Purpose of ether port with yellow plug symbol?

Hi,

I have some routerBOARD hardware like that:

On ether1 is POE and I understand this is Power-Over-Ethernet IN.
But what´s the yellow powerplug symbol on Ether10?
And additionally what´s the unlabeled RJ45 port on the backside? Is this for serial console?

Regards
Martin

Yellow ports / ether10 in this routerboard is for PoE OUT.

Note that it is Passive PoE not 802.3af/at standards.

It is useful for, say, powering a Mikrotik wireless device like an inside AP or a roof mounted SXT, without requiring another power point.

Well, you´re absolutely right. It´s even in the verbose description of the router:

I guess I only saw: “PoE out No” in the product specification table.
Thank you!

That looks like a mistake in the specs, Thanks
