Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\nFor more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document. \n",

Before a database coming from an untrusted source is loaded into CNM, customers must run the converter. Note that the original database is not modified. So if the original database needs to be loaded once more, it must be converted first.\r\nSTEP 2: Set up the \u201cEdit Password\u201d in the CNM software (https://www.se.com/ww/en/product-range/61527-connexium-network-manager/#software-and-firmware). The \u201cEdit Mode\u201d is enabled by default. Customers must activate the edit protection by switching to \u201cRun mode\u201d before exiting the application.
