## Overview

The MikroTik CRS305-1G-4S+in is a compact, fanless managed switch featuring four 10 Gbps SFP+ ports and a 1 Gbps Ethernet management port. It offers dual DC power inputs for redundancy and a unique dual boot system allowing users to select between RouterOS for advanced Layer 3 routing or SwOS for simplified switching. Housed in a sleek metal case, it delivers powerful, silent performance ideal for professional environments seeking high-speed, reliable network expansion.

## Description

The CRS305 is a compact and very powerful switch, with SFP+ ports for up to 10 GB per port. The device has a 1Gbit Ethernet port for access management and two DC connectors for power supply. The device is a very stylish and compact metal case without any fans, for quiet operation. The device has a double boot" system that allows you to choose between two operating systems – RouterOS or SwOS. If you want to have a simplified operating system with only specific switch, use SwOS. If you would like the ability to use routing and other Layer 3 features in your CRS, use RouterOS. You can select the desired operating system from RouterOS, from SwOS or from settings. All the feature set comes with a disruptive price, providing the best price/performance on the market.

Review: Great Value! - 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.
Review: Wonderful little powerhouse of a switch - 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.

## Questions & Answers

**Q: Can you run the ethernet port to another switch or is it strictly for management purposes?**
A: can I use this as two 2.5gb aggregation for my nas and connect to my desktop with 5gb ethernet port?

**Q: Anyone try connecting a 10g RJ45 transceiver in one of these sfp ports?   I'd love to convert 10g fiber to 10g copper ethernet.**
A: I run this switch with three (3)10G RJ45 transceivers (10Gtek for Cisco SFP-10G-T-S Compatible 10GBase-T SFP+ 10 Gigabit RJ45 Copper Transceiver 30-Meter) and one (1) DAC cable (10Gtek 10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU3M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Devices, 3m.  Works like a champ.

**Q: Can i use regular cat7 rj45 cables in the sfp+ to achieve 10gbe speeds, or do i need to use a different cable?**
A: When using RJ45 sfp+ modules, you do not need Cat7 (not technically a US standard anyway).  Cat 6a must be able to carry 10mbit for at least 100M.  Cat 6 has to be able to do at least 55M, longer than any most any home or small business run is going to be.   Cat 5e, while not officially rated, will generally work fine for 10gbit over the length of runs used in homes.

**Q: Can I use this as 1 fiber uplink to data center then the other 3 fiber ports to different buildings and the copper to connect to another switch?**
A: Yes. Just think of it as a switch. All 5 ports are on the same network. I have 2 installed essentially as you described.

### ⭐⭐⭐⭐⭐ Simply blown away. Unbelievable product.
*by M***X on December 5, 2019*

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.
