RUTM31 LEDs
This page contains information the different types of LEDs and their behaviour on a RUTM31 device.
Power LED
The power LED is located on the bottom left corner of the front panel, just under the power connector.
It indicates whether the device is powered on or not.
| State | Description |
|---|---|
| LED turned on | Device is powered on. |
| LED turned off | Device is not powered on. |
WiFi band LEDs
The WiFi band LEDs are located at the bottom of the front panel of the device, to the left of the Ethernet ports.

They display whether a WiFi Access Point (AP) is active on a specific band.
| State | Description |
|---|---|
| 2.4 LED turned on. | At least one 2.4 GHz Access Point is running. |
| 2.4 LED turned off | No 2.4 GHz Access Points are running. |
| 5 LED turned on | At least one 5 GHz Access Point is running. |
| 5 LED turned off | No 5 GHz Access Points are running. |
WAN type LEDs
The WAN type LEDs are located at the top-right of the front panel.

They indicate which type of Internet connection is currently active.
| State | Description |
|---|---|
| SIM1 LED on | A mobile data connection on SIM1 is active. |
| SIM1 LED off | A mobile data connection on SIM1 is inactive. |
| SIM2 LED on | A mobile data connection on SIM2 is active. |
| SIM2 LED off | A mobile data connection on SIM2 is inactive. |
| WiFi LED on | A WiFi data connection (WiFi WAN) is active. |
| WiFi LED off | A WiFi data connection (WiFi WAN) is inactive. |
| ETH LED on | An Ethernet data connection (wired WAN) is active. |
| ETH LED off | An Ethernet data connection (wired WAN) is inactive. |
Ethernet port LEDs
There are two LEDs located at the top of each Ethernet port.
They provide information on the current states of the Ethernet ports. Each port has two LEDs:
- Orange - 10/100 Mbps connection
- Green - 1000 Mbps connection
Below is an explanation on the behaviours of green and orange LEDs.
| State | Description |
|---|---|
| LED on | A data connection on the port is operational (cable plugged in, end device visible, no data is being transferred). |
| LED off | No data connection on the port is operational (no cable, bad cable or end device not visible for some other reason (such as damaged network card). |
| LED blinking | Connection established and data is being transferred over this port. |
Mobile network type LEDs
The mobile network type LED is located on left side of the front panel:
Indicates that the device has an Internet connection.
| Action | Description |
|---|---|
| Yellow lit and blinking on data | Device is connected to a 3G. |
| Yellow blinks every 1s | Establishing data connection 3G. |
| Green lit and blinking on data | Device is connected to a 4G. |
| Green blinks every 1s | Establishing data connection 4G. |
| Blue lit and blinking on data | Device is connected to a 5G. |
| Blue blinks every 1s | Establishing data connection 5G. |
| Blinking: red -> green -> blue | No SIM inserted. |
| Blinking: yellow -> green -> blue | The device is attempting to connect to a mobile network operator. |
Mobile signal strength indication LEDs
The mobile signal strength indication LED is located on left side of the front panel.
The color of lit up LED represents a different mobile signal strength (RSSI) value in dBm.
| Color of lit up LED | Signal strength value |
|---|---|
| Red blinking | ≤-110 dBm |
| Red lit | -110 dBm to -82 dBm |
| Yellow lit | -81 dBm to -52 dBm |
| Green lit | ≥ -51 dBm |
The Mobile signal strength LED and Mobile network type LED behavior in bootloader and recovery modes:
| Mode | Behavior |
|---|---|
| Bootloader | |
| Recovery | |
| Booting device | |
| Flashing FW |
