ABSTRACT:
The present invention is to provide method and apparatus for adapting a GBIC module to an Ethernet switch capable of outputting one of different voltages in which in a case of the GBIC module coupled to the Ethernet switch, a DC converter of the GBIC module is adapted to lower an input voltage thereof supplied by the Ethernet switch prior to boosting the lowered voltage to an operating voltage required by a GBIC logic circuit of the GBIC module without confirming whether the input voltage has the same value as the operating voltage. Thus, the present invention can prevent the GBIC module from not working due to low input voltage or being damaged due to high current when the GBIC module is coupled to the Ethernet switch.
