How to Troubleshoot a 2N Device That Won't Reset
Performing a factory reset on a 2N IP intercom or access control unit is a critical troubleshooting step for resolving network issues, clearing a forgotten password, or restoring the device to its original state. However, the process can sometimes be tricky, and if not done correctly, it will fail, leaving the device with its old configuration.
If you've been trying to reset your 2N device without success, this guide will provide you with a clearer understanding of the procedure, the meaning of the LED signals, and what to do when it doesn't go as planned.
## Common Symptoms of a Failed Reset
You'll know the reset has failed if you observe the following:
- The device boots up normally instead of entering the reset or static IP address mode.
- The default login credentials do not work after the supposed reset.
- The device retains its previous IP address instead of reverting to the default static IP (192.168.1.100) or DHCP mode.
- The LED indicators do not flash in the specific sequence described in the manual during the reset attempt.
- The reset button feels unresponsive or does not have a tactile click.
## The Correct 2N Factory Reset Procedure
The single most common reason for failure is not following the sequence with the correct timing. Unlike many devices where you just hold a button, the 2N reset is interactive and requires you to observe the device's status LEDs.
Note: The exact LED colours can vary slightly between models (e.g., Verso, Solo, Force). Always consult your specific model's installation manual if possible.
### The General 'Power Cycle' Reset Method
-
Disconnect Power: Completely disconnect the 2N device from its power source. This means unplugging the Ethernet cable if you are using Power over Ethernet (PoE) or disconnecting the 12V external power supply.
-
Press and Hold the Reset Button: Locate the reset button. On some models, it's a physical button; on others, it's two contact pads labelled 'RESET' that you need to bridge with a screwdriver or tweezers. Press and hold this button/short the pads.
-
Reconnect Power: While you are still holding the button, reconnect the power supply to the device.
-
WAIT and WATCH the LEDs: This is the most critical step. Do not release the button yet. The device will start to boot, and the status LEDs will cycle through various colours and patterns. This can take 15-30 seconds.
-
Release at the Right Time: You must release the reset button only when the LEDs indicate the correct state. Typically, the device will first enter an 'update' mode (e.g., green/orange flashing) and then a 'reset' mode. For a factory reset, you often need to wait until the status LED turns a solid orange or red. Releasing the button during the wrong state will abort the reset.
-
Confirmation: After you release the button at the correct time, the device's LEDs will change again to confirm the reset is in progress. The device will then reboot with its factory default settings.
### Troubleshooting Common Failure Points
-
Problem: The LEDs never change to the reset state.
- Solution: You may be releasing the button too early. Make sure you are holding it continuously from before power is applied until you see the correct LED signal. This can take up to 30 seconds or more.
-
Problem: The device just boots up normally.
- Solution: This indicates the reset button press was not registered. Ensure you are pressing the button firmly and feel a click. If using reset pads, make sure your tool is making a solid connection between them. Also, verify your power source (PoE switch or adapter) is functioning correctly.
-
Problem: I've reset it, but I can't access it.
- Solution: After a successful reset, the 2N device will have its network settings wiped. It will likely revert to a default static IP address (e.g., 192.168.1.100). You will need to change your computer's IP address to be on the same subnet (e.g., 192.168.1.99) to be able to access the web interface and reconfigure it.
Patience is key. The 2N reset process is precise, so carefully observing the device's feedback via its LEDs is essential for success.
