Which router for our new building?

I have a second question: can I also connect regular LAN ports to a POE switch?

Ah, caution! I have had devices that didn't tolerate that in certain combinations. The devices then became extremely hot at the transformer, which can't be healthy. However, it also depends on the POE standard, etc.

As a rule, you can simply disable the POE function per port on the switch – so yes :)

The DIN 18015-2 does not mention the installation of network cables in empty conduits for nothing. It always depends on whether the standard is included in the contract.

Better to keep in mind right away to make the radii in the bends generous – in case you want to pull in fiber optic cables later ;)

As already written in the other post: Nothing is more future-proof than a sufficiently sized empty conduit!

It is best to consider here right away to design the radii in the curves generously

And I think I have already written here that a full empty conduit is no longer an empty conduit ;-)

And I think I’ve already written here that a full empty conduit is no longer an empty conduit ;-)

And if you pull the CAT cable out beforehand, it’s empty again and you have space for "full" ;)

Thank you for the picture now I understand it is a deep flush-mounted box with a keystone module for LAN connection and a cover plate then on top

I will then tell the electrician that all Sat cables and LAN cables must be laid in the conduit or according to DIN 18015-2

Let's see how he reacts whether he immediately says no problem or nope I won't do it :D

I will then instruct the electrician that all satellite cables and LAN cables must be laid in the conduit or according to DIN 18015-2

Then please say or even better put it in writing: "must be laid replaceable in the conduit"
