NETWORK VP ISSUE: single station not turning on or stuck on

To power down a Network VP system, flip the circuit breaker on the power supply inside the cabinet to the "Off" position.


The first step to resolving this issue is checking the output board:

  • Check the LED indicator lights on the output board. If one is stuck on, then the output board must be sent in for reconditioning. Create a UPS Shipping Label HERE.
  • Check the connector the ribbon cable plugs into for corrosion on the pins.
  • Verify that there is a good connection, free of corrosion and debris, between the 8-station output board and the switch and surge board.
  • Check the output contacts on the bottom of the board for debris and corrosion.
  • The problem may be related to the faceplate or ribbon cable. Check this by swapping the output board with a known operational output board.
 

If the output board is functional, test the distribution board:

  • Check that there is a green indicator light when the system is powered on, which indicates that the board is receiving proper power from the transformer. If there is no light, verify that there is proper voltage coming out of the transformer by using a multi-meter on the power plug going into the distribution board. There should be approximately 14V AC. If the voltage is not correct, the transformer must be sent in for reconditioning. Create a UPS Shipping Label HERE.
