MikroTik CRS310-1G-5S-4S+IN - Managed Layer 3 Network Switch

The MikroTik CRS310-1G-5S-4S+IN is a managed Layer 3 switch featuring one Gigabit Ethernet port, five 1G SFP ports, and four 10G SFP+ ports, designed for fiber aggregation in business networks. It provides fiber connectivity for high-throughput uplinks, while the Gigabit Ethernet RJ45 port handles standard 10/100/1000 Mbit/s copper connections. This allows the device to manage data traffic across multiple fiber links. The switch can be powered via a standard DC jack or through the primary Ethernet port using PoE-in. Support for IEEE 802.3af and 802.3at standards ensures compatibility with existing Power over Ethernet infrastructure.

Designed for standard server enclosures, the unit features a 1U rackmount form factor. Administrators can use web-based management tools to configure network segmentation. The system supports VLANs and includes built-in Quality of Service (QoS) functions to prioritise critical traffic. The device draws 8 W under typical conditions, peaking at 20 W under heavy load. Users can choose between RouterOS v7 and SwitchOS, depending on the required routing complexity. This makes the hardware suitable for ISP setups and office environments that require predictable traffic handling.
