This chapter provides explanations for LED actions on a RUT955 router. The information applies for
both Quectel and MeigLink modules used in Teltonika devices.
Contents
1 Power LED
2 Ethernet port LEDs
3 Connection status LED
4 Signal strength LEDs
Power LED
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
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.

Connection status LED
The connection status LED is located on the bottom right corner of the front panel, between the
input/output connector and 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
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, 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. When all 5 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.
