[H] My second Ubiquiti Networks Unifi 802.11ac Dual-Radio PRO Access Point

[_ Winterlight]

I purchased a second Ubiquiti Networks Unifi 802.11ac Dual-Radio PRO Access 
Point (UAP-AC-PRO-US), Single,White. I have been using the existing one for the 
last 3 years and I want to put a second one in my back yard.  Once I plug it 
into the existing network will it configure itself as an extender? If not what 
do I have to do to make them work together? Thanks
