Planning electrical systems to be future-proof

4 minute rule...

Oh, and look for something where the internal bandwidth fits, I've seen 8-port switches that only have 3gbps internal bandwidth... that probably exists for 24-port ones too... it would be pretty pointless if all ports have 24gbit but the bandwidth is so narrow

Thank you for your detailed and critical feedback, Araknis,
thank you for the concrete recommendation and experience, Reggert. :)

I would also consider which access points you want to use. Ubiquiti or TP-Link offer systems with Unifi or Omada that are easy to install and manage as a whole.

I have the Ubiquiti NanoHDs on the list. However, I am not fixed on them. They have been recommended here several times and I like their appearance.

SFP/UP-Link:

So it’s not really suitable for Fritzbox (especially not for that, since you probably don’t have internet > 1 Gbit/s) or NAS, unless you run out of the other ports. As I said, from SFP+ there is something faster, otherwise only 1 Gbit like the rest.

Can it be summarized like this: If the 24 regular ports are more than enough for me, I don’t need SFP/UP-Link?

If you rely on gut feeling here, you haven’t understood it. Do you want VLANs or routing between VLANs on the switch? STP for example for Sonos needed? A managed switch is obviously not a disadvantage, even if you don’t need the features. It tends to be more expensive, though. Normally, they just run silently out of the box like unmanaged switches as well.

By "gut feeling" I meant that I read through the functions and quickly noted for myself that we don’t need them, unless you see a compelling benefit here. Sorry for the lack of clarity. VLAN is, for example, like using a cannon to shoot our home network sparrow. I’d like to use Sonos someday for the TV and the record player. But that can easily take another 2-3 years.

With switches you just have to make sure that the POE standard matches your access points and yes, the ports usually share the available POE load.

I will post my selection shortly. Would you keep an eye on whether they fit the NanoHDs?

As an affordable 24-port switch I can only recommend the gs1900-24hp because I have the smaller one at home (8hp) and they are available cheaply used and work forever except for the old interface...

I have the successor model (?) on the list. It’s coming now. :)

Here is my initial selection. With name/model/features and price. Unfortunately, links cannot be posted:

1. ZyXEL GS1900-24EP 24 ports, 12 PoE+ 130W, smart/managed, 259 €
2. ZyXEL GS1915-24EP 24 PoE 130W, smart/managed, 299 €
3. TP-Link TL-SG 1428PE 28 ports, 24 PoE, 250W, smart/managed, 277 €
4. Netgear GS324TP 24 ports, 24 PoE, smart/managed 190W, 319 €
5. Netgear GS324PP 24 ports, 24 PoE, smart/managed, 380W, 325 €
6. YuanLey 24 ports, 24 PoE, unmanaged, 400W, 249 €
7. YuanLey 26 ports, 24 PoE, 400W, unmanaged, 170 €

Is there a clear favorite from your perspective for my application or models I should exclude? The YuanLeys were suggestions from the shop and seem very cheap to me. Should these be excluded? Do you have another favorite not on the list?

5. Netgear GS324PP 24 ports, all 24 PoE, smart/managed, 380w, €325

It is unmanaged. Unfortunately, I can no longer correct it above. All are PoE+.

It might be quite good to know which access points you have chosen so that we can see if they work with that :)

I MEAN managed is better because they then have igmp etc., otherwise it can happen that you flood your network with broadcasts and it then becomes slow because the devices don’t know where to send what.
Multicast avoids the problem because it is known where what should go.
Warning, just layman knowledge, I just took it because the price difference was small.

In general, at least with switches, you can always take something used that is a bit cheaper... the average lifespan of switches is 100-300k hours, you will change before that anyway ;)

I would like to take the NanoHD from Ubiquiti.
