The method comprises receiving a request at the IED for the configuration change, wherein the request comprises a configuration change signal. The configuration change signal is received at the IED in response to establishing a connection between an I/O module of the IED and a signalling component. The method further comprises verifying the request automatically by the IED, wherein verifying the request comprises detecting a predetermined signal pattern at the I/O module upon receiving the configuration change signal, wherein the predetermined signal pattern is stored in a memory associated with the IED. In addition, the method comprises enabling the configuration change in response to successful verification of the request by the IED.
