Determining SCSI Bus Length
at the bottom of the column. Do the same for the fourth column.
5 Add the subtotals together and write the total on the Total FWD SCSI Bus Length
line.
NOTICE: The total length of the FWD SCSI bus must not exceed 25 meters (82 feet).
If the number you write for Total FWD SCSI Bus Length is greater than 25
meters, try configuring your installation with shorter cables.
If you have problems, call your designated service representative.
Subtotals: ______________ + ________
Total FWD SCSI Bus Length = ______________

Ultra, Wide-SE SCSI Bus Length
Follow these instructions to calculate your total bus length for the UW-SE SCSI bus
on your system, using Table 23.
1 List all of your internal UW-SE SCSI disk drives in the first column.
2 In the third column, write the lengths of the internal UW-SE SCSI bus that corre-
spond to your devices.
3 In the fourth column, write down the lengths of the UW-SE SCSI interconnect
cables you are using for your installation. (Cable lengths are listed in subsection
“Cables” in the section on “SCSI Restrictions.”)
