Yellow LED
The purpose of the yellow LED is to indicate that a connection to the communication network, either via satellite or cellular connection, is being attempted. This does not indicate that there is an appropriate signal to make a satellite or cellular connection, only that the hardware is working properly, and is capable of making a connection given that a signal is present.Yellow LED OFF - The yellow LED should be OFF when an external antenna is not present or when an external antenna has been connected backwards. If the green LED is ON, and the yellow LED is OFF, refer to System Operation Testing and Adjusting, UENR5823, "Cellular Radio Does Not Communicate".Yellow LED Blinking - The yellow LED will blink when the cellular radio, or satellite radio is trying to make a connection. If a cellular radio continues to blink for longer than five minutes, and is in an area known to have a good cellular signal, check the installation of the external antenna if equipped. If that does not resolve the situation, refer to System Operation Testing and Adjusting, UENR5823, "Cellular Radio Does Not Communicate".Yellow LED ON - The yellow LED will be ON when a good connection through either cellular or satellite communication is detected, depending on the radio type.Blue LED
The purpose of the blue LED is to determine when Ethernet or CAN datalinks are present. In the case of the "Elite" system, the radio will be detecting if it can see a Network Manager on the Ethernet connection. In the case of the "Pro" system, the radio will be detecting if it can see any traffic on the CAN Datalink.Blue LED OFF - The blue LED will be OFF when no information is present on the data link. For the "Elite" system, check the Ethernet wiring from the Network Manager. For the "Pro" system, check the CAN wiring that is connected to the equipment being monitored.Blue LED ON - The blue LED will turn ON when the radio is receiving data, and will turn OFF when it is not receiving data. This should not be confused with blinking. If the blue LED blinks on a regular, continual basis, and does not appear to be transmitting data properly, contact the Dealer Solutions Network for next steps.Radio Disable Switch (Optional)
The Radio Disable switch is used to disable power to the cellular or satellite radio when transmitting a radio signal is not desired. The A5N2 Network Manager will continue to record data from equipment operations, even though the cellular or satellite radio is powered off.Refer to Table 13 for the components necessary to install a radio disable switch.
