ROUBLESHOOTING SUGGESTIONS
Steady GREEN
There is normal communication
between the adaptor card
PC710A and the computer.
In this case, the state of the LED on the computer
motherboard (internal) has no special significance.
Blinking GREEN
There is no communication
between PC710A and the
computer.
The LED on the computer motherboard (internal) indicates
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.
Blinking RED
The computer is in the process
of restarting, following
programmatic activation of the
of the power button (PW_BN).
Same as for “Blinking GREEN” above.
Steady RED
Activation of the power button
(PW_BN) failed to invoke an
orderly shutdown of the
computer, so a reset of the
computer has been effected via
the computer’s reset button
(RST_SW).
Same as for “Blinking GREEN” above, plus the following:
•
The wiring between PC710A and the power button
(PW_BN) may be faulty, leaving PC710A no
choice but to use the reset button (RST_SW).
OFF
There is no communication
between PC710A and the
computer, and the LED on the
computer motherboard
(internal) is OFF.
There may be a problem with the input power for the
computer motherboard – either the power itself or the cable.
