## Overview

The MikroTik CRS305-1G-4S+in is a compact, fanless managed switch featuring one Gigabit Ethernet port and four 10G SFP+ ports. It supports advanced PoE standards and offers dual-boot OS flexibility (RouterOS or SwOS), delivering enterprise-level performance and silent operation in a sleek metal case—ideal for professionals demanding high-speed, reliable networking with customizable control.

## 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: Bought two of these, using one as a router and the other as a simple switch for in-home 10G runs over fibre. The switch was simple to setup, essentially upgrade to the latest firmware and take the defaults as a bridge. Configuring one as a router on the other hand was anything but simple. Finding answers without having to trawl through YouTube was driving me crazy. This little box is a powerhouse, but needs someone with more patience and time to learn than I do. To get my router setup, I followed the example found on GoWifi's website, which was a godsend (I obviously ignored the wifi parts as they were unnecessary here). If you're in the same boat, Google the following: gowifi beginners guide Mikrotik router I don't own a PC, only Mac's so had no choice but to install Wine, and run Winbox.exe to get this done (at one point, you'll have to connect to the device using the MAC address and not the IP address, which is why you need to use Winbox). Other than not understanding where my backups got saved, it now works. Performance wise, as a switch it works great. A router on the other hand isn't recommended for anything except light (real world 330Mbps max throughput) workloads or for temporary use. If it's a router you need, I'd suggest connecting this to the RB5009UG+S+IN instead.
Review: Switching made fast on 10Gbs. Very complete control

## 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.
