MikroTik RB951Ui-2HnD 5-Port Gigabit WiFi 4 Router with PoE

The MikroTik RB951Ui-2HnD is a small-office/home-office wireless access point and router built around a single-core 600 MHz Atheros AR9344 MIPSBE processor with 128 MB of RAM and 128 MB of NAND flash storage. It delivers dual-chain 2.4 GHz 802.11b/g/n (Wi-Fi 4) wireless at up to 300 Mbit/s through integrated 2.5 dBi antennas, while five 10/100 Ethernet ports handle wired connectivity. A USB 2.0 Type-A port with USB Power Reset capability adds peripheral flexibility, and passive PoE output on Ethernet port 5 allows the unit to power a downstream PoE-capable device directly—eliminating the need for a separate injector. Dual power inputs (DC jack and passive PoE-in) both accept 8–30 V, and passive cooling keeps the design silent and maintenance-free. RouterOS license level 4 provides the full-featured routing, firewall, and management capabilities that network professionals rely on for branch, retail, and distributed enterprise deployments.

Key features & benefits

• 600 MHz Atheros AR9344 Processor — The single-core MIPSBE AR9344 CPU delivers the processing headroom needed to run advanced RouterOS features—including firewall rules, routing protocols, and traffic shaping—without performance bottlenecks in typical SOHO environments.
• Dual-Chain 2.4 GHz 802.11b/g/n Wireless — Two antenna chains and Wi-Fi 4 (802.11n) technology combine to reach up to 300 Mbit/s wireless data rates, with built-in 2.5 dBi antennas providing reliable coverage without external accessories.
• Passive PoE Output on Port 5 — Ethernet port 5 outputs passive PoE at the same voltage supplied to the unit (valid input range 18–30 V for this function) at up to 500 mA, allowing a downstream IP camera, access point, or similar device to be powered over the same cable that carries data.
• Flexible Dual Power Input — Both a DC jack and a passive PoE input accept 8–30 V, giving installers the freedom to power the unit from a rack-mount power supply or a PoE injector—whichever suits the deployment topology.
• USB 2.0 Type-A Port with Power Reset — The USB Type-A port supports up to 1 A output and includes a USB Power Reset function, enabling remote power-cycle of connected USB devices through RouterOS—useful for managing LTE modems or other USB peripherals in unmanned installations.
• RouterOS License Level 4 — Included RouterOS license level 4 unlocks a comprehensive set of routing, switching, security, and management features, making this unit suitable for sophisticated network configurations well beyond basic home routing.
• Wide Operating Temperature Range — Tested and rated from -20 °C to +60 °C, the RB951Ui-2HnD performs reliably across the temperature extremes encountered in industrial, retail, and outdoor-adjacent indoor environments.
• Passive Cooling Design — With no moving parts and fully passive thermal management, the unit operates silently and requires no fan maintenance, contributing to an MTBF of approximately 100,000 hours at 25 °C.
