Problems encountered during the installation of the ValueLoader
are usually caused by improper SCSI bus configuration,
application software configuration errors, or an incorrectly
configured operating system. If the application software that you
are using is not communicating with the ValueLoader after
installation, check the following:
•
SCSI ID: The ValueLoader uses two SCSI IDs: one for the tape
drive and one for the ValueLoader robotics. Depending on the
SCSI IDs of the other devices on the same SCSI bus, you may
need to change one or both of these SCSI IDs before you can
use the ValueLoader. Select an unused SCSI ID. See the
manuals for the other devices on the SCSI bus or your
operating system to determine which SCSI IDs are currently in
use. If the ValueLoader is attached to a narrow (50-pin) SCSI
bus, only SCSI IDs 0 through 7 are available. See Changing the
SCSI ID on page 36.
•
SCSI Cabling: Verify that all SCSI cables are securely connected
at both ends. Check the length and integrity of your SCSI
cabling. The total length of all cables must not exceed the
following lengths:
• SCSI-1 SE bus: 6 meters (19 feet)
• Fast or Ultra SCSI (Narrow or Wide) SE bus: 3 meters
(10 feet)
• LVD bus with multiple devices: 12 meters (40 feet)
• LVD bus with a single device: 25 meters (82 feet)
The length of the SCSI cabling inside the ValueLoader is 60 cm
(2 feet). This length must be included in any calculations of
total cable length. Replace suspect SCSI cables with known
good cables.
