The “Under Approval” button was on the first firmware of the EWS5912FP switch as well as on the Neutron switch manual version 1. Its function is to indicate the number of unmanaged Neutron APs discovered on the network and also to add the discovered APs to the Controller.
“Under Approval” has been changed to “AP(s) Detected” on the current Neutron controller graphical user interface and user manual though the function remains the same.
