MikroTik CRS125-24G-1S-IN – 24-Port Gigabit Switch with 1 SFP for SMB Networks

MikroTik CRS125-24G-1S-IN is a Layer 3 managed switch for small and medium offices, featuring 24 Gigabit Ethernet ports and one SFP port, combining advanced switching with full gateway router functionality in a single compact desktop unit. Widely deployed as an all-in-one solution for SOHO networks, it delivers wire-speed Gigabit switching across all ports while supporting internet connectivity via fiber, cable or optional USB 4G modem.

Twenty-four Gigabit RJ45 ports and an SFP port with DDM support cover full office connectivity and fiber uplink in a single device. The microUSB port accepts an optional 4G modem as a primary or backup internet source, making the unit a flexible gateway for locations without reliable fixed-line connectivity. Passive cooling and a 15 W draw under normal operation keep the switch completely silent and suitable for open office environments.

CRS125-24G-1S-IN runs RouterOS level 5, allowing each port to be independently assigned to switching or routing mode without additional hardware. The device simultaneously operates as a gateway, firewall, VPN server and Gigabit switch, eliminating the need for separate networking equipment in small deployments. Management is available via Winbox, SSH and web interface, with PCB temperature and voltage monitoring built in.

Recommended for small offices needing a single device for routing, switching and firewall, for remote locations where 4G USB connectivity serves as a backup or primary internet source, for SOHO networks requiring up to 25 Gigabit ports in one unit, and for MikroTik-managed environments where maximum flexibility between switching and routing functions is a priority.
