MikroTik CRS304-4XG-IN 10G Switch — 4 x 10G Ports, Fanless, Layer 3, Dual-Core ARM, PoE-In, Versatile Mounting

MikroTik CRS304-4XG-IN delivers four built-in 10G Ethernet ports for high-throughput environments — plug-and-play connectivity with no additional SFP modules needed. Its fanless architecture uses a large heatsink to keep temperatures down while maintaining completely silent operation, making it well suited for home labs, offices, and other noise-sensitive locations. The unit’s compact, premium chassis offers durability and easy integration into diverse setups, with versatile mounting options for desktop or rack/room use. For reliable power, the switch supports four power input methods (DC jack, 2-pin terminal, PoE-in) and includes automatic power source selection to minimize downtime. Under the hood, a dual-core ARM CPU paired with a Marvell Prestera switch chip enables Layer 3 hardware offloading and advanced network functions such as VLANs and traffic mirroring, providing flexible management for demanding networks.
