NIASAT provides 99.9% uptime for SCADA and Oil and Gas. NIASAT systems are easy to troubleshoot, even remotely, but only if you know the colors of the LEDs. If you are troubleshooting with NIA and if your do not see orange/amber and yellow/green, please tell us and we will help you identify the LED states. Our satellite modems only have one functional state – solid green RX, solid green TX, solid green NET and Solid Green PWR. The following account is an anecdote from one of our technicians.
Upon receiving a call from a customer about their service being down, to my surprise they were telling me that the RX light was green, (verifies receive lock from the satellite to your dish) as was the TX. Which would imply the modem is acquiring into the network – alas allowing internet browsing. : )
To my dismay the modem would not acquire into the network. After verifying again that the customer did have a solid green RX light I transmitted a carrier to verify connectivity and to my dismay I was not able to see any transmission. Which would imply:
- Bad cable or cable end
- Bad BUC
- No power coming from the TX port of the modem
- They aren’t “on” the Satellite.
However, the customer was saying that yes, they had a green RX light. So I continued trouble shooting … I had them roll the cables (switching TX and RX cables at dish and the modem) to verify that that cable going from the modem to the buc was indeed a good cable. After rolling the cabl, I was informed that yes the customer did again have a solid green RX and TX but it would not acquire into the network.
After more trouble shooting ALL was revealed! The customer after much deliberation, and somewhat reluctantly, told me they are a “little” color blind. So when he was telling me green lights across the modem they were actually amber!
LED Lesson # 1 make sure the end user isn’t color blind when verifying the colors of the modem LEDs!
