MicroSIM cards slots

Fig. 4.4: MicroSIM cards slots

The M!DGE router is equipped with two MicroSIM (3FF) cards slots which are placed under a SIM card cover. Use PH0 screw driver for its opening. If using only one SIM card, use holder one.

The SIM card holder has a locking mechanism – for opening pull the front part of the holder down and then you can open it. After inserting of SIM card (cropped edge left, connectors down), close the holder and lock it.


Power off the router before inserting the SIM card.

Polarity Reversal protection circuit (PTC fuse) used on pin 1 and pin 2, but the reverse polarity with soft power supply could cause damage after a few minutes of wrong polarity attached.

Pins 2 and 3 Pins are internally connected.

RS232: behaves as a DTE device.
Pin 5 voltage -5.4 V (without a connected device ) from HW version 1.5. In earlier HW versions was 0 V.

Pins 6 and 7 are galvanically isolated (1.5 kVAC). If voltage between the + and – pins is bigger than 60 VDC, the input circuit could be damaged. Reversed polarity will not harm the circuit.

4.2.6. Reset button

Reset button

Fig. 4.6: Reset button

The Reset button is placed close to the USB connector. Use a blunt tool no more than 1 mm in diameter (e.g. a paper clip) to press the button.

The reset button has two functions:

  • Reboot the system

    • Press at least 3 seconds to release a system reboot.

    • The reboot is indicated with the red blinking STAT LED.

  • Factory reset

    • Press at least 10 seconds to release a factory reset.

    • The start of the factory reset is confirmed by all LEDs lighting up GREEN for a second.

  • Recovery procedure

    • Press at least 15 seconds to release a recovery procedure.

    • The start of the recovery procedure is confirmed by all LEDs lighting up RED for a second.


Contact our technical support ( for recovery procedure details and required files.

EXTon / off / blinkingEXT LED indicates the state of the extension interfaces.
Hint: Cellular (WWAN) signal strength can be indicated (green = excellent, orange = medium, red = weak).

Shows the overall system state. This could be derived from health indicators such as:
– all services up and running
– overall throughput is normal
– CPU load is normal
– the supervisor
– User application (state set by user in SDK or LXC)
