NOTICE NOTICE SCSI Connections Determining SCSI Bus Length Determining SCSI Bus Length This section helps you to determine the total length of the NSE SCSI bus and the FWD SCSI bus and the Ultra, wide-SE bus. NSE SCSI Bus Length Follow these instructions to calculate your total NSE SCSI bus length (including the system unit, external NSE SCSI devices, and NSE SCSI interconnect cables) using Table 22: 1 Find all of your external NSE SCSI devices in the first column. In the third column, write the NSE SCSI bus lengths (from the second column) that correspond to your devices. In the third column, the length for the System Unit is already listed. This number must always be used for the system unit. 2 In the fourth column, write down the lengths of the NSE SCSI interconnect cables you are using for your installation. (Cable lengths are listed in subsection "Cables" in the section on "SCSI Restrictions." 3 Add all of the numbers in the third column and write that number on the subtotal line at the bottom of the column. Do the same for the fourth column. 4 Add the subtotals together and write the total in the Total NSE SCSI Bus Length box. The total length of the NSE SCSI bus must not exceed 6 meters (19.6 feet). If the number you write for Total NSE SCSI Bus Length is greater than 6 meters (19.6 feet), try configuring your installation with shorter cables. If you have problems, call your designated service representative. 180
