MikroTik Gigabit Ethernet Smart Switch with PoE-out and RouterOS L5 (CRS112-8P-4S-IN)

Great little power house if you need a router and an 8 port POE switch. It's not for a none Mikrotik users. It is not a plug and play unit. You must know about Mikrotiks and how to configure them.

Muy conforme

Mikrotik gear features awesome value for the quality of the hardware, though the software is not nearly as easy to set up as competing options (at much higher price points). The switch / router is very powerful though and what’s extra cool about this fanless little box is that it can power POE devices both at 24VDC as well as 48VDC (though you will have to buy a separate 48VDC PSU for that). One annoying pitfall re the SFP ports is that you should turn off auto-negotiation and instead fix them at 1GbE, as they are otherwise quirky. MikroTik gear is a network engineers dream as they can be programmed to do most anything RouterOS can handle. With RouterOs 7 that includes built in wireguard, opnvpn, etc.

Does it's job and does it well. It didn't care what kind of SPF modules i plugged in, they just worked.

Does not even come close to the speeds they advertise. I had to pull it out due to poor performance.

Does the job and easy to integrate

If you like Mikrotik, you'll like this switch. However it has one glaring issue: it's advertised as a PoE switch, but you have to purchase a separate $60 48V power supply (if you get the OEM one) in order for it to properly provide PoE! The included power supply wont be enough to power a wireless AP, for example. So if you're buying it specifically because it has PoE, the price point is effectively $250 USD or so, not $190-200. It starts to look less compelling vs the competition at that price. Just be aware before you buy this!

We have been using some Mikrotik switches in places where we normally would have used something from Ubiquiti lately after having some issues with Unifi gear in our last few deployments. These take some getting used to, but they seem to be reliable enough and they have lots of non-blocking throughput. Only issue with this unit is that it is marketed as a POE switch, but won't really run any modern POE devices unless you buy the 48VDC PSU, which is like $80 or something. So you can add another hundred bucks to the price of these small Mikrotik switches if you actually need them to work. Can't go wrong with Cisco, but for like, 1/10 the price, Mikrotik gear can usually be made to work.

No venía el soporte para montarse en rack, no lo devuelvo porque me es funcional y me urge pero he notado que últimamente las piezas pequeñas de ciertos pedidos no las envian

Zugegebenermaßen für Neulinge mit RouterOS etwas tricky in der Konfiguration, aber mehr Leistung für Ihr Geld wird man in diesem Leistungssegment kaum finden. Bei diesem Produkt kann man eigentlich kaum etwas falsch machen. Auch die Verarbeitung auf hohem Niveau - nix Billig-Plastik :) Aber bitte bedenken: Konfiguration setzt recht steile Lernkurve voraus!

I have had this switch for many months, and so I have had a lot of time to give it a good test out. I purchased this unit as it had the right feature set and at the right price (or so I thought); I wanted a small manageable switch, with POE. First of all; if you have POE devices that need 48V, you need to purchase another power brick. The brick that comes with this switch does not output the required voltage, and neither does the switch step up the voltage. To make this switch useable for POE+, you need to buy the MikroTik 48V2A96W to go with it which at the time was another £41.00. I was fully aware of this at the time of purchasing, and did buy the additional power brick; though I think it should be an option when purchasing to eliminate waste. Secondly; if you want to do anything beyond just using it as a dumb switch, even things as simple as VLANs, forget it. While it technically can to it, the switch chip on this unit does not support it and so the processing is offloaded to the main CPU, which is weedy. Allocating a single port to a VLAN had a massive performance impact; I would have expected to pass traffic at near wire-speed, but no...throughput drops to about 360Megabits. In conclusion; Mikrotik is well known for making products with good bang for the buck. Every company releases the odd lemon, and this unit certainly is one of those. This switch boasts a great feature set, but does not have the horsepower or right hardware inside to support those features properly. With a decent switch chip, or a processor with some grunt, this switch would be a great piece of kit and at a great price (even taking into account having to buy the extra power pack for POE+). If you do connect any devices to this switch that are passing tagged traffic, it will pass those tags untouched like any other switch, but then that means this is essentially a "dumb" switch with POE; and at £183 (at the time of purchase and with the extra power brick) that is a lot of money. As this unit is really only any good as a "dumb" switch, I would go so far as saying this switch is unfit for purpose and should be withdrawn from sale. If I could, I would be sending this one back.

If you are looking for a 10gbps switch then avoid this one. SFP ports provide optical fiber connectivity options to support uplinks of up to 1 Gbps
