Fanless Design, Flexible Power, Four 10G Ports

• 4 × 10GbE ports with full 100/1000/10000 Mbps auto-negotiation on standard RJ45 connectors
• PoE-in support alongside two DC jacks and a 2-pin terminal — four power input options with automatic highest-voltage selection for redundancy
• Fanless, passive cooling via a chassis that doubles as a heat sink, ensuring silent operation in noise-sensitive environments
• DIN rail and screw-mount options for flexible installation in racks, server rooms or compact home setups
• Dedicated management port (1GbE) keeps administrative traffic isolated from production traffic

The CRS304-4XG-IN suits home lab enthusiasts, small offices, and IT professionals who need affordable, silent 10 Gigabit switching without proprietary transceivers or active cooling infrastructure.
