Power over Ethernet

[JEDI]

the next big thing since everything is moving towards 'Green' buildings?

worth it to spend time+energy learning it and try to get a job doing it?

<--- not in computer field

The nice thing with POE is you don't need external power for stuff connected at the end point. For example, a wireless AP. Imagine having to put a UPS in the ceiling where the APs are. Instead, the UPS is in the wiring closet and the switch powers the end devices.

At my house I have a POE injector for my wireless AP and if my power goes out I still have wifi access on my phone for several hours.

Well, if you design your space right, your power is all fed from a centralized UPS. Why would you need a local unit?

It's been around for years. And while it makes things much simpler in terms of connectivity (APs, phones, and a few other things), IMHO you're still using the same power. Whether it's from the switch or a seperate brick, the device is still using the power it requires.

There is a certain efficiency gain for using "1 power supply" rather than 44 supplies at IP phones. Is it worth the cost delta for POE gear alone? Not likely.

it's merely simpler to have all ip phones charged via ethernet, then to install mains sockets all over the place. As said prior, PoE is an old protocol.

the next major breakthrough in networking IMO is or should be continental WLANs.

This question is a bit like....

I hear cars are all using fuel injectors. I don't know much about engines, but can I get a job doing fuel injectors?


PoE is a protocol (one of hundreds) that is supported by modern networking architecture. You don't "get a job" in PoE. You can learn the command to enable it as part of a greater knowledge of enterprise switching and routing equipment...


Or you can work handling cabling and running conduit, but the cabling isn't any different for PoE than it is for non-PoE in many circumstances.

PoE depends on needs and budget.

Also future paths of Server/Workstation enviroments will have the workstation (a thin client) powered by it's own Ethernet cable.

 

[DainBrammage]

Anyone who deploys APs that are locally powered deserves EXACTLY what they will get.

Agreed - you don't get a job doing PoE
