5. If these pre-configured addresses will not be unique on a bus, you must change the SCSI ID of
one or more tape drives.
To change the SCSI ID:
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 for any drives that must have a different SCSI ID.
For the MSL2024, see “Changing the SCSI address — parallel SCSI devices (Configuration>
Change Drive)” (page 110). For the MSL4048, MSL8048, or MSL8096, see “Changing the
drive configuration (Configuration > Drives)” (page 134).
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 “Changing the drive configuration” (page 85).
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 46 (page 51)).

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: The host bus adapter should be Low Voltage Differential Signaling (LVDS). A
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.
