The trial period on a ProxySG can be reset by entering at the CLI the command "reset-trial". This can only be done once and hence will not work if done previously by someone else who has trialed the appliance.
If the command is unsuccessful the owner of the appliance will need to contact Blue Coat and request a evaluation license. They need to fill in the following form located at: https://bluesource.bluecoat.com/evalrequest , or contact their account representative.
