CHAPTER 2—INSTALLING THE LIBRARY
GUIDELINES FOR CONNECTING TO SCSI
Keep these guidelines in mind as you plan your SCSI connections:
 Do not connect to an inadequate host bus adapter.
 Do not connect single-ended SCSI devices. Although single-ended SCSI is
compatible with the tape drive’s LVD SCSI interface, Tandberg Data
Corporation does not support connecting single-ended devices to the SCSI
bus attached to the tape drives.
 Do not connect the tape drives to a RAID controller. The library will not
operate if the tape drives are connected to a RAID controller.
 Do not exceed SCSI bus length restrictions. The maximum allowable length
of an LVD SCSI bus is 12 meters (39 feet) if you have more than two devices
on the bus. Make sure the SCSI bus attached to the tape drives does not
exceed this length.
 Make sure the SCSI bus is properly terminated. You must install a
terminator on the device at the physical end of the SCSI bus. If one of the
tape drives in the library terminates the SCSI bus, you must install the
required terminator on one of the tape drive’s SCSI connectors.
If there are additional devices on the SCSI bus, ensure that only the device
at the physical end of the bus is terminated.

Both LTO-2 and LTO-3 SCSI tape drives are Ultra 160 SCSI
devices and require a minimum Ultra 160 non-RAID SCSI host
bus adapter card.

! Important
Both LTO-2 and LTO-3 SCSI tape drives require an Ultra 3 or
LVD 160 terminator to function properly on the SCSI bus. An
inadequate terminator will result in various SCSI bus issues,
including bus hangs and Read/Write failures. See “Tape Drive
Fails with Sporadic Errors” on page 201.
