Fast, Wide SCSI-3 Bus Length

Follow these instructions to calculate your total fast, wide SCSI-3 bus
length for the fast, wide SCSI-3 bus on your system using Table C–6:
1.
List all of your internal SCSI-3 devices in the first column.
2.
In the second column, write the lengths of the internal SCSI-3
bus that correspond to your devices.
3.
In the third column, write down the lengths of the SCSI-3 inter-
connect cables you are using for your installation. (Cable lengths
are listed in subsection "Cables" in the "SCSI Restrictions" sec-
tion.)
4.
Add up all of the numbers in the second column and write that
number on the subtotal line at the bottom of the column. Do the
same for the third column.
5.
Add the subtotals together and write the total in the Total SCSI-3
Bus Length box.
NOTICE: The total length of the SCSI-3 bus must not ex-
ceed 25 meters (82 feet). If the number you
write for Total SCSI-2 Bus Length is greater
than 25 meters (82 feet), try configuring your
installation with shorter cables.
If you have problems, call your designated service representative.
