| MCN L2- ERROR LED blinking RED IoT2040 USER LED blinking RED | Data loss | MindConnect Nano/IoT2040 was too long offline, so it could not send data to Insights Hub and the storage is full. | - Check outbound connection - Check Ethernet cables - Check Proxy (IP address, User Authentication can be required) |
| MCN L2- ERROR LED RED IoT2040 USER LED | Firmware update error | - Technical problems with a new version of firmware - Incorrect firmware type - Certificate problems, Authentication problems etc. | - Make sure that you are using the correct firmware type (MindConnect Nano/IoT2040). - MindConnect Nano/IoT2040 will automatically restart and then firmware update will be carried out after a while. - If MindConnect Nano/IoT2040 does not restart automatically, then restart it manually: by switching on and off the “power button” on MindConnect Nano and by switching off/on the power supply for MindConnect IoT2040. |
| MCN L3- MAINT LED ORANGE IoT2040 USER LED blinking | Onboarding failed | - Configuration file on the USB stick is invalid - Internal error | - Make sure that the data on the USB stick still is valid. (The data, which you exported to the USB stick, is still valid only for 7 days.). If it is expired, use the asset configuration to export a new valid configuration to your USB stick. - Check asset configuration and reconfigure, if it is required and export a new configuration to USB stick. |
| MCN L3-MAINT LED blinking RED IoT2040 USER LED blinking | - Problems with USB stick - Although no LED lights are shown (except PC ON/WD with constant GREEN) and internet connection is OK, MindConnect Nano still cannot be onboarded to Insights Hub - System Error | - Incorrect formatting of USB stick (no FAT or FAT32) - USB stick is damaged - Write error, USB stick is write-protected or its memory is full. - Configuration file is invalid (damaged, illegible) - See also below Problems with USB stick: - Configuration file in USB stick cannot be read or accepted by MindConnect Nano: - Problems with configuration file - Configuration file is located in an incorrect directory. - Expired configuration file on the USB stick - The configuration file is invalid or not copied to the USB stick Unknown | Check format and partition of the USB stick. It must be FAT or FAT32 formatted and may only contain a single partition. - Try a new USB stick - Remove and plug an USB stick into MindConnect Nano - Check the diagnosis file on the USB stick. - Check the name of the configuration file. It must have MindConnect Nano ID. Do not change the name of the downloaded file. - Check whether the directory is valid. (Configuration file must be in the root directory of the USB stick.) - Make sure that the data on the USB stick is still valid.
