Section 2: Basic Installation12 AXIS 850/950 User’s ManualSCSI Devices and TerminationCD-ROM server termination set-upThe SCSI bus allows seven CD-ROM drives to be connected to theCD-ROM server. Each unit on the SCSI bus must have an uniqueSCSI address. SCSI addresses 0 through 6 can be used for the CD-ROM drives connected to the CD-ROM server.Termination In order for the SCSI bus to work properly, it has to be electricallyterminated at both ends. This is usually done by attaching aterminator plug to the last unit in the SCSI chain. Modern SCSIdrives may have built-in termination, which is activated or deactivatedusing a switch on the back panel. Check the documentation for yourCD-ROM drive to see how to terminate the drive properly.Drive terminated,Axis CD-ROM servertermination on.AXIS 851 or AXIS 951 with internal drive onlyDrive terminated,Axis CD-ROM servertermination off.Not terminated Not terminated Last drive terminatedAXIS 851 or AXIS 951 with external CD-ROM drives connectedAxis CD-ROM servertermination on.Not terminated Not terminated Last drive terminatedAXIS 850 or AXIS 950 with one or more external CD-ROM drives
