Connecting The Parallel Scsi Cable (Parallel Scsi Devices Only) - HP BL536A User's & Service Manual

1. Plug the power cord into the power connector on the back panel and then plug the cord into
the power outlet.
2. From the front panel, push the round power button to power on the device.
3. From the front panel, set the new SCSI ID (see
devices (Configuration > Change Drive) (page
4. Power off the device by depressing the power button on the front panel.
TIP: The SCSI ID can also be changed from the RMI Configure: Drive screen once the RMI is
configured. See

Connecting the parallel SCSI cable (parallel SCSI devices only)

NOTE: LTO-3 and LTO-4 tape drives are Ultra 320 SCSI LVD devices. Use only cables and
terminators specified for Ultra 320 or labeled as MultiMode. LTO-2 tape drives are Ultra 160 SCSI
LVD/SE devices; use only cables and terminators specified for Ultra 160 or Ultra 320, or labeled
as MultiMode.
NOTE: For optimal performance, a parallel SCSI tape drive should be the only device on the
bus.
To connect the parallel SCSI cable to the device:
1. HP recommends that the host server be powered off before attaching new devices.
2. Attach one end of the parallel SCSI cable (included in the accessory package) to one of the
connectors on the back panel of the tape drive (see
Figure 17 Attaching the parallel SCSI cable to the tape drive
3. Attach the other end of the parallel SCSI cable to the connector on the parallel SCSI host bus
adapter or to the connector on the previous device on the parallel SCSI bus.
NOTE:
Single-Ended (SE) SCSI host bus adapter works, but severely degrades performance and limits
cable length. If any SE devices are on the same parallel SCSI bus, all of the devices on the
parallel SCSI bus slow to SE speed, which severely degrades performance. Never attach an
LTO-3 or LTO-4 tape drive to an SE SCSI bus.
4. Attach the terminator to the remaining parallel SCSI connector on the back panel of the tape
drive if the Autoloader is the last or only device on the parallel SCSI bus. Otherwise, attach
one end of a parallel SCSI cable to the remaining port and the other end to the next device
on the parallel SCSI bus. Make sure the last device on the parallel SCSI bus is properly
terminated.
IMPORTANT:
have a SCSI terminator unless the tape drive is part of a properly terminated chain. This
includes tape drives without an attached SCSI cable.
