## Summary description

The MikroTik CRS305-1G-4S+IN is a managed switch featuring 1 Gigabit Ethernet port and 4 SFP+ ports for high-speed connectivity. It supports Power over Ethernet (PoE) with IEEE 802.3af and 802.3at standards, allowing for flexible installation. With a DC input voltage range of 12-57V, it offers versatile power options. Ideal for small to medium networks, it combines reliability and performance in a compact design.

## Long description

The CRS305 is a compact, fanless metal switch that offers four SFP+ ports supporting up to 10 Gbit per port, a 1 Gbit copper Ethernet port for management, and dual DC power jacks for redundancy. Its small, silent chassis is intended for space-conscious installations that require high-speed fiber or DAC connectivity alongside a dedicated management interface.
Advantages
The switch provides four 10 Gbit SFP+ ports for high-throughput uplinks or server connections while keeping a single 1 Gbit RJ45 port for management access. Dual DC jacks enable redundant power configurations to increase operational reliability. The fanless metal design ensures silent operation and durable construction. A dual-boot system allows selection between a full-featured RouterOS and a simplified SwOS, offering flexibility for either Layer 3 routing or straightforward switching tasks.
Key specifications
Ports: 4 × SFP+ (up to 10 Gbit each), 1 × 1 Gbit copper Ethernet (management)
Power: 2 × DC jacks for power redundancy
Chassis: Fanless metallic case
Operating systems: Dual boot — RouterOS or SwOS
Use case: High-speed switching and optional routing (Layer 3)
How to use
Install SFP+ modules or DAC cables in the four SFP+ ports and connect the 1 Gbit copper port to your management network. Provide power using one or both DC jacks to enable redundancy. Choose the preferred operating system via the RouterBOOT menu or from within RouterOS/SwOS: select SwOS for a simplified switch interface or RouterOS to enable routing and additional Layer 3 features. Configure VLANs, trunking or routing according to your network design using the selected OS interface.
Recommendations
For fiber or direct-attach 10 Gbit connections use compatible SFP+ modules or DAC cables rated for your intended distance and speed. Use both DC inputs when continuous uptime is required and place the switch in a ventilated area despite its fanless design to ensure optimal thermal performance.
