1 NEXT PREVIOUS JUMP CONTENTS INDEX SETTING UP THE JUKEBOX CONNECTING THE SCSI CABLE TO THE JUKEBOX The jukebox can be connected to either a single-ended or low-voltage differential SCSI bus. The connectors are highdensity 68-pin. When connecting to a single-ended SCSI bus, and because the drives are "fast SCSI" you have a maximum of 9.8 feet (3 metres) for the entire bus. The jukebox uses 16 inches (0.4 metre) internally so 8.5 feet (2.6 metres) remain available for your use. This assumes that you do not have internal devices (disks, etc. connected to the bus. If you do, the maximum allowable external bus is reduced by the amount of internal bus used. When connecting to a low-voltage differential SCSI bus, you have a maximum of 39.4 feet (12 metres) for the entire bus. As mentioned above, the jukebox uses 16 inches (0.4 metre) internally so 38 feet (11.6 metres) remain available for your use. This assumes that you do not have internal devices (disks, etc. connected to the bus. If you do, the maximum allowable external bus is reduced by the amount of internal bus used. This jukebox can be connected to your host computer in two ways: • as the only SCSI peripheral on a bus • as one of multiple SCSI peripherals on a bus 10

The jukebox can be connected to either a single-ended or low-voltage differential SCSI bus. The connectors are high-
density 68-pin.
When connecting to a single-ended SCSI bus, and because the drives are “fast SCSI” you have a maximum of 9.8 feet
(3 metres) for the entire bus. The jukebox uses 16 inches (0.4 metre) internally so 8.5 feet (2.6 metres) remain available
for your use. This assumes that you do not have internal devices (disks, etc. connected to the bus. If you do, the maxi-
mum allowable external bus is reduced by the amount of internal bus used.
When connecting to a low-voltage differential SCSI bus, you have a maximum of 39.4 feet (12 metres) for the entire
bus. As mentioned above, the jukebox uses 16 inches (0.4 metre) internally so 38 feet (11.6 metres) remain available for
your use. This assumes that you do not have internal devices (disks, etc. connected to the bus. If you do, the maximum
allowable external bus is reduced by the amount of internal bus used.
This jukebox can be connected to your host computer in two ways:
•
as the only SCSI peripheral on a bus
•
as one of multiple SCSI peripherals on a bus
