The MikroTik 5-Port Desktop Switch is a compact yet highly effective addition to any network setup, especially when integrated into a Ubiquiti network environment. Despite its small size, this switch offers reliable performance with five Gigabit Ethernet ports, ensuring fast and efficient data transfer for connected devices. Its straightforward design makes it easy to deploy in various settings, from home offices to small businesses. The switch operates quietly and delivers stable connectivity, complementing Ubiquiti's robust network equipment seamlessly. While it lacks advanced features like VLAN support or PoE, it serves its purpose well by providing reliable network expansion with minimal fuss. For users already invested in a Ubiquiti ecosystem, the MikroTik switch is a practical and cost-effective choice for expanding network ports.

First off, if you are looking for a router: look elsewhere. While this can run routerOS, consider it an in-extremis stopgap solution. The CPU on this thing is a little single core clocked at 800mhz. for a small 100M router, it would be fine, but you will redline it and get well below 1G speeds. If your actual router gets struck by lightning and blows up, this will make do in a pinch, but its not what it's designed for. As a switch however, this thing is fantastic, and the cpu is more than plenty to give you a management interface to configure all the bells and whistles you might expect from a smart switch. For the price(~$150), it can't be beat. Its so cheap, that it is competitive with simple media converters for the speed (and gives extra ports on either end as well). I had one running as a switch for a while, and recently figured out you can split the ports with the port isolation to turn it into a 2 channel media converter with an extra gigabit side tap. Its just a remarkably versatile and useful little device.

I don';t really know where to start, but if I had a way to be the main sales guy for this company in the US, I'd be in good shape/happy! There simply isn't anything even close to this available on the US market right now when you are on a tight budget but still want to have the best 10GBit LAN setup at home or in your small office. I work in a rather large company and have dealt with high level products for many, many years. Switching over to 10Gbe is still quite the undertaking/hurdle for companies (or home network nerds like me) due to price. This device enabled me to create the perfect, load balanced, 10GBe backbone between my NAS, my ESXi development server as well as my gaming rig. - The initial setup is working fine and easy to set up right out of the box, but to get all the features, there is a, still manageable, learning curve. - The RouterOS ROM that comes with the router is amazing ! You'll have a COMPLETELY managed switch/router/bridge with this device, where you can configure everything just how you';d like it. Incl. Firewall, routes, VLANs, OpenVPN Server, NAT, ACL and much more.. whatever you might reasonably want really. - And all of this with a superb GUI as well as SSH enabled command line. I can't really express enough how impressed I am with this device... really keeping in mind how much I paid for it. For the 10GBe PCIe NICs (dual port) I actually went to ebay and bought some used HP cards, which worked perfectly with my NAS vendor as well as my VMware DEV server. Cost me about $30 each. Could not be happier, which I'd have bought the 6/8 port version.

I needed a low cost and _quiet_ 10gig capable switch for solution development. I was familiar with Mikrotik as most of my home network is RouterBoard hardware, and at the price point of this switch there is very little out there. My top requirement was having 10gig SFP+ and being quiet, where most 10gig switches aren't designed for home use and belong in a datacenter as they are rather noisy. I plugged this switch in with a couple of budget cost 10gig SFP+ DAC cables, also purchased from Amazon, into my Intel X722 NICs and immediately got link at 10gig: NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None. The RJ45 gigabit port is perfect to connect to the rest of my network. VLAN tagging is working as expected, once you get accustomed to how Mikrotik does things it isn't too difficult to manage VLANs and other advanced settings. You you can manage the device using WinBox, CLI via SSH, or their WebFig in a browser. Out of the box your easiest bet is to use WinBox as it can discover and talk to the device directly by MAC address, rather than the default IP subnet of 192.168.88.1. Once you are connected, you can add DHCP support so that it can be managed on your network. Go into the IP -> DHCP Client section. Click the "plus", set the Interface field to "bridge", and click OK. The OS will now start using DHCP to set an IP address on the bridge interface. If you want the management interface to be on a specific VLAN, you need to add the VLAN into the Interfaces with the desired VLAN ID list first and then repeat the DHCP client settings but with the name you selected for your VLAN interface.

Needed a switch that could handle multiple fiber connections to other switches. Good price and runs cool. Easy switch-over to SWOS and easy to configure through the web interface.

I got this 4 years ago to connect to one port on a NAS. Now 4 years later I have 4 10GB fiber connections plus 1 GB cable connection. It was a pain in the neck to setup as I remember, for one I didn't understand the device but at the end of the day it was running and hasn't failed. It's connected to other fiber ports from 1 ft away, a switch, then a PC 6 feet away, a NAS 10 feet away and another NAS about 150 feet away. No problems, nice and fast. Just make sure you have AIR space around it for cooling. Good device. It's a winner so far. Would be nice to see one with more SFP+ ports. Update: It's still running good 5 yrs later. Still runs hotter then I care for.

The GUI and CLI are a little more complex than other gear, but it works. Great value for the price.

I had never even heard of MikroTik prior to getting this switch. I just searched for the top rated 10gb capable switch with more than 2 ports and I am quite glad I did. I ordered the 5 port 10gb and 3 RJ45 transceivers so I could connect both my desktop and my Unraid server (both using ASUS XG-C100C 10G cards) to my Qnap TVS-951x NAS, as the NAS had only one 10gb port. I got everything all wired up with cat 7 and was quite happy with the performance right out of the gate, and I figured "it's just a switch, I have tons of those" so I didn't really think or bother to check if the switch even had a web interface. I was doing some diagnostics in which I needed to check something with the connection so I decided to check if there was a way into the switch, which was when I discovered what I now consider to be a hidden gem, the RouterOS software that the switch came with. As I mentioned, I thought it was "just a switch", turns out this thing has an extremely comprehensive and feature-packed operating system, with what seems like every functionality under the sun (from a quick glance over, at least) and tools for everything from email testing and verification to traffic generation. I am quite impressed with what you get for the price. Overall, the only gripe I have about the unit isn't really the fault of the unit, but with the RJ45 transceivers I am using, they were causing the whole setup to get alarmingly warm. Since the switch is a fanless design, that might end up becoming an issue for you. Luckily, it is extremely well ventilated, so as long as whever you are using it has some sort of airflow, it should be fine. Of course, if you are using different transceivers, it should not even be an issue for you. I pointed a small fan at them and everything is perfectly cool now, which I should have done long ago anyways as it is also helping cool the rest of the equipment near it. That said, so far it has been great, and I definitely recommend it.
