1. In a wireless network, a wireless transceiver unit powered by a remote power source via an Ethernet cable and that is not easily accessible, the transceiver unit comprising:
- a detector circuit at the transceiver unit and adapted to detect a reversal in polarity of power via the Ethernet cable from a remote power source; and
a reload circuit coupled to the detector circuit, wherein the reload circuit activates a Reload procedure in the transceiver unit upon the detector circuit detecting the reversed polarity of power, so that the Reload procedure is triggered remotely using the remote power source and without having access to a reload switch at the transceiver unit, wherein the Reload procedure comprises a procedure for reloading default configuration parameters at the transceiver unit.

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.

7. A power source component adapted to be coupled to a wireless transceiver unit that is not easily accessible and that is remotely located from the power source, the power source comprising:
-
a circuit adapted to receive a voltage and output the voltage to a remotely located transceiver unit; and a local switch coupled to the circuit, wherein the circuit reverses a polarity of the output voltage for a desired amount of time upon the local switch being activated, the circuit outputting the reversed polarity voltage to the remotely located transceiver unit, wherein in response to detection of the revised polarity voltage at the remotely located transceiver unit, a Reload procedure is remotely triggered in the transceiver unit in order to reload default configuration parameters. - View Dependent Claims (8, 9, 10, 11)
