Chapter 1: Setting upStheettiDngiskUpDrthivee Jukebox Table 1-1 NOTE Setting Up the Jukebox Connecting the SCSI Cables to the Jukebox Connecting the SCSI Cables to the Jukebox In all configurations, the following cabling capabilities apply: Interface types available Number of interface cards available Number of hosts Single-ended or differential SCSI, selected by the interface selection switch on each interface card One card in 4- and 6-drive models, two cards in 10-drive models This jukebox may be used in high availability environments. High availability environments can be complex and are not described in this guide. Consult with your high-availability vendor for installation and configuration. 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. Maximum SCSI External Cable Lengths (Assuming no devices internal to the host computer) Interface Type Maximum External Cable Length Single-Ended SCSI (50-pin high-density connector) Differential SCSI (68-pin high-density connector) 3 meters (9.8 feet) 25 meters (82.0 feet) 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. Chapter 1 1- 7
