## Summary description

The MikroTik CRS310-1G-5S-4S+IN is a managed L3 network switch designed for efficient data handling. It features Power over Ethernet (PoE) capabilities, allowing for flexible installation and reduced cable clutter. With a 1U rack-mountable form factor, it fits easily into server racks. The switch supports IEEE 802.3af and IEEE 802.3at standards, ensuring compatibility with various devices. Its DC input voltage range is 18 - 57 V, making it versatile for different power setups.

## Long description

The MikroTik CRS310-1G-5S-4S+IN PoE 1U is a managed Layer 3 network switch designed for indoor rack installations where compact, high-throughput fibre connectivity is required. This 1U rack-mountable unit provides five 1G SFP ports, four 10G SFP+ ports and an additional native Gigabit Ethernet port with a direct hardware connection to the switch chip. The device supports Power over Ethernet (PoE-in) and accepts a wide DC input range of 18–57 V, enabling flexible power arrangements in constrained environments. With an ARM v7 CPU, 256 MB RAM and Marvell switching silicon, the CRS310 delivers hardware-offloaded VLAN filtering and partial hardware-offloaded Layer 3 routing, suitable for small offices, ISP access points and branch networks.
Advantages
The CRS310-1G-5S-4S+IN combines multi-gigabit fibre ports and a dedicated Gigabit Ethernet port in a single 1U chassis, reducing the need for additional devices. Hardware offload for VLAN filtering and some L3 routing decreases CPU load and improves throughput for mixed switching and routing tasks. PoE-in capability and a broad DC input range simplify powering in installations where AC outlets are limited or where centralized DC power is used. Rack-mount compatibility and improved cooling make it suitable for continuous operation in standard equipment racks.
Suitable for
 Small and medium ISPs providing 10 Gbps fibre links over distances exceeding 100 meters
 Small office and branch networks requiring consolidated SFP and SFP+ ports
 Upgrading existing CRS212 or similar deployments to add 10G uplinks
 Indoor installations where PoE-in or DC power supply is preferred
Key specifications
 Port count: five 1G SFP ports, four 10G SFP+ ports, one Gigabit RJ‑45 port
 Layer: Managed L3 with hardware-offloaded VLAN filtering and partial L3 routing
 Processor and memory: ARM v7 CPU, 256 MB RAM
 Power options: PoE-in support and DC input range 18–57 V
 Form factor: 1U rack-mountable chassis with improved cooling
 Console access: RJ‑45 serial console port for configuration and management
How to use
Install the CRS310-1G-5S-4S+IN into a standard 1U rack space and connect fibre transceivers appropriate for your SFP and SFP+ modules. Use the Gigabit RJ‑45 port for direct copper uplink or management access where required. Supply power via an appropriate DC source within the 18–57 V range or use a compatible PoE source on the PoE-in capable port. Access the web interface or command-line console through the RJ‑45 console port to configure VLANs, static routes and switching profiles. Apply firmware updates and verify SFP/SFP+ module compatibility before production deployment.
Usage recommendations
For reliable long-distance 10G fibre links, use quality single-mode or multimode SFP/SFP+ transceivers as appropriate for your cabling and distance. Enable hardware-offloaded VLAN filtering for networks with heavy VLAN usage to reduce CPU load. When deploying in racks, ensure adequate airflow and leave space above and below the unit if adjacent devices generate heat. Regularly back up configuration and monitor port status to detect fiber link degradation early.
