As Rob updated check your SMC switch with its inline power capability I will also like to focus on your statement controller never see this lwapp? By this I mean your APs are getting an inline power but they are not seen by controller?
If you switch is 802.3af compliant then can you confirm which vlan your controller management interface is and which vlan your APs are connected? Have you configured SMC switchport as trunk port which is connected to WLC? If the vlans which your AP belongs to is different from controller management interface vlan then have you configured DHCP option 43 or OTAP or DNS? Also which model of APs are connected to SMC switch?
If all these queries which I posted above is already taken care by you then can you post the output of "debug lwapp events enable" from WLC and update the mac addrresses of the APs which are not joining controller?
The ap's are getting power and are operating in stand alone mode (Autonomous). I have other ap's on cisco switches that the controller sees fine (Same network segment not vlans). All of the ap's are LAP1331AG
