Abstract
A system and method for remotely powering an Ethernet network repeater through an attachment unit interface (AUI) between the repeater and a remote personal computer (“PC”) or workstation. The AUI includes logic circuitry to detect when the Ethernet is supporting a transmit signal and a receive signal. Associated with the AUI is a DC to DC converter which receives, remotely through the AUI interface, a DC voltage from the PC or workstation and converts the DC voltage into working voltages for the remote repeater.
