Abstract
A system and method to remotely activate a procedure, preferably to Reload, a transceiver unit powered with an Ethernet cable. The system and method includes a power source including circuitry to reverse the polarity of voltage for a desired amount of time to a detection circuit in the transceiver unit. Upon successful detection, a reload circuit preferably in the transceiver unit activates the Reload procedure in the transceiver unit.
