MikroTikCRS310-8G+2S+in

These are nice switches, and are working very well for me. 10G fiber and 2.5G copper without breaking the bank. The RouterOS on them is quite full featured for such a device as well, with several options for how you want to manage it. I like being able to manage it over a webui, but also being able to manage and monitor it via a full featured ssh environment. They handle everything from 10G fiber down to 10Mbit half duplex with no fuss. The LEDs on these things are BRIGHT! The single fan can get loud, but under normal operation is tends to stay throttled down pretty well.

This switch has a pretty steep learning curve but will reward your time and effort. It can do wire speed L3 once configured and even some limited local routing. It’s not a router though, more of a small aggregation switch. I use it to attach my 2.5gbps devices to a 10gb backbone that goes into a router/firewall setup. It is loud with stock fan in swOS but routerOS is much quieter. I replaced the fan with a noctua and now it’s virtually silent. This is a perfect router for people who are looking to step up their homelab setup from a basic one or two switch setup to something slightly faster/larger. I think it’s important to set an expectation for the capability of the device beyond a homelab setup as it is complex to configure and will require time to learn, some customers looking for a plug and play solution will want to look elsewhere.TLDR: GOATed device for small/medium homelab and people who like to learn/tinker. Crazy feature set for the price. Not as plug and play as other options.

Solid managed switch for the price. Higher learning curve compared to other managed switches.Stick with the installed RouterOS. SwitchOS won't allow you to control the fan speed on this device, so it's always loud at 100% and doesn't seem to work well with the SFP+ ports.

This would be a 5 star unit, if it weren't for the fact that it has a fan and a terrible one, as far as noise is concerned. I was warned of that by various reviews on the web and ordered a quieter fan from Noctua ( Noctua NF-A4x20 PWM, Premium Quiet Fan, 4-Pin (40x20mm, Brown) ) to replace the stock fan. I also had to order some different screws (and nuts/washers) to mount the Noctua fan.Like all devices of the Mikrotik CRS series, this unit comes with both RouterOS and SwitchOS. (The CSS series' units only come with SwitchOS.) Mine shipped with SwitchOS 2.16, which had some problems with the SFP+ ports, so I requested a newer version from support, who within one day provided me with version 2.17RC2. That version worked without a problem. If the unit ships with SwitchOS 2.17 or later, that problem should be gone.While I would have liked to use SwitchOS (since it's a bit easier to navigate than RouterOS), the fan settings are minimal to nonexistent, so I switched to RouterOS, which allows for a setting of the default fan speed and a ramp-up temperature.As you can tell, there was quite a bit of trouble initially, but now it works quietly and flawlessly. However I still can't understand why Mikrotik just didn't spend 10$ more on a decent quiet fan and charge more for the unit. This would have made the product so much more appealing. So I'm deducting one star for that nuisance.So if you can do the fan swap yourself, then this is a 4-star unit. If you can't (or are not willing to) do that, then this might only be a 2 - 3 star unit and you shouldn't have it in your living or working area.

Great little SwitchJust using 3 Ports on it for now.Got another device coming for one of the SFP+ PortsLittle noisy on boot. But with only 2x2.5gig and 1 Gig Device Plugged into it it is silent.Box was not sealed when it arrived but everything appeared to be there.Did have to peel of the Front Rubber Feet (to get it into my rack above another switch)

I have two other. Mikrotik switches that are fine. This is a brick after about one week and attempting to run SWos. Winbox, netinstall, serial all failing. Can't get a single port to light up. Not alone in this I've learned.Don't see myself going any further into the Mikrotik ecosystem after this. What a dud. Mikrotik UI is trash for me.

This switch is absolutely phenomenal. It takes a bit of effort to get the switch properly booting into SwOS instead of RouterOS, but it works out of the box, with 10gig sfp+ working flawlessly too.The switch is *noisy*. The cooling fan, especially while under sfp+ load + fully loaded ports is louder than my full 48 port switch, and is also the loudest device on my rack. If the noise isn't a dealbreaker for you, this switch is awesome.

Take note that as a switch its great and YES it has routerOs so it can act as a router but the CPU backplane is only 1.3gb so the second you make it do any routing you destroy the multigig switch capability. Its really sad that they could not take that extra step and have one of the best products on the market for home multigig networking.
