VLANs for Powerconnect 6224 and Unifi

Hello,

I am a newbie to the Powerconnect and VLANs in general, so I'm admittedly looking for some help here.  I have stacked Powerconnects that I'm trying to deploy a new VLAN onto, VLAN 110 (Public_WiFi).  We already have VLANs for the Corporate LAN and VOIP.  I have set all of the ports to either trunked or tagged 
(general mode) and have set up a DHCP Server in pfSense.  I have also configured the Wireless Network in the Unifi controller to enable VLAN 110.  When I try to connect to the Guest Network, it returns with an error of "Couldn't get IP address".  What am I missing?  Do I need to configure DHCP on each switch?

Thanks in advance for your help,

Rob
