Power LED off and one or more LEDs flashing
If after power-up or a reset the Power LED is off and one or more of the other LEDs is flashing,
the modem could have a fatal error and may have to be replaced. If
all LEDs are flashing, go to
All LEDs flashing on page 96.
Note: If the Power LED is flashing but no other LED is flashing, this does not indicate a
problem.
1.
If the Power LED is off and one or more of the other LEDs is flashing, try power cycling
the modem:
a) Unplug the power cord from the power source.
b)
If the modem is connected to a DC power source, unplug the DC input cable from the
satellite modem’s power supply.
c) Wait 10 sec.
d) Plug the power cord back into the power source.
e)
If the power source is DC, plug the input cable back into the power supply.
To remove power from the satellite modem, always
unplug the AC power cord from the power source (power outlet, power strip, or surge
protector). Do
not remove the DC power cord from the modem’s rear panel. Doing so could
result in an electrical shock or damage to the modem.
The modem may recover.
2. If the fatal error indication continues, the modem must be replaced. Contact Installer Support.
