MikroTik 9-Port Desktop Switch, 1 Gigabit Ethernet Port, 8 SFP+ 10Gbps Ports (CRS309-1G-8S+IN)

Just took few minutes to start using the switch. First switched to SwitchOS, then changed management IP to match my needs and that's all. Used Twinax DAC cables of different brands - All worked fine. On the server, had used ASUS XG-C100F.

Come da oggetto, ho trovato l'apparecchio prestazionale e di buona fattura. Non ho a disposizione misurazioni effettive delle velocità di trasferimento dati, ma è silenzioso (il che non è poco) ed, al momento, affidabile

Verwende den Switch Zuhause in meinem lokalen 10-Gigabit Netzwerk. Der Switch funktioniert nach der Einrichtung von SwOS perfekt, allerdings kann die Einrichtung für Anfänger etwas knifflig sein, was aber bei Netzwerk-Equipment logisch ist. Die Preis-Leistung ist grandios und es gibt kaum etwas vergleichbares auf dem Markt. Mein Plan war mein lokales Netzwerk etwas zu verbessern, da wir im Sommer einen 2,5 Gigabit Anschluss bekommen. Mit diesem Switch war das sehr günstig möglich und das Produkt wirkt auch sehr wertig und ist sein Geld mehr als Wert. Die Kompatibilität ist auch sehr gut. Für die LAN Ports verwende ich die Herstellereigenen SFP+ Module (Mikrotik S+RJ10, MikroTik S-RJ01) die ohne Probleme funktionieren. Module anderer Hersteller (10Gtek AXS85-192-M3) funktionieren bei mir auch ohne Probleme und es werden sogar die erweiterten Infos angezeigt (Temperatur, Spannung, Signalstärke, Rauschen usw...). Kann mir nichts besseres vorstellen und werde wahrscheinlich zukünftig auch weiter auf MikroTik SFP+ Switches setzen.

I was adding 10g to my home network, yes I like playing with tech. I needed both fiber and copper. This switch gives the flexibility to have your cake and eat it. Just plug in the SFP+ interfaces you need. I needed three fiber and a couple of copper 10g connections. I get amazing speed with this switch. I use 10g on the computer and 10g (fiber) on my NAS and I get blazing speed. SFP interface are inexpensive and you don't have to use Mirkotik SFP interfaces. I did change the unit from RouterOS to SwitchOS, this is just an option in the web interface and makes the unit easier to use as a switch. UPDATE 01-13-2026 The hardware quality is still amazing with these switches, HOWEVER, be warned that the RouterOS has had a security update. New units ship with a new version of RouterOS that has Severe security. Simple changes, such as changing the switch from running RouterOS to SwitchOS now requires juggling three balls, while doing a tap dance, and singing the Catalina Magdalena Lupensteiner Wallabeiner song. But it's not quite that easy. You have to open a terminal window and do a command line mode change and power cycle the unit (or use the reset Switch, a soft restart will NOT work) within a short time limit, then make the change in the interface and apply, hoping you get it right. Any documentation shipped with the router about this? NO. Any warning in the Interface? NO, just a cryptic error message that the unit can't do the change. I had to look it up on the internet. So when you are first setting up the unit you have to be Next to it, You can't install it then set it up. Fun Times... I understand the need for security, but making a change like this and not including a small slip of paper or a sticker that says "WARNING the software on this unit now had Security changes and you'll have to enable the ability to make changes" would be nice. ALSO being plugged into the Management port on the Switch doesn't make a difference. So why is it called a Management port then? You can't manage the firmware any differently than any other port. Still love the unit though. I have purchased 3 of the 8 port and 3 of the 5 port units and I will continue to purchase more as needed.

Justo lo que necesito. Al ser fanless el truco está en usarlo con SFP de fibra. Los de cobre generan temperaturas insostenibles o que te obligan a dejar bocas sin uso para dar más espacio a la evacuación de calor pasiva. Con fibra el disipador trasero es suficiente.

Suite au passage de ma box internet en 8GB symétrique je voulais en profiter pour augmenter le débit de mon réseau local. C'est chose faite avec ce switch SFP+ auquel j'ai ajouté quelques modules fibre et rj45. L'OS est rustique mais complet, il y a d'ailleurs 2 choix d'OS : un complet livré avec le switch et un plus facile d'accès que l'on peut installer. C'est ce second OS que j'ai installé, n'ayant pas besoin des fonctions les plus avancées de routage proposées par ce switch. Il est maintenant racké dans ma baie 19" avec les équerres fournies. Détail qui peut avoir son importance : une fois le switch allumé une LED bleue assez lumineuse s'allume aussi, suivant où le switch est installé ça peut gêné.
