ᐅ Power Supply at the Main Electrical Connection for Provider – Installation of Server Cabinet

Hello everyone, we are planning to house all the technical equipment in the utility room inside a server cabinet. There is a power strip installed in the server cabinet. Now the question is whether I also need electrical outlets in the area of the utility room where the cables enter. As far as I know, the main distribution points (HÜP) from Kabel Deutschland and Telekom do not require direct power. If amplifiers or other components that need power are necessary, I would have them in my small server cabinet, where all the equipment is actually going to be installed, including the main distribution points. Is this setup feasible? So, placing the main distribution points inside the server cabinet and leaving the cables from the house connection long enough to arrange them inside the cabinet? Thanks.

Oh, I might have expressed myself a bit unclearly. This is a 9U wall-mounted cabinet, so not one of those large freestanding units.

9U will be quite tight. If you haven’t bought the cabinet yet and still have some space, I would consider going for a slightly larger size.

- Patch panel
- Switch
- Power strip
- DSL splitter / router
- Cable connection and distributor?

Then there are also power supplies and cables to consider. If you plan to upgrade in the future with a NAS, a central media PC, IPTV, or something similar, you might run into problems.

9 U (rack units)? What are you planning to do? Switch 1 U, patch panel 1 U, and the other 7 U? Do you have a large 4 U server? And if so, what for? 😀

Oh, 9 U fills up quickly if you’re a bit of a tech enthusiast 😀
I’m planning on a 42-inch (107 cm) floor-standing cabinet. Luckily, my wife isn’t interested in the utility room or everything that happens in there :p

But 9 U should normally be enough. I also installed a 9 U cabinet for my father, which got pretty full with the NAS and so on. In that case, the router just moved onto the cabinet itself (which actually improved the reception).

Do you really mean 42 inches or 42 rack units?

My 42U 19-inch rack is already overflowing, and this winter I’ll have to reorganize and move some equipment into an additional 42U rack. One rack is dedicated just to DSL/LAN, with three 16-port patch panels, the corresponding gigabit switches, a router, and a server with multiple drives acting as a NAS for the family’s video library. The other rack houses the control unit for the home video intercom system, the LAN control module for the heating system (which I separated so I don’t block the boiler), and my alarm system with two 16-channel DVRs handling sensor and analog camera inputs.

Despite cable management, all the wiring still takes up a lot of space, and you want to keep things organized. The worst are the many alarm sensors, which I plan to complement with smoke and gas detectors. My DVR model only supports these through an adapter that has to be wired via screw terminals. I’ve mounted this on a board as a 19-inch module to keep some clarity there. A UPS is also planned, which makes sense with this 12V system.
Since I rewired everything during the house renovation down to the bare walls and ceilings, having the router "locked in" doesn’t bother me. The service technician allowed me to run enough cable so it reaches the rack, where I placed my first telephone outlet. I left a few rack units free between patch panels; otherwise, I’d only be able to access the connecting blocks (LSAs) from the top by removing the entire tray.

Power distribution is also handled via several 19-inch power strips, but I still mounted a small separate outlet strip on the outside wall. I removed the side panel of the rack that sits against the wall so I can access the wall sockets inside the cabinet. All cable feeds come in from that side as well.

If there is space, I believe a bigger rack is the better long-term solution.

Have a great weekend!
