2.2. Deploying a Basic PET-7H16M System

Here is a simple application for using the PET-7H16M that is shown below.
There are two ways for the PET-7H16M module getting the power. One is through Ethernet by a
PoE switch; the other is as usual through wiring by an external power. External power should
range from +12 VDC to 48 VDC. The reason we keep the second way is because it might be useful
if someday or somehow you have different applications. PET-7H16M module is equipped with a
LED, which indicates whether the power is supplied by a PoE switch.
