CRS304-4XG-IN: compact, quiet, 10G made easy

Meet the CRS304-4XG-IN—a small but mighty 10-Gigabit Ethernet switch that streamlines your setup. Unlike many 10G solutions, this model ships with four ready-to-use 10G Ethernet ports—no extra SFP modules, no fuss, just true plug-and-play. You also get an additional 1G Ethernet port dedicated to management.

Cool, silent, and built like a tank

The chassis doubles as a large passive heat sink, so there are no fans and no noise. Perfect for offices, libraries, studios, or even a bedroom homelab. The sturdy enclosure feels premium, balancing durability with a comfortable, lightweight footprint—at a price that makes sense.

Mount it your way

Installation is flexible:

• Side DIN-rail mount included (and it can be relocated to the back)
• Standard screw points on the rear for effortless wall or shelf installs

Power redundancy, perfected

Keep uptime high with four power input options:

• 2× DC jacks
• 2-pin terminal
• PoE-in

The switch automatically picks the highest-voltage source, ensuring continuous operation without manual intervention.

Small frame, serious features

Driven by a dual-core ARM CPU and a Marvell Prestera switch chip, the CRS304 punches well above its size. Expect:

• Port-to-port forwarding
• Broadcast storm control
• MAC filtering
• VLAN configuration
• Traffic mirroring
• Bandwidth limiting
• Select Layer-3 hardware offload capabilities

Your “backpack server room”

With its tiny footprint and tough build, the CRS304 fits anywhere—on a desk, in a rack, or in your backpack for field work. For network admins who need dependable 10G on demand, this switch is a must-carry.
