MikroTik CRS304-4XG-IN Compact 4-Port 10G Ethernet Switch
Product code: CRS304-4XG-IN
The MikroTik CRS304-4XG-IN is a compact, fanless managed switch that delivers four ready-to-use 10 Gigabit RJ45 Ethernet ports without requiring separate SFP modules.
Use the CRS304-4XG-IN for high-speed workstations, servers, storage, homelabs, offices and compact network cabinets that need quiet, flexible 10G connectivity.
Four 10G RJ45 ports
Connect copper Ethernet devices at 1, 2.5, 5 or 10 Gbit/s with no additional transceiver modules.
Quiet fanless cooling
The durable enclosure doubles as a large passive heat sink for silent, maintenance-free operation.
Flexible redundant power
Two DC jacks, a 2-pin terminal and 802.3af/at PoE-in provide four power-input options with automatic highest-voltage selection.
Powerful switch platform
A dual-core 1.2 GHz ARM64 processor and Marvell Prestera switch silicon support VLANs, traffic control and Layer 3 hardware offloading.
Ideal applications
- 10 Gigabit desktop, workstation and server connectivity
- NAS and high-speed storage networks
- Quiet office, studio and homelab switching
- DIN-rail or wall-mounted equipment installations
- Portable network administration and temporary 10G deployments

Why choose the CRS304-4XG-IN?
The CRS304-4XG-IN delivers practical copper 10 Gigabit connectivity in a compact, silent enclosure. Its four multi-gigabit RJ45 ports avoid the cost and complexity of separate optical modules, while flexible powering and mounting options make it equally useful on a desk, in a cabinet or on a DIN rail. RouterOS v7 provides advanced switching and network-control features when a simple unmanaged switch is not enough.
Frequently asked questions
Does the CRS304-4XG-IN need SFP+ modules?
No. Its four high-speed interfaces are RJ45 Ethernet ports ready for copper network cables.
Which Ethernet speeds do the four main ports support?
Each main RJ45 port supports 1, 2.5, 5 and 10 Gbit/s operation.
Can the switch be powered by PoE?
Yes. The MGMT/BOOT Gigabit Ethernet port accepts 802.3af/at PoE-in at 36–57 V. Two DC jacks and a 2-pin terminal provide additional power options.
Is the CRS304-4XG-IN fanless?
Yes. The enclosure acts as a passive heat sink, allowing silent operation without a cooling fan.
How can the CRS304-4XG-IN be mounted?
It supports wall mounting and DIN-rail mounting. A fastening set with DIN mount is included.
