All Phones Dead: No Dial Tone or Lights
Possible Cause 1: Control unit is not receiving power.
What to do: Make sure the control unit’s power cord is plugged securely into the wall
outlet. Also make sure the on/off switch is in the “ON” position (“O”) if you have a 5-Slot
carrier.
If the green LEDs on the modules are lit and the trouble is gone, the problem is
corrected.
If the green LEDs on the modules are lit but the trouble remains, call the hotline.*
If the green LEDs on the modules are out, go to Possible Cause 2.
If any green LEDs on the modules are flashing, call the hotline.*
Possible Cause 2: The power outlet is faulty.
What to do: Test the outlet by plugging in an appliance, like a lamp or radio.
If the appliance does not work, the outlet is faulty. If possible, plug the control unit
into a different outlet. Then check the fuse box or call an electrician.
If the appliance works, go to Possible Cause 3.
Possible Cause 3: A control unit fuse is blown.
What to do: Call the hotline.*
Multiple Phones Dead: No Dial Tone or Lights
Possible Cause 1: The LED on one system module is out.
What to do:
If the green LED on the front of a module is out, try reseating the module in
the control unit.
If the LED lights, the problem is corrected.
If the problem remains, call the hotline.*
Possible Cause 2: The green LEDs on several system modules are out.
What to do: If the LEDs on the front of several system modules are out, try reseating the
leftmost module of the ones with the lights out (see “Replacing System Modules” in the
PARTNER Advanced Communications System Installation guide).
If the LEDs light, the problem is corrected.
If the problem remains, call the hotline.*
