Are you connecting them to the same SCSI channel? If so, I trust you
are attaching them like so:
Adapter+------+Backplane 1+--+Backplane 2+-Terminator
You can't hook them up like this:
Adapter+------+Backplane 1+-Terminator
|
+--+Backplane 2+-Terminator
|
+-Terminator
Even in configurartion 1, there are lots of backplanes out there
that fair much worse than a good U320 cable. You may find that
your backplanes just are not good enough to run U320.
