Sun Microsystems L40 Choosing SCSI HVD or LVD

Standard Installation Procedure

1-12 Revision L 96053

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.
