With 45k impedance, If 3 PSE's were connected together -
(with misconfigured wiring, one at each end, and one midspan - ?)
would it not be possible for one PSE to see the sense
impedance of the other two PSE's as the correct detection
resistance? That is, 45k/2 = 22.5k - in some situations,
for instance the other two PSE's being powered off, will
the third PSE not then try and erroneously power the circuit?
