The meaning of these lights changes depending on whether the UBox is booting up (you have just turned on the UBox), or if it is running.
The two tables on the following pages show all of the possible states of these LED lights and what they mean. If you are having problems with your UBox, please use this information in conjunction with the information in 7: Troubleshooting to diagnose the problem.
Note: SYSTEM lights 2 and 3 on the UBox 4100 are red; they are amber on the UBox 2100.
