v If the 3580 Tape Drive Is One of Multiple Devices On the SCSI Bus: connect the SCSI bus cable to the next device on the bus, move the terminator to the last device on the bus, then issue the host command to resume operation (see Figure 4). The maximum allowable length of your bus cable depends on the type of SCSI host adapter card (LVD/SE or HVD/DIFF) that is installed in your host: - For a host with an LVD/SE SCSI host adapter card, use a cable with a total length of 12 m (39 ft) or less. - For a host with an HVD/DIFF SCSI host adapter card, use a cable with a total length of 25 m (82 ft) or less. To determine whether your host uses an LVD/SE or HVD/DIFF SCSI host adapter card, see "Step 8. Installing the SCSI Host Adapter Card (if required)" on page 10. Attention: Do not mix LVD/SE and HVD/DIFF SCSI host adapters, tape drives, or terminators on the same bus, as they could become damaged. Figure 4.

If the 3580 Tape Drive Is One of Multiple Devices On the SCSI Bus:
connect the SCSI bus cable to the next device on the bus, move the
terminator to the last device on the bus, then issue the host command to
resume operation (see Figure 4). The maximum allowable length of your
bus cable depends on the type of SCSI host adapter card (LVD/SE or
HVD/DIFF) that is installed in your host:
–
For a host with an LVD/SE SCSI host adapter card, use a cable with a
total length of 12 m (39 ft) or less.
–
For a host with an HVD/DIFF SCSI host adapter card, use a cable with
a total length of 25 m (82 ft) or less.
To determine whether your host uses an LVD/SE or HVD/DIFF SCSI host
adapter card, see “Step 8. Installing the SCSI Host Adapter Card (if
required)” on page 10.
Attention:
Do not mix LVD/SE and HVD/DIFF SCSI host adapters, tape
drives, or terminators on the same bus, as they could become damaged.
