Abstract
A transceiver-receiving system, such as a network switch with pluggable transceivers, is built with hardware and machine logic so that power to certain components is turned off when the pluggable transceiver is not present in its plug in slot. The machine logic for handling the turning off an on of power is present on a processor on the board to which the plug-in slot is attached. The other hardware for handling the turning on and off of the power includes a communication line from the plug-in slot to the processor, and a set of switch(es) located on the power path for the component(s) to be turned on and off according to the presence of absence of the transceiver.
