RUT951 LEDs
This page contains information the different types of LEDs and their behaviour on a RUT951 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. |
Ethernet port LEDs
The Ethernet port LEDs are located on the device's front panel, under each respective Ethernet port.
| State | Description |
|---|---|
| LED on | Operating as a 10/100 Mbps connection. |
| LED off | No link established. |
| LED blinking | Connection established and there is activity on this port (data being transferred). |
Mobile network type LEDs
The mobile network type LED is located on the bottom right corner of the front panel, near signal strength indication LEDs.
The LED displays the router's current connection state and network type among a few other things.
| Action | Description |
|---|---|
| Green and red blinking alternatively ever 500 ms | No SIM or bad PIN. |
| Green, red and orange blinking alternatively every 500 ms | Connecting to GSM. |
| Red blinking every 1 sec | Connected 2G, no data session established. |
| Orange blinking every 1 sec | Connected 3G, no data session established. |
| Green blinking every 1 sec | Connected 4G, no data session established. |
| Red lit and blinking rapidly while data is being transferred | Connected 2G with data session. |
| Orange lit and blinking rapidly while data is being transferred | Connected 3G with data session. |
| Green lit and blinking rapidly while data is being transferred | Connected 4G with data session. |
Mobile signal strength indication LEDs
The mobile signal strength indication LEDs are located on the bottom right corner of the front panel, to the right of the connection status LED.
The number of lit up LEDs represents a different mobile signal strength (RSSI) value in dBm.
| No. of lit up LEDS | Signal strength |
|---|---|
| 0 | ≤ -111 dBm |
| 1 | -110 dBm to -97 dBm |
| 2 | -96 dBm to -82 dBm |
| 3 | -81 dBm -67 dBm |
| 4 | -66 dBm to -52 dBm |
| 5 | ≥ -51 dBm |
The Mobile signal strength LEDs can also be used as a time indicator for holding the reset button. When you press and hold the reset button, if there is a User's default configuration configured on the device, you have to hold it pressed for 6 seconds (by default) to initiate a User's default configuration reset and 12 seconds (by default) to initiate a Factory reset. Otherwise, it is only necessary to hold the reset button for 6 seconds to trigger a Factory reset. If the button was held down longer than 20 seconds (by default) no action will be taken.
While holding the reset button each lit up signal strength LED indicate that a period of two seconds has passed. In case with RUT951, when all 5 Mobile signal strength LEDs are lit up, they represent that 10 (LED number multiplied by 2) seconds have passed since you pressed down on the reset button.
After releasing the button at one of the reset periods, all 5 LEDs will start blinking every 1 second. This signifies that the router has begun the reset.
