10. Attach the cover over the operator panel.
11. Attach the door with the two hinge pins, inserting the top pin first.
Choosing SCSI HVD or LVD
Your library interface is hardware configured as either high voltage differential (HVD) or
low voltage differential (LVD). The HVD interface allows longer cable lengths, but
throughput is slower than LVD. The LVD interface restricts cable lengths, but provides
faster throughput.
CAUTION:
Potential equipment damage: Do not mix LVD and HVD operation on the
same bus.
SCSI Cable Restrictions
The library and drives accept only SCSI Type-3 connectors. If you use SCSI Type-1 or -2
connectors, you must use a SCSI Type-1- or SCSI Type-2-to-SCSI Type-3 adapter.
Note: If you are connecting the library or drives to an LVD SCSI bus, the cable can be
no longer than 12 m (39.4 ft).
Each interface requires a unique terminator.
The following table lists restrictions for SCSI connections.
