Troubleshooting
When you lose access to your mrxnode device, the power button lets you recover it without a keyboard, monitor, or network connection. This guide covers each recovery pattern and when to use it.
Power Button Recovery
When you lose access to your device (forgotten password, network misconfiguration, etc.), you can use the power button to recover without needing a keyboard or network connection.
Press Patterns
The power button uses different timeout windows depending on the action:
- 2-second window for quick actions (1-2 presses)
- 10-second window for reset actions (4, 5, 8, 10+ presses)
| Presses | Timeout | Action | When to Use |
|---|---|---|---|
| 1 | 2s | Reboot | Restart the device |
| 2 | 2s | Shutdown | Safely power off the device |
| 3 | - | Nothing | Safety - no action to prevent accidents |
| 4 | 10s | Recovery Mode | Boot into recovery system for troubleshooting |
| 5 | 10s | Boot Latest System | Switch to the latest working system version (A/B) |
| 6 | - | Nothing | Safety - no action to prevent accidents |
| 7 | - | Nothing | Safety - no action to prevent accidents |
| 8 | 10s | Network Reset | Lost network access, wrong WiFi/IP settings |
| 9 | - | Nothing | Safety - no action to prevent accidents |
| 10 | 10s | Factory Reset | Reset device while keeping registration |
How to Perform an Action
- Press the power button the required number of times (e.g., 10 times for factory reset)
- Use short presses - tap and release, don't hold
- Complete all presses within the timeout window (2 seconds for 1-2 presses, 10 seconds for others)
- Wait - the device will perform the action after the timeout window closes
- The device will reboot automatically after most operations
Actions
Reboot (1 press)
Restarts the device. Use this for a quick reboot.
- Press once within 2 seconds
- Device will reboot immediately
- Useful when device needs a simple restart
Shutdown (2 presses)
Safely powers off the device. Use this instead of unplugging when possible.
- Press twice within 2 seconds
- Device will shut down after a brief countdown
- To cancel: wait for the timeout without additional presses
Recovery Mode (4 presses)
Boots the device into recovery mode for advanced troubleshooting.
- Press 4 times within 10 seconds
- Device boots into the recovery system
- Use when the main system won't start properly
- Allows system diagnostics and repairs
Boot Latest System (5 presses)
Switches to the latest working system version (A/B partition switching).
- Press 5 times within 10 seconds
- Device determines the most recent good system version and boots to it
- Use when a system update caused issues
- Helps recover from failed updates
Network Reset (8 presses)
Clears all network settings and restarts. Use when:
- Device has wrong IP address
- WiFi credentials are incorrect
- Cannot connect to the device over the network
After reset:
- Press 8 times within 10 seconds
- Device returns to default network configuration
- You may need to reconfigure WiFi or static IP settings
- Device registration and user data remain intact
Factory Reset (10 presses)
Registration Data Preserved
Unlike previous versions, the factory reset now keeps your device registration. You do not need to contact Mirox support after this reset - the device will remain registered to your organization/user account.
Resets the device to factory defaults while preserving registration. Use when:
- Password is forgotten
- Application is severely malfunctioning
- Need a complete fresh start without re-registering
After reset:
- Press exactly 10 times within 10 seconds
- All user data and settings are erased
- Network settings are cleared
- Device registration is preserved - no support contact needed
- Device can be reconfigured immediately
Important Notes
Short Presses Only
Holding the button for 5+ seconds triggers an immediate hardware shutdown, which cannot be intercepted. Always use quick tap-and-release presses.
Count carefully - The device responds to specific press counts (1, 2, 4, 5, 8, 10). Counts like 3, 6, 7, and 9 do nothing intentionally (safety feature to prevent accidental triggers).
Different timeouts - Quick actions (1-2 presses) have a 2-second window. Reset actions (4, 5, 8, 10) have a 10-second window.
Wait for completion - After pressing, wait for the device to complete its action. Do not unplug power during operations.
No confirmation prompt - Actions execute automatically after the timeout window. Make sure you press the correct number of times.
