Determining SCSI Bus Length

Fast, Wide Differential SCSI Bus Length

Follow these instructions to calculate your total bus length for the fast, wide differential SCSI bus on your system, using Table 25.

1List all of your internal fast, wide differential SCSI devices in the first column.

2In the third column, write the lengths of the internal fast, wide differential SCSI bus that correspond to your devices.

3In the fourth column, write down the lengths of the fast, wide differential SCSI interconnect cables you are using for your installation. (Cable lengths are listed in subsection “Cables” in the section on “SCSI Restrictions.”)

4Add all of the numbers in the third column and write the sum on the subtotal line at the bottom of the column. Do the same for the fourth column.

5Add the subtotals together and write the total on the Total Fast, Wide Differential SCSI Bus Length line.

NOTICE:The total length of thefast, wide differentila SCSI bus must not exceed 25 meters (82 feet). If the number you write for Total Fast, Wide Differential SCSI Bus Length is greater than 25 meters, try conﬁguring your installation with shorter cables.
