Product Description
CRS304-4XG-IN – Compact 4-Port 10 Gigabit RJ45 Switch
The MikroTik CRS304-4XG-IN is a compact yet highly capable 10 Gigabit Ethernet switch with four ready-to-use 10GbE RJ45 ports — no SFP modules needed. Each port supports 1G/2.5G/5G/10G speeds via standard Ethernet cabling. An additional Gigabit port handles management. The enclosure doubles as a robust lightweight heatsink, eliminating active cooling for silent operation. Four power input options (two DC jacks, 2-pin terminal, PoE-in) ensure power redundancy. DIN rail mount included for versatile placement. Dual-boot RouterOS L5 or SwitchOS.
