Stacked jack assembly providing multiple configurations

A stacked jack multi-port shielded and magnetically conditioned connector assembly is provided for assembly in three distinct configurations. One configuration is where power over ethernet is not required, but rather modular jack contacts are directly connected to a motherboard. A second configuration, the connector assembly can be configured to be enabled to receive conditioned and controlled electrical signals to the connector, whereby power over ethernet may be provided through designated ones of the modular jack contacts. Alternatively, the connector can be configured for an integrated power over ethernet card, where the device is provided as an integrated assembly.
