When a PoE device connects to a switch, it does handshaking with the switch on it's initial connection to start the PoE power. In normal PoE equipment there is no danger in connecting a non-PoE device to any PoE port. Among common industrial PoE switch port voltage outputs, 48 volts is the most widely used. This overall capacity is critical because actual power consumption depends on various factors: For example: An Aruba Instant On 1930 24-port switch consumes about 20 watts.
