recommendations for 2.5 gig 48 port managed switch

Submitted ⁨⁨11⁩ ⁨months⁩ ago⁩ by ⁨ssdfsdf3488sd@lemmy.world⁩ to ⁨selfhosted@lemmy.world⁩

Anybody see a 48 port managed 2.5 Gig ethernet switch for reasonable pricing yet? it seems like these are still either thousands of dollars or sold for chinese market without appropriate certificatiosn to be plugged into the north american electric grid. Any help would be appreciated (even better if it has 2-4 SFP+ 10 gig ports on it)

All I see around is old Cisco enterprise stuff and 1000 would be a low price for that. Not to mention the potential for quite loud fan noise.

2.5 is still really new in the networking space and nobody has hit economies of scale yet. I very much also want to build out my home LAN to be entirely 2.5g compatible, and I only need 16/24 ports. but good God the hardware just isn’t reasonable yet.

You pretty much have to bite the bullet if you really want 2.5 right now. What might honestly be worthwhile is finding a used enterprise 1g switch with the number of ports you need, and will still be “enough”, as those can be had for only a couple hundred dollars. Sit on that for 2-3 years until the 2.5g and 5g hardware market starts to fill out.

  Yeah I would also suggest to stick with 1g switches and if the need for bandwidth is required then create a LAG. 2.5g is currently just finding adoption at this point.

    Oh yeah that’s a good idea too. Sure any one client device will be limited to 1g but your NAS could use a super cheap multi-port ethernet card to get 2 or 4g bonded link speeds so it can serve multiple devices at full speed.

  2.5 and 5 gig are also very much consumer grade speeds, and you don’t really find 48 port consumer grade switches. Enterprises largely don’t give a shit about 2.5 and 5 so there’s no demand to make something like that.

    Yea, I think 2.5G is really searching for a market, that may not exist. For home use, 1Gbit is in general plenty fast enough, and maxes out most US customers Internet too. For enterprise use 10G is common and cheap. The cards to get an SFP+ port into any tower or server is just really small. Enterprise is considering how to do 100G core cheaply enough, and looking for at least 25G on performance servers, if not also 100G in some cases. If you’ve got the budget you can roll 400G core right now in “not insane pricing”.
    
    2.5G to the generic office (that might well be remote) is likely re-wiring and unnecessary. And that’s if you don’t find ac WiFi sufficient, i.e. sub 1G.

If you want decent prices, you will have to look for used 10G SFP+ switches. They will be noisy and I certainly wouldn’t want one in my house though. 2.5G is much more expensive and there isn’t much used equipment available.

You can always trunk 1g connections together. I picked up an old Cisco 3760G poe+ for 20 bucks at the gov surp. Port channels ahoy!

I’d hesitate to call it truly enterprise, but I’ve used the 24 port/10Gbe version of these in a datacenter. Not many issues to write home about - seems to handle vlanning pretty well.

Has 10Gbe uplinks, US power, and PoE+. Probably access to a fancy dashboard too.

$1600 is probably as cheap as you’re getting.
