Node and method of controlling devices connected to node
Example embodiments relate to a node and a method of controlling devices connected to the node. In example embodiments the devices may be, but are not required to be, lights.
1. A system comprising:
a network switch;
a first node;
a powered device connected to the first node;
a second node configured to receive an expected signal;
an auxiliary power source; and
a passthrough between the network switch and the first node, the passthrough receiving a first power from the network switch and auxiliary power from the auxiliary power source, wherein the second node controls the passthrough to shunt power from the auxiliary power source to the first node when the expected signal is not received.
2. The system of claim 1 , wherein the network switch includes a plurality of ports and the network switch is configured to distribute power to the plurality of ports.
3. The system of claim 1 , wherein the passthrough comprises a plurality of relays controlled by the second node.
4. The system of claim 1 , wherein the passthrough includes at least one cable directly connecting the network switch to the passthrough, at least one cable directly connecting the auxiliary power source to the passthrough, and at least one cable directly connecting the passthrough to the first node.
5. The system of claim 4 , wherein the auxiliary power source is a second network switch providing the auxiliary power and data to the passthrough.
6. The system of claim 1 , wherein the expected signal is expected to come from the first node.
7. The system of claim 1 , wherein the second node is configured to shunt data via the passthrough to the first node when the expected signal is not received.
8. The system of claim 1 , wherein the expected signal is a heartbeat signal.
9. The system of claim 1 , wherein the passthrough includes a plurality of relays controlled by the second node, at least one cable directly connecting the network switch to the passthrough, at least one cable directly connecting the auxiliary power source to the passthrough, and at least one cable directly connecting the passthrough to the first node.
10. The system of claim 9 , wherein the auxiliary power source is a second network switch.
11. The system of claim 10 , wherein the passthrough shunts data from the second network switch to the first node.
