MikroTik CRS304-4XG-IN – 4-Port 10G Multi-Gigabit Switch with RouterOS L5

Description

MikroTik CRS304-4XG-IN is a compact, high-performance multi-gigabit Ethernet switch designed for businesses, internet service providers, system integrators and network professionals who need fast and reliable wired connectivity. With four 10 Gigabit-capable Ethernet ports, a dedicated Gigabit management port and flexible power options, this switch is suitable for upgrading existing networks and building high-speed infrastructure.

The CRS304-4XG-IN combines a compact desktop design with advanced switching capabilities, making it suitable for office networks, server rooms, laboratories, data centres and other environments where space and performance matter. Its lightweight enclosure doubles as a heatsink, providing passive cooling without a fan for quiet operation.

Four High-Speed Multi-Gigabit Ethernet Ports

The CRS304-4XG-IN features four Ethernet ports supporting 1G, 2.5G, 5G and 10G connection speeds. This flexibility allows network administrators to connect compatible servers, workstations, access points, storage systems and switches at the highest speed supported by each connected device.

The four ports can support demanding applications such as high-speed file transfers, network storage, workstation connectivity and uplinks between network infrastructure devices. Actual connection speed depends on the capabilities of the connected equipment, cable quality, cable length and network configuration.

Dedicated Gigabit Management Port

In addition to its four high-speed ports, the CRS304-4XG-IN includes one Gigabit Ethernet management port. This port is useful for device administration, initial configuration and network recovery. Separating management connectivity from the main high-speed switching ports can help simplify deployment and troubleshooting.

RouterOS and Advanced Switching Features

The CRS304-4XG-IN runs RouterOS v7 and has a Level 5 licence. RouterOS provides access to advanced network management features, including VLAN configuration, bridge filtering, traffic monitoring, access control and supported Layer 3 hardware-offloading functions.

The switch uses a dual-core 1.2GHz ARM 64-bit processor, 512MB RAM and 32MB flash storage. Its Marvell Prestera switch chip supports high-performance Ethernet switching. Actual routing performance depends on the selected configuration, enabled features and traffic characteristics.

Flexible Power Options

The CRS304-4XG-IN supports four power-input options: two DC power jacks, a two-pin terminal input and Power over Ethernet input through the management port. The DC jacks and terminal input accept 12–57V DC, while PoE input accepts 36–57V and supports 802.3af/at.

Multiple input options provide flexibility for different installations and can help simplify power planning. The device automatically selects the power source with the highest voltage. Maximum power consumption is 21W, or 15W without attachments. The standard package includes a 48V, 0.95A power adapter and mounting accessories.

Compact, Fanless Desktop Design

The CRS304-4XG-IN measures approximately 176 × 128 × 35mm and uses passive cooling. Its fanless design is particularly useful in quiet offices, small server rooms and other environments where fan noise is undesirable. The enclosure supports a tested operating temperature range of -40°C to +70°C, subject to the manufacturer’s installation and operating requirements.

The device also supports DIN-rail mounting, providing additional installation flexibility for suitable network cabinets and equipment enclosures.

Applications for Business and ISP Networks

The MikroTik CRS304-4XG-IN is suitable for businesses upgrading to 10 Gigabit Ethernet, internet service providers improving network aggregation, system integrators building high-speed LANs and technical teams connecting servers and network storage. It can also be used in advanced home laboratories and small data centre environments where multi-gigabit switching is required.

Before ordering, confirm that the available ports, supported link speeds, power requirements and RouterOS features meet your deployment needs. Remember that the device has four multi-gigabit Ethernet ports and one separate Gigabit management port; it does not have built-in SFP+ or QSFP optical cages.
