3. Attach the drive end of the cable to Port A on the tape drive.
If you are using a SAS fanout cable, attach one mini-SAS connector to the port on each tape
drive. The unused ends of the SAS fanout cable are single channel and not suitable for use
with disk arrays. Use the other ends to connect additional tape drives, or coil and secure
them to the rack to minimize stress on the connectors.
NOTE: Each tape drive uses one channel and the cable recommended for use with the
library maps each of the four channels from the HBA to one channel on the drive end.
You can plug any of the four drive connectors into any tape drive.
TIP: Mini-SAS connectors are keyed. Do not force a mini-SAS connector into the tape
drive’s port because they might be keyed differently.
NOTE: SAS signal rates require clean connections between the HBA and tape drive. Do not
use adapters or converters between the HBA and the tape drive. For reliable operation, use a
maximum SAS cable length of 6 meters.
Connecting the parallel SCSI cable
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. Hewlett Packard Enterprise 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.
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.
