Looking for rackmount switch

[Octopuss]

Eight ports aren't going to cut it anymore with the new server using three ports.
Could anyone recommend me rackmount switch, 16 ports, that is PoE capable? Ideally something that could be gotten second hand for reasonable money, but is not an ancient tech at the same time?

I was primarily looking for switch that has some 2,5/5/10Gbit ports, but these are still pretty rare and expensive as hell, so I'm afraid I'll have to ditch that idea.

Oh and - it has to be super quiet or ideally fanless (if that's possible).

Cheapest if you want to use the 10g is to have one new MikroTik or UBNT

https://www.ui.com/edgemax/edgeswitch-16-xg/

And then go for some version used with poe but only gig ports.

If try to combine all in one unit the cost will be higher since 10G is still not very old so people will sell their used ones.

I don't really want one with ports that can do 10Gbit only. A combined (2,5/5(/10)) speed one, OR just gigabit with PoE if I can't find anything.

The Mikrotik CRS305 has had some 1GbE <-> 10GbE issues. I've heard it's fixed in a recent patch, but... Also, that switch is HW accelerated only at L2. If you do anything L3, you're on the little ARM CPU.

I'm looking at Aruba S2500-48T-4x10G's on eBay. They've gotten quite cheap on eBay, since HPE has a new switch line out. People are dumping them. The crew over at r/homelab seem somewhat keen on them. They reported work rather well, even unlicensed. I'm trying to figure out the IPv6 support, and how loud they are, what fan mods can be done. I don't need any more screaming 1U fans.

I have been quite happy with my HPE 5800X series switch which is a really a re-badged H3C. I am fairly sensitive to noise I this stuff all resides in my home office, it has been fine. They make some gigabit switches that will take add-in cards that have 4 ports of 10G. The only real gotcha is that the power supplies are typically sold separately.

A Dell 5524P gives you 24 ports of GbE with PoE, and two SFP+ ports. You can find them used on eBay for $150 or less. Not going to be silent, though.

 

[Octopuss]

Couldn't find anything thus far (that doesn't cost all the organs).
Looks like one or two SFP+ ports would be handy. Other than that, some 12-16 ports would be perfectly enough.

What is your budget?

 

[Octopuss]

I intend to buy 2nd hand. Let's say $200 equivalent.

 

[l@e]

There are few option basicaly cisco or hp with that price range but mostly only 2 ports sfp+. Other with more still up high prices.

The Dell switch I mentioned in the post right above yours does exactly what you say you want. Oh, that's right, I forgot: you didn't want to see my posts.

 

[Octopuss]

How old models such switches typically are?

 

[Octopuss]

Found D-Link DGS-1510-20, but it only has gigabit regular ports. That won't really help me much.
But multi-gigabit switches cost obscene amounts of money, so I don't know....

The Dell 5524P hits all your points except fanless/noiseless, which is going to be wicked hard to find in a PoE switch handling more than a few ports. You can find replacement fans on eBay that claim to reduce the fan noise. These are awesome at the price.

 

[Octopuss]

Like I said, PoE is not a hard requirement. I just wanted to get rid of the stupid little injector, but I can live with it.

 

[Octopuss]

How bad idea is two switches? Would that bring any problems, be it speed, latency, whatever...?

PoE is pretty awesome. We used to have a 24-port injector which was a real PITA, but after upgrading to a trio of Dell 7048P's we can now just configure any port that needs it for PoE from the command line, no rewiring needed. Mucking about with injectors, even a good quality rackmounted one, sucks.

If you get two of the Dell 5524 switches, they actually stack using an HDMI cable, and for every Dell 5524 in the stack you gain two 10GbE SFP+ ports. You can mix a 5524 and a 5524P to give you some PoE ports and some non-PoE ports. The non-PoE switch is somewhat quieter.

 

[Octopuss]

I looked at the 5524, but I'm scared of the fan. These are almost always like a little Boeing.

No doubt! One of the other things that people frequently don't realize is that injectors have a different cable plant dependency. With a PoE switch, the power is on the regular TX/RX pairs so only 2 pair are actually required. With an injector, the power is on the two off pair so all 4 pair are required. If you have someplace where the extra 2 pair have been nabbed to add a jack without pulling extra cable, you are hosed!
