Section 1: General Information
6.1
Cabling Limitations
Maximum total allowable cable length for a differential SCSI interface is 82 feet (25 meters). This distance
must be measured from the controller to the last device on the bus. Cables must be 110 ohm twisted pair. If
you are using a cable of unknown composition, replace it with the one provided by HP. When ordering,
reference one of these part numbers:
519-001W
519-003W
519-015W
519-020W
519-023W
6.2
Differential Devices
The 5242 and 5242-ACL tape drives support a high voltage differential SCSI-3 interface.
6.3
Cooling Fan and System
The cooling system provides excellent heat dissipation at critical locations, such as read/write heads, where
excess heat results in higher data failure. A unique airflow design directs cool air over these critical locations
within the chassis.
