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, 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.*
