It is obvious from the specimen configuration that all the modules have sufficient
outputs when an external power supply is used. When a PoE supply is used, the power
output is insufficient for all the modules, which results in automatic decrease in
backlight level, active output current supply, volume and LED intensity. Some modules
need a specific power output for their specific activities: the I/O module, e.g., requires
0.13 W for relay closing (not calculated for minimum consumption).
