Connecting the SCSI Cables to the Jukebox
The following is general cabling information.
The maximum cable length you have available for connection to your host computer
system or other devices depends on which interface type you select. The following
table lists the maximum SCSI bus lengths available to you.
Table 1-1 Maximum SCSI External Cable Lengths (Assuming no devices internal to the
host computer)
NOTE Hewlett-Packard recommends that you use SCSI cables with thumbscrew
connectors. Clip type cables may be used if you first remove the mounted
thumbscrew studs with a flat blade screwdriver. If the thumbscrew studs are not
removed, interference between the cable and the studs may result.
Interface types available Single-ended or differential SCSI, selected by
the interface selection switch on the top of the
interface module (see “6” on Figure 1-2).
