ABSTRACT:
A method of ramping up a power supply that supplies power on a communication medium. The method includes supplying power on the communication medium with the power supply operating at a first set point, determining if an overload condition exists, and, if the overload condition does not exist, signaling a first alarm. If the overload condition exists, power is supplied on the communication medium with the power supply operating at a second set point. It is determined if the overload condition continues to exist while operating the power supply at the second set point. If the overload condition continues to exist while operating the power supply at the second set point, a second alarm is signaled.
