## 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 PoE with a DC input voltage of 12-57V, making it versatile for various networking needs. Ideal for small to medium-sized networks, it adheres to IEEE 802.3af and IEEE 802.3at standards, ensuring reliable power delivery and data transmission.

## Long description

The MikroTik CRS305-1G-4S+IN is a compact managed switch with one Gigabit Ethernet port for management and four SFP+ ports supporting up to 10 Gbit each. Housed in a fanless metal case, the CRS305 provides silent operation and includes two DC power jacks for power redundancy. The device supports a Dual Boot option, allowing selection between RouterOS for Layer 3 and routing features or SwOS for a simplified, switch-focused interface.
Advantages
The switch combines high-density 10 Gbit SFP+ connectivity with a dedicated 1 Gbit RJ-45 management port in a small, metal fanless enclosure. Dual DC inputs enable redundant power configurations. Dual Boot lets you choose between full RouterOS functionality or the lightweight SwOS, giving flexibility for different deployment needs. Compliance with IEEE 802.3af/at standards and support for a wide DC input voltage range make it suitable for varied installations.
Suitable for
Small to medium business aggregation and distribution switches
Server or storage uplinks requiring 10 Gbit SFP+ ports
Silent environments where fanless operation is required
Setups needing power redundancy via dual DC inputs
Key specifications
Switch type: Managed
Ports: 4 × SFP+ (up to 10 Gbit each), 1 × Gigabit RJ-45 (10/100/1000) for management
Power: Dual DC jacks, DC input range 12–57 V (supports PoE standards)
10G support: Yes
Networking standards: IEEE 802.3af, IEEE 802.3at
Enclosure: Fanless metal case, white color
How to use
Connect fiber or compatible SFP+ modules to the SFP+ ports for 10 Gbit links and use the RJ-45 port for management access. Supply power using one or both DC jacks to enable redundancy. To select the operating system, use the Dual Boot feature from RouterOS, SwOS or the RouterBOOT loader settings depending on whether you need routing/Layer 3 features (RouterOS) or a simplified switch management interface (SwOS). Configure VLANs, link aggregation or other switch features through the chosen OS interface.
Usage recommendations
For stable 10 Gbit performance use compatible SFP+ modules and quality fiber/copper cabling; when requiring uninterrupted operation, connect both DC inputs to separate power sources for redundancy. Choose RouterOS if you need routing or advanced Layer 3 features, otherwise use SwOS for a streamlined switch configuration.
