MikroTik Cloud Router Switch 4 Port 10Gbps with PoE Input | CRS304-4XG-IN

The MikroTik CRS304‑4XG‑IN is a compact, fanless 10‑Gigabit Ethernet switch featuring four native 10G RJ45 ports and a dedicated Gigabit Ethernet port for management or uplink needs. Powered by a 1.2 GHz dual‑core ARM processor and the high‑performance Marvell Prestera switch chip, it delivers hardware‑assisted switching with support for VLANs, MAC filtering, traffic mirroring, bandwidth control, and limited Layer‑3 offloading. With four independent power input options—dual DC jacks, a 2‑pin terminal, and 802.3af/at PoE‑in—the unit provides robust power redundancy for uninterrupted operation in critical environments. Its metal enclosure doubles as a passive heat sink, ensuring silent cooling and reliable performance across a wide operating range from –40 °C to +70 °C. Offering true plug‑and‑play 10G connectivity without the need for SFP+ modules, the CRS304‑4XG‑IN is an ideal solution for high‑speed server links, workstation clusters, homelabs, and compact enterprise deployments.
