MikroTik CRS125-24G-1S-2HnD-I 24-Port Gigabit PoE Switch RouterOS

The MikroTik CRS125-24G-1S-2HnD-IN is a Cloud Router Switch that unifies a Layer 3 managed switch, a full RouterOS-powered router, and a 2.4 GHz 802.11b/g/n wireless access point into a single compact desktop unit. Built on the MIPSBE architecture with an AR9344 processor running at 600 MHz and 128 MB of RAM, it runs RouterOS License Level 5, giving network administrators access to advanced routing, firewall, and VPN capabilities alongside dedicated switch configuration menus. The 24 copper Gigabit Ethernet ports plus one SFP cage with DDMI support deliver wire-speed switching for up to 25 Gigabit uplinks, while the integrated dual-chain 2.4 GHz radio provides wireless connectivity without requiring a separate access point. A microUSB port supports optional USB modems for 4G failover or primary WAN connectivity. Passive cooling and a wide 8–28 V DC input range make the unit well suited for small and medium business offices, retail locations, and SOHO environments where rack or desk space and noise are concerns.

Key features & benefits

• Layer 3 Switching and Routing in One Device — Ports operate as a full wire-speed Layer 3 switch by default and can individually be pulled out of the switch fabric and used as routed interfaces, giving administrators granular control over traffic segmentation without additional hardware.
• 24 Gigabit Copper Ports Plus One SFP Cage — Twenty-four 10/100/1000 RJ45 ports combined with a single SFP slot featuring DDMI diagnostics support provide flexible wired connectivity for both copper and fiber uplinks at Gigabit speeds.
• Integrated 2.4 GHz 802.11b/g/n Access Point — The built-in dual-chain Wi-Fi 4 radio delivers up to 300 Mbit/s and 4 dBi antenna gain, eliminating the need for a separate wireless AP in smaller deployments.
• RouterOS License Level 5 — The device runs MikroTik RouterOS at License Level 5, providing access to advanced features including firewall, VPN, bandwidth management, and the dedicated Switch menu for hardware-accelerated switching configuration.
• Flexible WAN Connectivity — The microUSB type AB port supports USB Power Reset and can accommodate an optional USB modem, enabling Ethernet, fiber, or 4G cellular gateway connections to the internet from a single device.
• Wide-Range Passive Power Input — Accepts 8–28 V DC via either a DC jack or Passive PoE input, consumes a maximum of 19 W, and operates with fully passive (fanless) cooling for silent deployment in office environments.
• Extended Operating Temperature Range — Tested ambient operating temperature of -30 °C to 60 °C allows deployment in environments that may experience significant temperature variation, such as utility closets or light industrial spaces.
• Onboard Monitoring — PCB temperature monitoring and voltage monitoring are built in, giving administrators real-time visibility into device health through RouterOS without external sensors.
