Patent ID: 7508838

Claim:
An Ethernet port apparatus supporting multiple physical media, comprising: a main board means for supporting hot swap and power supply based on a physical medium among multiple physical media and managing the state of the media and performing media exchange by collecting and managing transmission/reception characteristics and states of the physical medium; a detachable physical medium-based sub-board means for generating a control signal based on the physical medium to determine a level of power, transmitting the control signal to the main board means, performing a transceiving function suitable for the physical medium desired by a system user, and informing the state of the physical medium to the main board means; and a physical medium support fixing means 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 means and the sub-board means in order to support multiple physical media transmission interface.
