The information retrieval unit retrieves the VLAN information DB to discover the tag and port which correspond to the destination address. The middleware server is useful for interfacing a MCU with communication devices including Plain Old Telephone Service telephones, Internet Protocol telephones, and multimedia endpoints and with management applications such as exchange servers and databases. The switch is configured to provide a control signal that deactivates the power converter during the shutdown period, preventing the power converter from providing power to the solid state light unit during the shutdown period.
