The CRS309-1G-8S+ is a very compact, yet powerful networking switch. It has eight SFP+ slots, supporting up to 10 Gbit module in each, which results in a total switching capacity of 162 Gbps and total non-blocking throughput of 81 Gbps. The device also has dual-core 800 MHz CPU, 512 MB RAM, a management Ethernet port with PoE power input, RS232 serial port, a grounding terminal and is capable of dual boot (choose which operating system you prefer, RouterOS, or SwOS). The compact and sleek metallic enclosure also acts as a heatsink, making this device passively cooled - no fan noise and no dust accumulation inside. Special rackmount ears for installing unit into the standard rack are provided.

Browser access interface wasn't connecting to the device, so I connected a laptop to the boot port. Still nothing. Had to install WinBox. Then the router auto configured as a switch, but this POS is still acting as a router. Tried to get all the router settings out, still an unidentified network on my Win 7 laptop, not accepting the IP from MY router.
The User Interface in WinBox is so bad that I can't read the tables because the next columns cover the text. The text is also so tiny that I can't read it properly. My external monitor is a LG 43" 4k display. How bad will it be on a smaller 4k display?!
Pulled up MikroTik's website for a support chat or phone number. Nada! Only a lame user run forum and an email address! So I read through a bunch of topics in the forum but only found config code replies. I'm not going to configure this thing from scratch on this geek level UI, this is well below industry standard! The 3rd party setup videos on YouTube are also a joke, no audio, just screen-share recordings, with bad ratings.
I wasted an entire day pulling an optical fiber cable through the attic and the walls, just for this ""switch"". All for nothing. Now I can start over with a CAT 6a cable, because I'm not going to spend big bucks on another switch with the same features.
This pile of a ""switch"" goes back into its box, and straight to Amazon with a 'false product description' justification for a full refund.
If you want a proper, managed SWITCH that works out of the box, go elsewhere. If you like to fiddle around for days on a bad UI or console, this might be your cup of tea!
I have a ubiquiti USG, 48 port PoE with 2 SFP+ ports and a few APs, what i'm looking to build out is a repurpose of some old and some newer hardware, refreshed, to handle all my media, containers, and lab work. Im looking to build a 10Gb back end storage solution for most of these nodes and this switch I was hoping would fit in.
I spent about 8 hours using this switch and I really only need it to function as a dumb switch. Plug one end into my SFP+ on the ubiquiti and set the whole thing to a storage lan. Well this didn't work out very well. The 2M DAC I ordered here didn't work with my switch and this switch so had to stack the Mikro on top and use a 12" cable. That worked fine. The 2M cable worked fine in a synology with an SFP+ card and plugged to the other SFP+ port. Worked, just fine. No in and out issues at all.
Booting up the Mikro only 6 of the ports would init which I found odd. Their RouterOS to be set to "SwoS" simply doesn't work well, or isn't documented clearly but really I tried everything but the console and I couldn't set it to SwitchOS. Not only that but when I would make some changes the switch would run fine, when I would reboot it to make sure the changes persisted, the switch was not accessible.
If you read around and check the forums there is a whole history of issues and stability problems, with people's switches suddenly not being accessible and that sort of thing, and to me it's just not worth it, for when a ubiquiti XG that has 12 SFP+ AND 4 RJ45 is about 280 more. So what's a headache worth? What's a MUCH better UI worth? What's stability worth? What's a smiley face to your wife and kids worth while working on your network/tech projects? What's ease of use and better dashboard worth? It's worth much more than 280 bucks that's for sure. The only reason I don't give this 1 star is that it seems this works out for some people, but really I'd stay away from it.
