The MikroTik RB5009UG+S+IN is a compact yet highly capable router tailored for home labs, enterprise, and ISP environments. It packs powerful performance, a broad set of interface options, and passive cooling—all in a sleek metal chassis designed to fit four units in just a single 1 U rack space.
Key Features & Hardware Specs
- Processor: Marvell Armada ARMv8 (88F7040) quad-core CPU, dynamic frequency from 350 MHz up to 1.4 GHz, optimized for packet processing.
- Memory & Storage: 1 GB DDR4 RAM and 1 GB NAND flash onboard.
- Switch Chip: Marvell Amethyst (88E6393) with a dedicated 10 Gbps full-duplex link to the CPU.
Port & Interface Layout
- Ethernet Ports:
- 7 × 1 GbE RJ45 ports
- 1 × 2.5 GbE RJ45 port
- Fiber Connectivity: 1 × 10 G SFP+ cage
- USB Port: 1 × USB‑A 3.0 with power reset feature (up to 1.5 A)
Powering Options
Supports three redundant power inputs:
- PoE‑in via Port 1 (802.3af/at)
- DC barrel jack
- 2‑pin terminal input (24–57 V)
Maximum power consumption is about 14 W idle, up to 20–25 W under load.
Thermal Design & Form Factor
The CPU and switch chip reside on the underside of the PCB, enabling the robust metal case to act as a heatsink. This passive cooling design eliminates fans and ensures silent operation. Measuring approximately 220 × 125 × 22 mm, four units fit perfectly into a 1 U rack using optional mounting accessories.
Software & Licensing
Runs exclusively on RouterOS v7 with License Level 5, delivering advanced networking features: IPsec hardware acceleration, VLANs, firewall rules, dynamic routing, and more. Enhanced stability is achieved through RouterOS releases (e.g. v7.2+).
