Switch de red Mikrotik CRS304-4XG-IN 10G Ethernet Power over Ethernet blanco

The CRS304-4XG-IN is a compact 10 Gigabit Ethernet switch with four built-in 10GbE ports ready for immediate use and one additional Gigabit Ethernet port for management. The device is fanless with an enclosure that serves as a heat sink, offering silent operation and a durable, lightweight form factor suitable for office, lab, or portable setups. The switch supports multiple mounting options and several power input methods for flexible deployment and reliable operation.

Advantages

The CRS304-4XG-IN provides plug-and-play 10 Gigabit connectivity without the need for SFP modules, a silent fanless design thanks to a heat-sink enclosure, and a compact robust housing that balances weight and durability. It offers flexible mounting (DIN rail or screw mount) and multiple power inputs including PoE-in, enabling power redundancy and automatic selection of the highest-voltage source.

Key specifications

• 4 × built-in 10 Gigabit Ethernet ports (no SFP modules required)
• 1 × Gigabit Ethernet management port
• Fanless design with enclosure acting as heat sink
• Dual-core ARM CPU with Marvell Prestera switch chip
• Multiple power inputs: two DC jacks, 2-pin terminal, PoE-in; automatic highest-voltage selection
• Mounting options: side DIN rail (relocatable to back) and standard screw points
• Layer 2 features: VLANs, MAC filtering, broadcast storm control, port-to-port forwarding, traffic mirroring, bandwidth limitations

How to use

Place the CRS304-4XG-IN on a desk, mount it on a DIN rail or attach it using the rear screw points. Connect 10GbE cables directly to the four built-in 10 Gigabit ports and use the Gigabit port for management as needed. Provide power via one of the available inputs (DC jack, 2-pin terminal, or PoE-in); the device will automatically use the highest-voltage source when multiple inputs are present. Configure network features such as VLANs, MAC filters, traffic shaping, and mirroring through the switch management interface to match your deployment requirements.

Recommendations

For mobile or compact installations, use high-quality short 10GbE cables and secure the preferred power source to ensure stable operation. When deploying in noise-sensitive environments, take advantage of the fanless design and place the switch where airflow around the heat-sink enclosure is not obstructed.
