This chapter provides explanations for LED actions on a RUT240 router.
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:
|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:
|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 LEDs
The connection status LEDs are located on the left side of the front panel, between the power connector and the signal strength indication LEDs:
The LED displays the router's current connection state and network type among a few other things:
|2G and 3G LEDs blinking every 1 second||No SIM or bad PIN|
|Blinking from 2G LED to 3G LED repeatedly||SIM holder is not inserted or access to network is denied|
|2G/3G LED blinking every 1 sec||Connected to 2G/3G, no data session established|
|2G/3G LED turned on||Connected to 2G/3G with data session|
|2G/3G LED blinking rapidly||Connected to 2G/3G with data session and data is being transferred|
Signal strength LEDs
The signal strength LEDs are located in the center of the front panel, to the right of the connection status LEDs:
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.
After the router gets powered up, all signal strength LEDs will turn ON and stay ON for about 40 seconds or until the router's modem registers on a network - after this, the LEDs will start displaying the router's current signal strength.
