Introduction to Indicator Functions
| S1 LED | Data communication indicator between 5G module and routing SOC |
| LAN1 LED | The Internet port is always on and flashes when there is data communication |
| LAN2 LED | The Internet port is always on and flashes when there is data communication |
| LAN3 LED | The Internet port is always on and flashes when there is data communication |
| WAN LED | The Internet port is always on and flashes when there is data communication |
| Power LED | It is always on when the power supply is connected, but not on when the power supply is faulty or not connected |
| 2.4G WIFI LED | It is always on when the 2.4G WIFI function is turned on, flashes when there is data communication, and does not light when the 2.4G WIFI function is not turned on or when the 2.4G WIFI function is faulty |
| 5.8G WIFI LED | It is always on when the 5.8G WIFI function is turned on, flashes when there is data communication, and does not light when the 5.8G WIFI function is not turned on or when the 5.8G WIFI function is faulty |
| 5G LED | It is always on when the routing system identifies and successfully attaches the 5G mobile communication module, and it is not on when the 5G mobile communication module fails or is not connected to the 5G mobile communication module |
| Internet LED | The device dials successfully through the 5G mobile communication module or WAN port. It is always on when communicating with the Internet normally, but not when the device cannot access the Internet |

Introduction to watchdog function
When the routing system operates normally, but only the 4G/5G module dials abnormally, the routing system can control the power supply of the 4G/5G module through GPIO to automatically restart the 4G/5G module to repair the dialing exception.
When the system operates abnormally, the hardware watchdog function will restart the whole system.
5G module interface description
This product has a built-in 5G module. After the 5G module dials up to the Internet, it is converted into a 1000M network interface through the RGMII bus of the 5G module, and then connected to the routing SOC network interface to share the 5G network. In this way, the high-speed 5G network can be shared to the routing SOC to the maximum extent, and will not be limited by the USB3.0 data bus of the routing SOC, so that the 5G high-speed network cannot be fully used.
