CHAPTER 2—INSTALLING THE AUTOLOADER

Do not connect single-ended SCSI devices. Although single-ended SCSI is compatible with the autoloader’s LVD SCSI interface, Exabyte does not support connecting single-ended devices to the SCSI bus attached to the autoloader.

Do not connect the autoloader to a RAID controller. The autoloader will not operated if it is 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 autoloader does not exceed this length. To determine the length of the bus:

a.Add together the lengths of all external SCSI cables on the bus.

b.Add 64 centimeters (25.2 inches) for the internal cable length used by the autoloader and its tape drive.

c.Add the internal cable lengths for any other SCSI devices on the bus.

Make sure the SCSI bus is properly terminated. You must install a terminator on the device at the physical end of the SCSI bus.


! 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 Operation (Tape drive fails with sporadic
	errors) on page 107 for failure symptoms associated with using
	the wrong terminator.

Autoloader is last device on SCSI bus—If the autoloader terminates the SCSI bus, you must install the required terminator on one of the autoloader’s SCSI connectors.

Autoloader is not last device on SCSI bus—If there are additional devices on the SCSI bus, ensure that only the device at the physical end of the bus is terminated.

MAKING THE SCSI CONNECTIONS

To connect the autoloader to SCSI:

1.Make sure that the autoloader is powered off.

2.Power off the host computer and any peripheral devices on the SCSI bus.
