This section provides suggestions for solving problems that may occur when
you are installing and operating the autoloader.
Note:
If an error code is displayed on the autoloader’s operator panel, refer to
. If the LEDs on the tape drive are flashing, see

If your autoloader and application software are not communicating after
installation, check the following:
✔
SCSI IDs.
Make sure that the SCSI IDs you selected for the drive and
autoloader are not the same as an ID used by any other SCSI device on that
bus, including the SCSI adapter card. Refer to
for information about
setting the SCSI IDs.
✔
SCSI connectors.
Make sure that all SCSI cables are securely connected at
both ends.
✔
LVD SCSI devices.
Because the autoloader is an LVD device, all other
devices on the SCSI bus should also be LVD. These devices include the
controller cards, cables, terminators, and any other devices on the SCSI bus.
Do not mix LVD and HVD on the same SCSI bus.
Note:
Although LVD SCSI is compatible with single-ended SCSI, Exabyte does
not support single-ended devices on the autoloader’s LVD SCSI bus.
✔
Narrow SCSI and wide SCSI.
Because the autoloader is a wide SCSI device,
all other devices on the bus must be wide.
✔
SCSI cable lengths
. Make sure the SCSI cabling does not exceed maximum
lengths (see
).
✔
Termination
. Make sure your bus is properly terminated as described on
. Make sure that you use the correct terminator (see
). If
another SCSI device previously terminated the SCSI bus and is no longer at
the physical end of the bus, be sure to remove the terminator from that
device.
✔
Compatibility.
Make sure that your autoloader and tape drive are
compatible with the application software you plan to use. Contact Exabyte
Technical Support or your sales representative for the latest compatibility
information.
