adapter
drive ratio.
4. On the master unit, the Library will take up a SCSI ID (default is 0).
5. AIT drives on different SCSI host adapters can have the same ID.
NOTE: If you use only two drives per SCSI host adapter, leaving the default setting will work provided
there is no conflict with any other devices.
