That’s the third component. That’s an Ethernet cable. And there are different PWE standards out there, and I’d like you to know the standards and the maximum amount of power each standard provides. When I first began working with Power over Ethernet, there was no standard. It was maybe in late 2000 or early 2001. And Cisco had its own proprietary power over Ethernet solution. And it was simply called “Cisco inline power.” And it provided 7.7 watts of power, which was enough to power the Cisco IP phones of the day. Later on, the IEEE standards body came out with some PoE standards. The first was 802 3 AF. And that provided exactly double the amount of power that inline power provided, seven watts, and I don’t think this is a coincidence. And the first IEEE standard was exactly double that at 15 watts. And over time, there was a need to provide more and more power. IEEE became yet an other standard. 802.3 can deliver a maximum of 30 watts of power. At the time of this recording, the eight, two, three - phase batteries could provide up to 100 watts of power. And that’s a look at how we can have something like an Ethernet switch power some of the devices out there with which it connects. If you look at a tree in nature, you’ll notice that, on most trees anyway, the branches just go out and out and out. You don’t have one branch looping back into another branch.And the structure of a tree is really what we want for our layer - two networks. Loops are undesirable in layer - two networks. The reason is that in a routed network where a router is forwarding packets, there is a time value inside the header of those IP packets. And every time it goes t hrough a router, that router is going to decrement the time to live value by one. So if we get stuck in an infinite loop, it will go to zero and time out. However, Ethernet switches do not have the luxury of time to fill, so we do not want a layer in a top ological loop. However, for redundancy, loops are great. That way, if one link breaks, we can have another link take over, so what we can do is use the spanning tree protocol, just like a tree. We want to have a logical topology for our layer - 2 network.
