Setup and Installation
The setup of the TPE-S44 is almost non-existent. You simply plug it into power and then connect your networked and PoE devices. At that point you are done.
For the TPE-112GS you have to make sure you select the proper voltage on the side before plugging in your non-PoE device, but otherwise it is a very easy process.
For the TPE-111GI you plug the "brick" into wall power and connect your Ethernet cables.
It is really as simple as that.
