## Summary description

MikroTik CRS310-1G-5S-4S+IN is a managed Layer 3 rack-mount network switch in 1U form factor. It features 1 Gigabit RJ-45 port, five SFP slots and four SFP+ 10G slots, 800 MHz processor, 256 MB RAM and 16 MB flash. Powered by DC or PoE (18–57 V) with up to 20 W consumption. Designed for routing, switching and aggregation in enterprise and ISP networks; operates from −40 to 70 °C.

## Long description

The MikroTik CRS310-1G-5S-4S+IN is a managed L3 network switch designed for indoor rack-mounted installations, providing reliable 10 Gigabit fibre connectivity over distances beyond 100 meters. It combines five 1G SFP ports, four 10G SFP+ ports and one Gigabit Ethernet port, and includes an ARM v7 CPU, 256 MB RAM, improved cooling and Marvell switch chips for high performance. The Gigabit Ethernet port is directly connected to the switch chip and supports PoE-in as an additional power option.
Advantages
The switch offers hardware-offloaded VLAN filtering and some hardware-offloaded Layer-3 routing capabilities, which reduce CPU load and improve throughput for ISP and small office deployments. 1U rack compatibility and robust Marvell switch chips deliver solid performance for aggregated fibre links, while PoE-in support and a direct gigabit link ensure flexible powering and optimal Ethernet speed where needed.
Suitable for
Small and medium ISPs deploying 10G fibre links over 100+ meters
Small office networks needing multi-gigabit uplinks and VLAN segregation
Upgrading existing CRS212 or similar MikroTik setups
Indoor rack-mounted network aggregation and distribution
Key specifications
Model: MikroTik CRS310-1G-5S-4S+IN
Ports: 5 × 1G SFP, 4 × 10G SFP+, 1 × Gigabit Ethernet (PoE-in support)
Switch type: Managed L3
CPU / RAM: ARM v7 CPU, 256 MB RAM
Mounting: 1U rack-mountable
Standards: IEEE 802.3af, IEEE 802.3at (PoE)
How to use
Mount the CRS310 in a 1U rack space and connect fibre transceivers to the SFP / SFP+ slots according to required link speeds. Use the Gigabit Ethernet port for direct switched connections or as a management link; if needed, supply power via PoE-in within the supported voltage range. Configure VLANs and Layer-3 routes through the MikroTik RouterOS or SwitchOS interface to enable hardware-offloaded filtering and routing for improved performance.
Usage recommendations
For stable long-distance 10G fibre links, use compatible SFP/SFP+ modules rated for the distance and fibre type being deployed, keep firmware updated, and configure hardware-offload features to reduce CPU load and latency.
