I have a 16 port network switch in our media closet and I have run out of ports. Can I just buy a 8 port unmanaged switch and connect it to the 16 port with Cat6? From what I understand that should work without any kind of software setup...but not sure. I know I would use a port on each switch for this but it would net me 6 more ports which is all I think I need. Or should I just buy a 24 port and replace the 16?

It’ll work fine. I have 3 switches setup throughout my house to deal with connectivity. It’s not as good as a patch panel but one day I’ll get around to it.

That's fine joining 2 switches and the most important consideration is to accommodate future expansion.

Yes. Check pricing though, I was able to buy a "used" 48 port switch on Amazon for less than a new 24 port one cost.

As others said, no problem doing that.

I have several smaller switches cascaded from my main switch to specific spots, no issues.

I've got a couple of switches as well as a Ubiquiti wireless router box with 3 ethernet outputs on it on mine. I've got an 8 port straight from the modem, and a few access points and TVs filling that up. Then the line to my box in the office. And another that has some POE cameras connected to it.

Yeah companies dump their old gear on the market when they upgrade and that's what you're buying. It's usually high quality stuff at very low prices, but the downside is a lot of it is meant for datacenters instead of homes. That means they're loud as hell.

And EAT some power. Guzzle that shite

But those decommed Cisco switches can't be beat for how cheap and robust they are

Not all are stupid loud...

Cisco 2960-S 48X1G port (4X1G SFP) draws only 45w under moderate load and is relatively quiet (~34db at 4 feet). They can be had for under $100 all day. The L models are POE and consume close to 100w or more depending on POE loads.

But yes daisy chaining switches is doable.. just keep in mind all the devices on the extended switch will be limited to the 1G backhaul link. (Assuming you are running 1G)

Just going to point out that this is almost certainly not going to cause any sort of bottleneck in a home network environment.

In general, you want the fewest "hops" between devices, but for basically all practical purposes, you're not going to notice a difference in speeds between having a single 1000bit connection and, say, 8 switches between Point A and Point B.


I actually just upgraded my main switch in my house and got rid of a 24-port (non-PoE) linksys. I'm setting it up in my Dad's house- he has 4 or 5 switches in a central closet (over time he added a few devices here/there and it was easy enough to find an old 100base switch lying around here or there)

While you are correct, likely 99% would see no difference.

I tend to forget that my network is so far from 'normal' that I don't even qualify for a copy of the home game.
