Bathroom pedastal sink

The drain/trap is leaking. Its hard to get to it so I guess I need to detach the sink from the wall. I see two bolts up high that hold it to the wall. Is there anything in the bottom of the pedastal holding it to the floor that I need to know about? Many thanks

Look inside the pedestal. It may have some bolts to the floor. More often, it is just caulked to the floor. Also, someone may have set the sink in a bead of caulk on top of the pedestal
