CTIVE
There is normal communication
Steady GREEN between the adaptor card
PC710A and the computer.
There is no communication
Blinking GREEN between PC710A and the
computer.
The computer is in the process
of restarting, following
Blinking RED
programmatic activation of the
of the power button (PW_BN).
Activation of the power button
(PW_BN) failed to invoke an
orderly shutdown of the
Steady RED computer, so a reset of the
computer has been effected via
the computer's reset button
(RST_SW).
There is no communication
between PC710A and the
OFF computer, and the LED on the
computer motherboard
(internal) is OFF.

that the computer is operating. One of the following
conditions may be interfering with communication:
•
The computer may be starting up.
•
The computer may have hung (frozen or looping).
•
There may be a problem with the computer's serial
port.
•
There may be a problem with the cable between
PC710A and the computer.
•
Card PC710A may be faulty.
Same as for "Blinking GREEN" above.
Same as for "Blinking GREEN" above, plus the following:
•
The wiring between PC710A and the power button

computer motherboard – either the power itself or the cable.
