## Summary description

The Mikrotik CRS305-1G-4S+IN is a managed switch featuring 1 Gigabit Ethernet port and 4 SFP+ ports. It supports Power over Ethernet (PoE) with a DC input voltage range of 12-57V. Ideal for network expansion and efficient power management.

## Long description

The Mikrotik CRS305-1G-4S+IN Gigabit Ethernet PoE is a compact managed switch that combines a single Gigabit RJ-45 port for management with four SFP+ ports that support up to 10 Gbit/s per port. The device supports Power over Ethernet with DC input voltage from 12 to 57 V and includes two DC jacks for redundant power. Housed in a fanless metallic enclosure, the switch is designed for quiet, space-efficient deployment in small racks, server rooms, or network edge locations. A dual-boot feature lets you choose between SwOS for a focused switching interface or RouterOS for advanced Layer 3 and routing capabilities.
Advantages
The switch offers high-speed uplink and aggregation through four 10G-capable SFP+ ports while retaining a dedicated Gigabit copper port for management. Fanless metal housing provides silent operation and improved heat dissipation in compact installations. Dual DC power inputs increase operational reliability through power redundancy. The dual-boot option provides flexibility to use a simplified switching OS (SwOS) or a full-featured routing OS (RouterOS), enabling either straightforward switch management or advanced network functions as needed.
Suitable for
Small to medium office network aggregation and uplinks
Home lab and prosumer network environments with 10G SFP+ devices
Edge deployments requiring silent operation and compact footprint
Installations needing PoE-capable infrastructure with DC power options
Key specifications
Switch type: Managed
Ports: 1 × Gigabit Ethernet (10/100/1000) RJ-45, 4 × SFP+ (up to 10 Gbit/s per port)
PoE and power: DC input range 12–57 V; two DC jacks for power redundancy
Networking standards: IEEE 802.3at, IEEE 802.3af support
Operating modes: Dual boot with SwOS and RouterOS selectable
Enclosure: Fanless metallic case for silent operation
Colour: White
How to use
Connect SFP+ modules or DAC cables to the SFP+ ports for high-speed uplinks and connect the RJ-45 port to a management workstation, router, or access switch. Apply appropriate DC power within the 12–57 V range to one or both DC jacks to enable operation and power redundancy. Use the web interface or Winbox utility to perform initial configuration. Choose SwOS via the boot menu or RouterOS if you require routing, firewalling, or Layer 3 features; the selected OS determines the available configuration options and feature set. Configure PoE and port settings from the chosen operating system interface as required by connected devices.
Usage recommendations
For stable operation, use quality SFP+ modules or compatible DAC cables and provide a reliable DC power source. If you only need switching features, select SwOS for a simpler management interface; choose RouterOS when routing, VLAN routing, or advanced firewall features are required. Place the unit in a ventilated area away from direct heat sources despite its fanless design, and consider redundant power connections for critical deployments.
