Does anyone know of an Ethernet hub or switch that can be powered from Power Over Ethernet? I have a location with no electric power but with a Ethernet wall socket. This would allow me to extend the network there without having to invest in an electrician and opening walls etc.
Thanks.
Morning Jan,
Again, do check the local building and safety regulations before choosing a solution.
yes, yes, we do not want cables to burn in walls. Messy.
The other (separate Gigabit) TP-Link devices TL-POE150S (injector) and TL-POE10R (splitter), mentioned earlier in my second post, do seem to be IEEE 802.3af compliant.
I saw that too.
Thanks for thinking with me! Much appreciated.
Eric,
If you want a small remote Gigabit switch, powered directly by PoE, Netgear GS105PE could perhaps be worth a closer look.
Hi jan,
had a look at the manual and it states:
The configuration utility is installed on your computer and is supported only on Windows computers.
So this means not working with a Mac.
Apparently (page 7 in https://www.netgear.com/images/datasheet/common/202-11700-01-WebManagedSwitches- UM.pdf), you could use the web-based configuration as an alternative (and that should work with a Mac).
Had not seen this, thanks.
There is a tragic flaw in what you are proposing. Gigabit Ethernet REQUIRES the use of all eight conductors -- otherwise it falls back to 100Base-T. So there are no spare wires you can use to provide the power.
I recommend you use a regular extension cord, not the Ethernet wiring, to provide power to the Switch.
Hello Grant,
Various PoE devices are marketed as Gigabit (see, for example, http://content.us.dlink.com/wp-content/uploads/2015/11/DPE-301GI-GS_REVA_DATASHE ET_1.00_EN_US.pdf mentioned above). I do not know any details about how these or similar devices work. However, an article https://en.wikipedia.org/wiki/Power_over_Ethernet at least indicates that a phantom technique can be used in certain cases.

Thanks Grant, for taking the time, I did not realise it used all pairs.
Hi Jan,
I did not know that either so thank you for clearing that up for us. I am still not sure how to solve my challenge but this helps.
