There are many benefits to implementing a PoE system. First is that only one twisted pair cable is needed to carry both data and power. Because CAT-5 cable is readily available and does not require an electrician to install, the benefits include inexpensive installation and easy maintenance and serviceability. With a PoE system, remote locations can be easily powered and serviced with the ability to maximize power efficiency by enabling smart backup response with power priority, dynamic power allocation and graceful shutdown. Firmware can be remotely upgraded via the data connection and power can be cycled to perform a system reset or upgrade. Relocation of equipment also becomes easier since a wall socket is not required to power the device.
