There are holes drilled in the side glass so you can use pvc pipe to and from a container and pump under the tank.
The sump is that containerat the lowest part of the system under the tank.
I guess the auto top off hole is for a tube from an auto top off setup. Which pumps in water when the sump goes below a certain level. To keep the sump/aquarium filled.
