SG115 and AP50

I have a SG115 with "UTM Home Use License" at my home. Wondering if I can use an AP50 with my SG115. Eventually how do I connect it to one of the LAN ports on the SG115 or can I connect the AP50 to the separate switch that I have connected to my SG115? I am a newbie, please don't shoot if this questions has been raised before or I am posting in wrong thread. Thanks
