MikroTik CRS317-1G-16S+RM Managed L3 None 1U Grey Network Switch - Network Switches (Managed, L3, None, Mounting Grid, 1U)

Very good managed switch with 16 SFP+ ports and one GBe. Switch OS is very easy to use. The performance is as advertised, the price is good, and compatibility with various DAC cables, AOC, and optical transceivers is also very good as far as I can judge.So, perfect.... almost. I have two modules which I need to use, one is a NOKIA GPON ONT, and Mikrotik SFP+ to RJ45 - MikroTik S+RJ10. both (especially the ONT) get very hot, up to a level where the device fans spin up and generate considerable noise, unbearable for a home environment. I have found an SFP+ to RJ45 module with a power consumption of 1.6w instead of the more common 2.5w, it hasn't arrived so I can't provide feedback on that.Some suggest fan replacement to Noctua which should reduce the noise levels, however the airflow of the Noctuas is significantly lower than the original, and I am not keen to start fiddling with the standard fans.

Mikrotik are the Best Managed Router and Switch right now. great user features bonding is flawless. Will continue to buy them. If you want only switch features you can keep using RouterOS or boot into Switch OS to make things simpler if thats what you want. Bonding with Layer 3+4 works flawless and the performance is top notch.

Nice and quite 10G switch. I can push 10G line speeds between nodes (Intel x520-DA2 adapters on each end connected with 5m Intel compatible DACs).Running Router OS (switch OS has issues booting, at least on the version I received - seems to not have an IP according their forums, 0.0.0.0 is not legal address :) ). I am not using this in any routing capacity though (I have my "router" configured as a switch, RouterOS seems to work better than SwitchOS). You can use the single RJ45 1G link as an uplink even in RouterOS (this is my uplink to the rest of my 1G LAN).Don't both with link aggregations - 10G single link speed but ~3G with any type of aggregation enabled. From what I gather this is because the single link connections are handled via the ASIC chip (i.e. directly in hardware) but as soon as you bond the connections packets flow though the CPU instead which has been repeatedly reported as maxing out in the 3Gb/s range. My testing seems to confirm this.Minus 1 star for including useless features (why even allow bonding when it slows down the connection to 1/3 of a single link despite having 2+x the link speed, it appears you can actually bond up 8x ports but why?) and for poor QA on their firmware side (seriously, how did the SwitchOS get out of QA with a 0.0.0.0 IP). Definitely lives up to the MikroTik "advice" of get it working the way you want on a specific firmware OS/version and don't touch it - once it works it works well but it's fragile.Overall very pleased, as a home lab user I have need for lots of bandwidth and throughput but enterprise tech is unnecessarily expensive - especially since I don't need five 9's reliability nor 24/7 tech support, I just need the raw compute power. This switch definitely does what I need it to once I got it all configured correctly and learned which features/buttons are functionally "broken".Notes:This fans do spin down all the way when the switch is cool enough (this includes the SPF+ modules not just the CPU/ASIC). If yours are not then check your firmware for updates.If you are using 1G SFP+ modules to connect to RJ45 links you may need to disable auto-negotiation of the link speed and manually set it to full duplex 1Gb/s speed and then re-insert the SFP+ to RJ45 adapter (you do this per port).Also some of the UI elements don't appear that you interact with them - don't be afraid to click everything, especially the rows/cells in the tables and grids. There is a lot more information and settings buried inside each table row and no indication that you are supposed to click the row to access it.

I've been wondering where the breaking point would turn out to be for 10GbE networking to become affordable, and then this rolled around. So far I've had five devices connected at once with no issues with the back-end switching fabric not being able to handle simultaneous 10G streams of traffic, and don't anticipate any coming in the future. For the money this is absolutely unbeatable, just don't expect it to be able to handle a lot of work at L3 or be able to effectively LAG ports together -- this is a simple 10G layer 2 switch, effectively, and it works great for that purpose.

Used for about 18 months until one of the power supplies died. It has 2 internal power supplies which normally output 24V to the main board. When the PSU died, it over-voltaged the logic board, frying it, meaning the redundant power supply was useless. I tried to get warranty support, and the long and short of talking with the seller and MikroTik is -- There is no warranty. They refused to fix or replace it.If you google for MikroTik and power supply issues, you'll find a lot of people complaining about how they fail and the high failure rate. Seems like their stuff that takes DC is pretty reliable, but they don't know how to design AC power supplies.For sure, I'll never buy another AC powered MikroTik product, and because of their lack of warranty, I'll probably never buy another MikroTik product - period.Such potential. Such a waste.

This is Not your Big box store Switch! It is enterprise grade and will takes a lot of knowledge to setup. Does not mean you can not do it! If you can not take the time to learn Networking this is not For YOU!!! There is noting wrong with the software! Like other reviews of the baby switch's say there is... For me as a advanced user it still took me over 5 weeks to setup, after work & weekend's Its in routerOS mode. It will also do Mesh WiFi Network's & cAP Man's. This switch and it's cousins are used by WISP all over the world. For Back End, Long Hall, Point to Point & CPE Equipment. This does have a UI. You will need MORE THEN BASIC NETWORKING SKILLS to get this to WORK!.!. You've been Warned! This Switch has only one con. The Lagg/HA does not work. If you do not know what this is then stop here! This will cause problem's if you want 20Gbps or 40Gpbs on the same Fall over Nic. I am pretty sure they could fix this with software.

The smallest acoustic(noise) 10Gb switch that I've been ever used. but The switch’s setting is very difficult. And SWOS have some noise than Router OS.

Great 10G network switch for a home lab! Easy to set up and works well with Intel or Mellanox cards. Couldn’t recommend it enough!
