Entering Secure Mode

The Secure Mode page allows you to put the device in the Secure management mode. Once enabled, it prevents users from making any further configuration changes to the switch. This is done by removing the IP address of the switch so that it becomes inaccessible. In Secure Mode the switch retains configuration through power cycles just like in Managed Mode.

To use Secure Mode, configure the device in Managed Mode, and then switch to Secure Mode via the web interface. To exit Secure Mode, press the Managed Mode button on the device to enter the Managed Mode. For information about management modes, see "Management Modes" on page 50. For information about saving Configuration files, see "Managing Files" on page 79.

To open the Secure Mode page, click System → General → Secure Mode in the tree view.
