Updating NDMS online
Updates to NDMS are released regularly, our research and development team are constantly working to make the Netcraze router's operating system faster, more functional and safety-concerned. We recommend using the latest release version available for your Netcraze router.
Important
To update to the latest release of the NDMS online, it is required that the router has a working Internet connection first.
On the 'System dashboard' page of your router's web interface, look for the 'OS version' in the 'About the system' infobox. The operating system automatically checks for the availability of the new releases. When the server has a newer version than the one already running on the device, you will see the 'Update available' status.
Note
Some models are blinking the FN LED on the front panel of the router case when an update availability is detected. That is the default behaviour for this LED, and it can be changed manually to blink the FN LED for a different event.
Click the 'Update available' link. An 'Updates and component options' section of the 'Management' menu will open.
Clicking on the 'Read release notes' link will take you to a page with a description of the release, where you will find the main changes, fixes, new features.
Click on the 'Update NDMS' button to start the OS update process.
Next, a window will appear with a recommendation to save backup copies of the router operating system and settings. We recommend that you always perform a backup before updating the router software (saving the current settings startup-config file and firmware file with the current set of components), which will allow you to quickly restore the current state of the system if necessary.
Then a window will appear with the message 'The device will reboot after installing the updates'. Click 'Confirm'.
Important
During the update process, do not turn off the Netcraze device nor disconnect it from the Internet.
Upon completing the OS update process, the Netcraze will restart automatically and then be ready for use again.
On the 'System dashboard' start page, under 'About the system', verify that the router's operating system has been updated.
Note
Netcraze routers have dual flash memory with active and backup NDMS images to ensure trouble-free automatic updates. The device will first download, save, and verify the integrity of the NDMS image in the backup section without interrupting the main operation. The Netcraze device will then reboot with the updated version of NDMS. Internet access will only be briefly interrupted while your device reboots.
Note
Since version
3.1, the ability to select the NDMS update channel has been added. There are3 channelsavailable:
Main (Recommended): Updates in this channel have been fully tested and are recommended for installation to all users. Official releases are published about every two months.
Preview: By choosing this channel, you can be one of the first to experience the latest updates, performance improvements and new features with minimal risk. Preview versions are released twice a month.
Dev: The test channel is updated weekly and shows our community what we are working on right now. Test builds may contain errors.
Important
Be careful when installing Dev builds! Before installing the NDMS version from the Dev channel, it is recommended to make a backup copy of the current router configuration by saving the startup-config.txt file and the firmware file with the current set of operating system components installed on your Netcraze router. This will allow you to quickly restore the device configuration to its previous state if necessary. Refer to the Updating NDMS by a system file article.
Once you have selected the NDMS update channel and enabled the Automatic updates option, you will only receive automatic updates from the given channel.
On our website, the NDMS Release Notes section provides news on the NDMS releases with a list of major changes relating to Main, Preview and Dev versions.
Functional capabilities of your Netcraze router are determined by the set of installed modules (components of the Netcraze Operating System). You can always change this set by selecting the components you need. More information can be found in the instructions NDMS components installation/removal.
Important
Changing the component set will update NDMS to the latest version.
The ability to install all components that are available for a particular model or a particular specific operating system module combinations at once is not guaranteed.
If, for some reason, the update process of the NDMS has failed for your router, please refer to the Frequently Asked Questions on component installation and NDMS update article.
An online system update can also be performed via the Keenetiс app, available for Android and iOS mobile devices. Detailed information is provided in the article Updating NDMS via the mobile application.
The operating system of the Netcraze device can be updated with a prepared OS image; thus an offline upgrade is possible. To update offline, please follow the Updating NDMS by a system file instructions.
To install a Preview version of NDMS, please follow the Installing a Preview version of NDMS instructions.
To install a Dev version of NDMS, please follow the Installing a Dev bild of NDMS instructions.
