MikroTik CRS304-4XG-IN Overview

Enhance your business by using the MikroTik CRS304-4XG-IN 4-Port 10G Managed Network Switch to expand your network for fast connections to devices and easy file sharing.

Designed for versatility, this switch includes four RJ45 Ethernet ports that can transfer up to 10 Gb/s between compatible network devices. The CRS304 also supports multiple power methods with dual DC adapter inputs for failover redundancy and a 2-pin terminal block. Additionally, the Gigabit Ethernet port may be used for management and for PoE input. A 1200 MHz dual-core processor ensures smooth data transfers while supporting features such as port forwarding, broadcast storm control, and VLANs. This compact switch may be flat or side mounted onto a DIN rail to fit your environment. Or slip it into a backpack to bring the switch with you to different locations. The chassis works as a heatsink, so this fanless managed switch can operate silently in the background. This managed switch uses the RouterOS operating system.

Awesome 10G switch

I have two of these: one from B&H, and one for 1.5 years at this point. The CRS304-4XG-IN switch is an awesome compact 10G switch. While I could use an unmanaged 2.5G switch off Amazon, I wanted something more powerful but also reliable. While I use this like an unmanaged Layer 2 switch, I standardized on MikroTik gear for my wired network, and this is no exception.

Simply works

It is fifth MikroTik device in my house and it works equally well. MikroTik transceivers, including this device, reliably hold 10Gbps link over the older Cat5e cables in my house. The RouterOS is extremely flexible but may feel a bit too much if you only need a simple switch. I believe this model cannot run SwOS yet. Note that the fifth 1Gbps management port is not on the same switch chip with 4 main ports. You still can configure them all in one bridge with VLANs and whatnot. The software will transparently handle it and you get hardware acceleration across the main ports and software handling for the last one. Which may be slower, but it works good enough for me.

The video of the product says that it runs RouterOS and SwitchOS. The text specs mention only RouterOS. Does it run SwitchOS?
Asked by: Timothy
No, the MikroTik CRS304-4XG-IN 4-Port 10G Managed Network Switch runs on RouterOS only.
