4.2 Introduction to indicator lights
MESH LED
1. The red light is on during the boot process, the boot is complete, the red light
is off and the green light is on
2. Press the mesh button to enter the mesh pairing state, the green light flashes
once a second, and the other lights are off
3. The main equipment network is normal, the green light and blue light are on
at the same time (cyan)
The slave device MESH is successfully connected, and the distance is longer, the
green light and the red light are on at the same time (orange), the distance is
suitable for the green light and the blue light is on at the same time (cyan)
WAN LED
When connecting the WAN ports, the LED light will be always on, and
the LED will be flashing when there is data communication
LAN1 LED
When connecting the LAN ports, the LED light will be always on, and
the LED will be flashing when there is data communication
LAN2 LED
When connecting the LAN ports, the LED light will be always on, and
the LED will be flashing when there is data communication
LAN3 LED
When connecting the LAN ports, the LED light will be always on, and
the LED will be flashing when there is data communication
4G/5G LED
When insert SIM card, the LED light will be always on, and the LED
will be flashing when there is data communication
POWR LED
when the power supply is normal, the power indicator is always on, and
it won’t be on when the power supply is abnormal.

4.4 Introduction to hardware watchdog function
This hardware product is designed with a hardware watchdog function. The hardware watchdog
will automatically turn on after power-on, and detect the heartbeat level output by the routing
system that jumps once per second. If the routing system itself fails (such as a crash), it will also
Naturally, the heartbeat level can no longer be output. At this time, if the hardware watchdog does
not detect the heartbeat level within 120 seconds, it will shut down itself for 15 seconds and then
restart the entire system.
When the routing system is operating normally, but the 5G/4G module dialing is abnormal, the
routing system will control the power supply of the 5G/4G module through GPIO and let the
module automatically restart to fix the 5G/4G dialing abnormal problem.
Hardware watchdog specific functions
Routing system is abnormal
Module dialing abnormal
Restart the whole system
Only restart the module
5 5G/4G mobile communication function
This product has a built-in M.2/MiniPCIE interface, which can be used to expand
5G/4G mobile communication functions. The built-in M.2/PCIE interface supports
USB3.0 and USB 2.0 buses. 5G mobile communication supports NSA or SA, and
which frequency bands are specifically supported by the selected 5G module. At
present, this product has completed the joint debugging with Fibocom's FM150 series
modules.
