Input Power LED is extinguished
The Input Power LED is illuminated when the mpx100/100b logic circuitry is receiving proper voltages. If
the Input Power LED is not illuminated:
1.
Inspect power cord and connectors. Is the cord unplugged? Is the cord or connector damaged?
• If yes, make necessary corrections or repairs. If the condition remains, continue with the
next step.
• If not, continue with the next step.
2.
Inspect AC power source. Is the power source delivering the proper voltage?
• If yes, continue with the next step.
• If not, make the necessary repairs. If the condition remains, continue with the next step.
3.
Replace the mpx100/100b.
System Alert LED is illuminated
