Abstract
A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In an enterprise environment, a table top network switch uses a power supply to provide power for PoE and data communications to one or more powered devices (e.g., personal or laptop computers). To reduce the amount of heat generated in the table top network switch, the power supply is located external to the table network switch. The table top network switch may also include enterprise equipment, such as a video projector, a monitor for a personal computing device, another personal computing device to provide some examples. The power supply for the enterprise equipment may be included within the table top network switch to provide additional integration. The power for PoE and data communications to a limited number of powered devices (e.g., personal or laptop computers) may be included within the table top network switch to provide even further integration.
