Ok, I just unplugged my power connector to a card with 4 FXO modules and
they no longer work. 

Plug it back in and it works.....

BS! Fxo modules do "not" require the power connector, period. The
connector
is only used to develop ringing voltage for fxs modules. It's very easy
to
trace the power connector wiring and find that it goes nowhere when fxo
modules
are used.
