Hello everyone!
I have already looked around the forum a bit to find answers to my (partly more specific) questions about LAN/SAT wiring in a single-family house. However, overall, I didn’t really get the information I needed. Therefore, I would like to explain my situation here in detail, hoping to get some answers to my questions.
Key points:
I am currently planning the LAN/SAT cabling for our single-family house. The rest of the electrical work will be carried out by a professional. To save some money, I want to install the LAN and SAT myself.
Our single-family house has a ground floor (GF), an upper floor (UF), a garage with a workshop, and a small attic. We do not have a basement.
The LAN and SAT outlets should be generously distributed throughout the house and converge in the technical room on the ground floor.
The basic layout should look like in the two attached images.
At the green connection points, one outlet each will be installed (LAN with 2 ports, SAT 1 or 2 ports). The red connection points currently only have cables without outlets and are intended for optional future connections:
In total, the following number of connection points are planned throughout the house:
LAN – GF: 12 connection points (5 with outlets (each with 2 ports), 7 cables only)
LAN – UF: 7 connection points (5 with outlets (each with 2 ports), 2 cables only)
LAN – Total: 19 connection points (10 with outlets (2 ports each), 9 cables only)
SAT – GF: 5 connection points (3 with outlets (one 1port and one 2port), 2 cables only)
SAT – UF: 4 connection points (4 with outlets with 1 port each)
SAT – Total: 9 connection points (7 with outlets (five 1 port, one 2 port), 2 cables only)
All cabling should converge in the technical room and be installed in a server cabinet (19-inch, 12 rack units – RU). This cabinet should ideally be recessed into the wall (then it would be on the other side underneath the stairs).
For LAN, I plan to use duplex CAT7 installation cable, Gigabit 10 Gbit network cable, 1000 MHz shielded twisted pair (S/FTP).
For SAT, I plan to use 135 dB coaxial SAT cable, antenna cable, 4-fold shielded coaxial cable suitable for DVB-S/S2, DVB-C, and DVB-T BK.
All cables (19 duplex LAN = 38 connection points, including those currently only running inside the wall on the opposite side) will then be connected via two 24-port patch panels and a 24-port switch to the Fritzbox (Internet).
From the satellite dish, I want to connect to a multiswitch (inside the server cabinet) and from there to the SAT outlets in the house.

Questions:
- Is it reasonable that everything (2x 24-port patch panels (2 RU), switch (1 RU), telephone system, SAT multiswitch + possibly a second switch + possibly NAS) fits comfortably into a 19-inch server cabinet with 12 RU (it shouldn’t be unnecessarily cramped)? Or would 9 RU even suffice?
- Is it easy to feed the currently 47 cables (19x LAN duplex + 9 coax) into the server cabinet?
- Is there a mounting frame for the SAT distribution equipment designed for installation inside a server cabinet?
- Do I need to worry about overheating? The technical room also contains the main service connection, a washing machine, and a (condensation) dryer.
- Can a 19-inch server cabinet with 12 RU, which is actually intended for wall mounting, be recessed into a wall? I was thinking of simply creating an appropriately sized hole so the server cabinet passes through the wall and protrudes out the other side (this would be no problem since it is under the stairs).
- What is the best way to ground the entire system?
- Is it really necessary to run the cables inside conduits (empty ducts)? Does this method truly allow the cables to be replaced later, or is it usually too difficult in practice to be a viable option? (We are building with a timber frame structure, if that is relevant.)
- Would you recommend installing Wi-Fi access points? If yes, where? I often read "in the ceiling," but I would actually prefer not to do that.
- Would you recommend installing more outlets? Overall, I would still have 10 free ports on the patch panels.

The gray boxes are patch panels. If I were you, I’d go straight for a 24-port one for rack mounting.
The white box is a NAS (2-bay Synology?).
Based on the setup, I only see a Fritzbox as the router and an access point since there is only one injector.
From what I can see, everything except the NAS should be fanless. Mounted in a cabinet, it won’t be audible.
I’m currently working on our network for the new house. The current setup looks like this: For heaven’s sake
The small black device is a PoE injector from Unifi. Does the injector have to be installed “on site,” meaning where the wall outlet ends at the destination?
Or can I use one of these injectors centrally to supply PoE to any ports I want?

Siedle has a VIOP adapter. Just Google Doorcom. There is also a guide on using it with the Fritzbox.I actually found Doorcom already. Apparently, there are different versions like IP 1+n or something... But honestly, that’s where I get stuck. Then it all starts with wiring the door for the door opener and so on. I can somewhat follow the network part, but once it comes to Doorcom in the distribution board, I think that’s beyond me...
If the switch does not support PoE passthrough, the injector must be placed after the switch. Depending on the type of PoE and the cable used, the distance can be up to 100 meters (330 feet). So, in a typical single-family house, this is usually not an issue. You could therefore install the injectors in the rack. A modern access point (NanoHD) typically consumes less than 5 watts.
A single hotspot is not enough if you want fast Wi-Fi throughout the entire house.
However, you have planned several outlets, so expanding the system later will be easy.

Everything was spotted correctly by rick2018.
Definitely use a proper 19" patch panel. I initially started with the two gray pieces and left them as they were for now. The patch cables to the switch are actually too long for my taste, but you use whatever is around.
Currently, there is only one access point running (UniFi Access Point AC lite). That’s enough for one floor in my case. Wi-Fi on the router is turned off.
The NAS has a small fan on the back, but it’s very quiet. You can actually hear the hard drives more.
The POE injector is placed directly between the switch and the respective port on the patch panel. Normally, any network port can be made POE-capable. The end device must also support POE.
