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.

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.

Installing fiber optic cabling inside the house doesn't make much sense at the moment, unless you have long distances to cover. With Cat7 or Cat8 cables, you can also achieve 10 Gb network speeds over RJ45 connectors. The network cards aren't expensive and have lower power consumption.
In my setup, the main NAS is connected multiple times (across different networks) via 10 Gb DAC cables. I also have a 10 Gb router.
A few 1 Gb streams can also be handled by a Fritzbox. Honestly, at home it’s quite rare for multiple clients to fully saturate the network.

Place the access points centrally in the living/dining area and upstairs.
You can leave the cables inside the walls unconnected and terminate them on the patch panel. Just make sure not to connect the patch panel ports directly to the switch.
Otherwise, the plan sounds good.

The gray panels are patch panels. If I were you, I would immediately choose a 24-port one for rack mounting.
The small black device is a POE injector from Unifi.
The white box is a NAS (2-bay Synology?).
From the setup, I see only a Fritzbox as the router and one access point, since there is only one injector.
What I see should all be fanless except for the NAS. When installed in a cabinet, it shouldn’t be audible.
I’m currently working on our network for the new house. The current setup looks like this: That really looks neat. As already mentioned, it’s better than what I usually find in most companies :-/
Here is my "small" cabinet. The "large" one is in the basement.
This one is mainly for testing purposes, which is why there are two providers, longer patch cables since things often need to be reconnected, etc.
