This is all consistent with a non-listening NIC and a unit in 
profound hibernation, if not affirmative shutdown [NIC lights 
will be powered on and blink by stray ARP broadcast packets 
moving across a lan, even on switched fabric]

  would set up remote syslogging from the unit under test, and 
see exercise (through keyed ssh access) that unit under test 
on a scripted basis, to see if it dies off if left alone, or 
if other clues appear in that remote syslog
