RUT951 LEDs
This chapter provides explanations for LED actions on a RUT951 router. The information applies for both Quectel and MeigLink modules used in Teltonika devices.
Power LED[edit | edit source]
The power LED is located on the bottom left corner of the front panel, just under the power connector:
It can perform two different actions:
| ACTION | DESCRIPTION |
|---|---|
| LED turned ON | Router is powered up |
| LED turned OFF | Router is not powered up |
Ethernet port LEDs[edit | edit source]
The Ethernet port LEDs are located on the router's front panel, under each respective Ethernet port:
They represent activity happening on the router's Ethernet ports:
| ACTION | DESCRIPTION |
|---|---|
| LED turned ON | Operating as a 10/100 Mbps connection |
| LED turned OFF | No link established |
| LED blinking | Connection established and there is activity on this port (data being transferred) |
| LEDs light up and turn OFF in sequence from WAN port to LAN1 port | The router is in the bootloader menu state* |
* The bootloader menu is a special router state from which certain upgrades can be performed. For more information on the bootloader menu, click here
Connection status LED[edit source]
The connection status LED is located on the bottom right corner of the front panel, to the left of the 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 |
Signal strength LEDs[edit | edit source]
The signal strength LEDs are located on the bottom right corner of the front panel, to the right of the connection status LED:
Each lit up LED represents a different value of the router's current signal strength in RSSI:
| NO. OF LIT UP LEDs | SIGNAL STRENGTH VALUE |
|---|---|
| 0 | ≤ -111 dBm |
| 1 | -110 dBm to -97 dBm |
| 2 | -96 dBm to -82 dBm |
| 3 | -81 dBm to -67 dBm |
| 4 | -66 dBm to -52 dBm |
| 5 | ≥ -51 dBm |
The signal strength LEDs can also be used as a time indicator for holding the reset button. When you press and hold the reset button, you have to hold it pressed for 5 seconds (by default) to initiate a factory reset. Each second, a new signal strength LED lights up. When all 5 LEDs are lit up, it represents that 5 seconds have passed since you pressed down on the reset button and that you can release it.
After releasing the button, all 5 LEDs will start blinking every 1 second. This signifies that the router has begun the factory reset.
