StorageLoader Installation and User Manual
If a problem occurs during the power-on sequence, the
StorageLoader will display an error message on the display. Refer
to chapter 4.2 and 7, to learn the procedures for resolving the
problem.
Step 6. Setting the SCSI Address
The SCSI address is a unique address that identifies the unit
connected to the SCSI bus. The StorageLoader uses two SCSI
addresses or I d’s. One is for the loader robotics controller and the
other is for the tape drive. The SCSI addresses can be configured
through the operator buttons and th
e display on the front panel. In
most cases the default addresses can be used. The default SCSI
address for the StorageLoader robotics is 4 and the tape drive has
SCSI address set to 5.
To set the SCSI addresses for the StorageLoader and the built in
tape
drive, refer to section
4.4.2

for more
inform ation. You m ay also wish to reserve a magazine slot for a
cleaning cartridge, and set a security password at this time. Once
som e settings are changed, the StorageLoader and the drive may,
if required, automatically reboot.
Step 7. Connecting the SCSI Bus Cable
Guidelines before connecting the SCSI cable:
A)
Before the SCSI bus cable is connected to the
StorageLoader, turn the StorageLoader
main
power switch
off.
B)
Make sure that your host system is in a state were a new
SCSI device can be safely connected to the SCSI bus.
C)
Do not exceed SCSI bus length restrictions.
1.
Add the length of all external and internal SCSI cables
on the
bus
2.
Add 80 cm (31.5 inch) for the internal cable length in the
StorageLoader.
3.
The maximum allowed length of an LVD SCSI bus is 12 m
(39 ft) if the number of SCSI devices exceeds two.
4.
For an SE SCSI bus, be very careful regarding bus length.
The norm al com bination has a SE bus transfer speed of 160
Mbyte/s with a maximum bus length of 3 m (9.8ft) and up to
4 SCSI devices connected. If your SE system operates with a
different transfer speed or
has
more than 4 SCSI devices, we
refer to the actual SCSI standard for complete bus length
restrictions.
