MikroTik CRS125-24G-1S-RM Professional Gigabit Switch for SMB Networks

MikroTik CRS125-24G-1S-RM is a Layer 3 Smart Switch with 24 Gigabit Ethernet ports and one SFP cage, in a 1U rackmount form factor, designed for small and medium businesses that need combined switching and routing capabilities in a single device. It is widely deployed as a primary gateway in SOHO and SMB networks, delivering full Gigabit connectivity with advanced routing features through RouterOS.

The hardware platform features an AR9344 processor at 600 MHz, 128 MB of RAM, and a dedicated QCA8513L switch chip for wire-speed switching across all 24 ports. The SFP port with DDM support enables fiber uplink or long-distance connectivity. Passive cooling and a maximum power draw of 15W make the CRS125 a silent, energy-efficient option for rack deployment in office environments. An MTBF of approximately 200,000 hours reflects long-term reliability in continuous operation.

The device runs RouterOS with a Level 5 license, providing full routing, firewall, VPN, and centralized management capabilities. Ports can be operated in wire-speed switch mode or individually removed from the switch configuration for dedicated routing — essential flexibility for hybrid network designs. Passive PoE IN support (8–28V) and a microUSB port allow alternative power input and connection of an optional 4G USB modem for internet backup.

Recommended for small and medium offices requiring a complete gateway with Gigabit switching, for distributed networks where Layer 3 routing at the access level is needed, for SOHO ISP deployments, and for any infrastructure where consolidating router and switch into one device is an operational priority. The 1U rackmount form factor allows direct integration into standard equipment racks.
