MikroTik CRS304-4XG-IN – 4-Port 10G RJ45 Cloud Router Managed Ethernet Switch

The MikroTik CRS304-4XG-IN is a compact, high-performance switch designed to bridge the gap between small-scale deployments and high-bandwidth 10GbE requirements. Featuring four dedicated 10G RJ45 Ethernet ports, this device is engineered for environments where space is at a premium but throughput cannot be compromised. It serves as an ideal top-of-rack solution for small server clusters, a high-speed distribution point for creative studios, or a robust edge device for branch offices. At its core, the CRS304-4XG-IN utilizes a Marvell 98DX226S switch chip, enabling wire-speed performance across all ports without bottlenecking.

A standout feature is its power redundancy; the unit supports four distinct power inputs, including a DC jack, 2-pin terminal, PoE-in, and a USB-C port, ensuring high availability in critical setups. Running on RouterOS v7, it provides advanced Layer 3 routing capabilities alongside its primary Layer 2 switching functions. The fanless, rugged metal enclosure ensures silent operation, making it suitable for office environments while maintaining the durability required for industrial or data center applications. This switch simplifies the transition to 10GbE copper infrastructure without the complexity of SFP+ modules.
