I’ve a reasonably simple query that I wasn’t in a position to find a definitive reply to on Google. Would there be any challenge with connecting a device to a PoE change via a PoE injector or would that trigger any issues? My intestine is telling me that the switch would be sensible sufficient to know someway that there’s already energy being supplied and not provide any extra. My concern, nevertheless, is that the change and injector would each supply power to the gadget concurrently and presumably damage it. I guess to give slightly context, I have a system that requires PoE plus (802.3at) however my change is only rated for regular PoE (802.3af). My solution is to attach the system via a PoE plus rated injector into the PoE change in order that it will get the required power. Does this seem like the proper thing to do?
PoE 802.3af (also called PoE or PoE Sort I) was ratified in 2003 and helps a maximum energy consumption of 15.4W. PoE 802.3at (also known as PoE+ or PoE Kind 2) was authorized in 2009 and delivers power as much as 30W. These two PoE standards are compatible with units comparable to IP phones, easy IP cameras, and indoor wireless entry factors. However, with new functions comparable to LED lighting, smart buildings, and the internet of things (IoT), there was a necessity for larger bandwidth and energy supply.
For example of the completely different utility necessities needed for powered gadgets, an IP-based mostly telephone may should be moved around within an office and between cubicles a number of instances all through its life by a typical non-technical worker. In contrast an outside surveillance digital camera will require further environmental protections and can stay stationary after its initial set up by IT employees.
