From version 1.0.0.44 the following functionality was modified:
Title
Description
Transitioning Between
Modes
Change the functionality when device is transited between modes.
•The current running configuration is automatically saved to local storage. If the
system is switched to unmanaged mode via the Managed Mode button, the
system does not load the saved configuration, but it is still maintained in the
device’s local storage mode
•On PC2616/PC2624/2648 - A transition from Unmanaged or Secure mode to
Managed mode via the use of the Managed Mode button results in the switch
resetting automatically and returning to Managed mode while running the saved
configuration (if no configuration exists, then the default configuration is used).
•On PC2808 Only, Transition from Unmanaged to Managed mode behaves
differently – after mode button is pressed device is automatically configured
with IP address 192.168.2.1 and username admin (no password). User must
connect to the device and select, via Restore Configuration WEBUI page, if
device should return to previously saved configuration, or to default
configuration, or configuration loaded via TFTP. Only after this selection the
device will reboot to managed mode with the chosen configuration.
