Abstract
Provided is an Ethernet port apparatus supporting multiple physical media, a physical medium managing method, and a switching system using the same. The Ethernet port apparatus of the present research can use and manage multiple transmission media by freely selecting and exchanging the transmission media in a system using an Ethernet port. The Ethernet port apparatus supporting multiple physical media, which includes: a main board unit for supporting hot swap and power supply; a detachable physical medium-based sub-board unit for generating a control signal, transmitting the control signal to the main board means, performing a transceiving function suitable for the desired physical medium; and a physical medium support fixing unit for transmitting variable power, a power control signal, a physical medium control signal, a physical medium state information, and physical medium-dependent bitstream between the main board unit and the sub-board unit.
