Effective power management for pluggable transceiver receiving hardware in network switching systems

A transceiver-receiving system comprising:

• a first machine logic module;
• a first receiving connector;
• a first communication line;
• a first power supply;
• a first powered component;
• and
• a first switch;
• wherein:
• the first receiving connector, the first communication line and the first machine logic module are structured, connected and/or programmed to send from the first receiving connector through the first communication line to the first machine logic module, a first signal indicating that a removable transceiver module has been removed from the first receiving connector;
• and
• the first logic module is structured, connected and/or programmed to, in response to receipt of the first signal, control the first switch to turn off so that a flow of power from the first power supply to the first powered component is stopped.
