Detection of removable power inlet current rating
View Patent ↗Examples described herein include a removable power inlet, a removable power supply, and an electrical connection between the removable power inlet and the removable power supply. The removable power inlet may send a signal to the removable power supply to indicate an ampere rating of the removable power inlet. The removable power supply may set a current limit on a power supplied from the removable power supply based on the signal.
1. A network device comprising:
a removable power inlet;
a removable power supply;
an electrical connection between the removable power inlet and the removable power supply;
wherein the removable power inlet sends a signal through the electrical connection to the removable power supply indicating an ampere rating of the removable power inlet; and
wherein the removable power supply sets a current limit on a power supplied from the removable power supply based on the signal;
wherein the signal is set to a high signal based on a determination that the removable power inlet unit has a 20 ampere rating.
2. The network device of claim 1 , wherein the network device provides the power supplied from the removable power supply via power over Ethernet.
3. The network device of claim 1 , wherein the removable power inlet comprises a removable DC inlet.
4. The network device of claim 1 , wherein the removable power inlet comprises a removable AC inlet.
5. The network device of claim 1 , wherein the signal is set to low signal based on a determination that the removable power inlet unit has a 15 ampere rating.
6. The network device of claim 1 , wherein the removable power supply comprises an over current protection circuit.
7. The network device of claim 6 , wherein the over current protection circuit sets a current threshold on the power supplied from the removable power supply based on the signal and shuts down the removable power supply based on a determination that the current supplied exceeds the current threshold.
8. The network device of claim 6 , wherein the current protection circuit sets a current threshold based on the signal.
9. A computing device comprising:
a removable power inlet;
a removable power supply electrically connected to the removable power inlet unit;
wherein the removable power inlet comprises an ampere current rating and sends a signal to the removable power supply indicating the ampere current rating;
wherein the removable power supply sets a current limit on a power supplied from the removable power supply based on the signal; and
wherein the computing device supplies the power supplied from the removable power supply using power over Ethernet;
wherein the signal is set to a high signal based on a determination that the removable power inlet unit has a 20 ampere rating.
10. The computing device of claim 9 , wherein the removable power supply is electrically connected to the removable power inlet unit by four conductors.
11. The computing device of claim 9 , wherein the removable power inlet is removable from the computing device separately from the removable power supply.
12. The computing device of claim 9 , wherein the signal indicates a type of current drawn by the removable power inlet.
13. The computing device of claim 9 , wherein the signal is a binary signal.
14. The computing device of claim 9 , wherein the removable power supply comprises an over current protection circuit to set a current threshold based on the signal.
15. A network device comprising:
a removable power inlet;
a removable power supply electrically connected to the removable power inlet unit, wherein the removable power supply comprises an over current protection;
wherein the removable power inlet comprises an ampere current rating and send a signal to the removable power supply indicating the ampere current rating;
wherein the removable power supply sets a current limit based on a power supplied from the removable power supply based on the signal; and
wherein the over current protection sets a current threshold based on the power supplied from the removable power supply based on the signal.
16. The network device of claim 15 , wherein the removable power inlet is removable from the networking device separately from the removable power supply.
17. The network device of claim 15 , wherein the signal indicates a type of current drawn by the removable power inlet.
18. The network device of claim 15 , wherein the network device provides the power supplied from the removable power supply by power over Ethernet.
19. The network device of claim 15 , wherein the removable power supply is electrically connected to the removable power inlet unit by four conductors.
