Also check the cables for proper ends.  Just had a customer this week where the
maintenance guy was peeling back the shield to get the ends on easier! 
Interestingly this allowed your choice of ONE terminal to work.  Turn on more
than that and they all died.

If you can't find a twinax testor, turn off all the devices, and disconnect the
twinax at the AS/400 end.  WIth a DMM or Ohm meter measure from each pin to the
shield and you should get approx 55 Ohms.  Also measure from pin to pin and you
should get approx 110 Ohms.
