Cloud Router Switch 304-4XG-IN
Compact, powerful, and ready to simplify your 10 Gigabit network setups with 4x10G Ethernet ports ready to use out-of-the-box. No extra modules needed!
Introducing the CRS304-4XG-IN – a compact yet highly capable 10 Gigabit Ethernet switch designed to simplify your network setup routine. Unlike typical 10 Gigabit products, the new CRS304 is equipped with four ready-to-use 10 Gigabit Ethernet ports straight out of the box. That’s right – you don’t need any extra SFP modules, just pure plug-and-play! Also, there is an additional Gigabit Ethernet port – for management purposes.
Innovative Design Meets Silent Operation
The CRS304 features an enclosure that doubles as a robust, lightweight heat sink, eliminating the need for active cooling. This fanless design ensures silent operation, making it ideal for any environment where noise is a concern – offices, libraries, or even your bedroom homelab! The sturdy form factor provides a premium feel, balancing comfortable weight and durability, all at an accessible price point.
Versatile Mounting Options
This switch includes a convenient DIN rail mount on the side and standard screw attachment points on the back, allowing for seamless integration literally anywhere. Furthermore, the side DIN rail mount can be moved to the back of the switch.
Multiple Powering Options for Ultimate Reliability
Power redundancy is a key feature of the CRS304. It offers four different power input options: two DC jacks, a 2-pin terminal, and PoE-in. The switch automatically selects the power source with the highest voltage, ensuring uninterrupted operation.
Small frame, Big Game
Powered by a dual-core ARM CPU and the mighty Marvell Prestera switch chip, the CRS304 delivers exceptional performance for its tiny size. Port-to-port forwarding, broadcast storm control, MAC filtering, VLANs, traffic mirroring, bandwidth limitations, and even some Layer 3 hardware offloading – not a problem for the CRS304-4XG-IN!
Your Backpack Server Room
The CRS304’s small form factor and enhanced durability makes it an ideal choice for both stationary and mobile applications. Place it on your desk or keep it in your backpack for on-the go networking – this is a must-have switch for any network administrator.

Works well, 10Gb internet transfer, very good.
One issue is that the switch gets very hot, so I had to buy a small fan to cool down the switch, seems fine now.Other than that no problem

Very impressed by the switch for its price. Ton of features and can act as a router as well if needed. Only drawback is that it gets rather toasty with all 5x10Gb ports used at the same time. Around 60C. Excuse the messy cables haven't got round to cable managing yet 😆
