The MikroTik RB5009UG+S+IN is a powerful, compact, and highly versatile wired router designed for heavy-duty use in home labs, small to medium-sized businesses, and ISPs.¹ It's known for its excellent performance in a small form factor, and its ability to fit four units in a single 1U rackmount space.² The "-IN" in the model name specifies a version for the Indian market.

Key Features and Specifications

• Ports: It features nine wired ports in total:³

   

  • 7 Gigabit Ethernet (1G) ports⁴

     

  • 1 2.5 Gigabit Ethernet (2.5G) port⁵

     

  • 1 10 Gigabit SFP+ port for high-speed fiber uplinks.⁶

     

  All ports are connected to a powerful Marvell Amethyst switch chip with a dedicated 10 Gbps full-duplex line to the CPU, preventing bottlenecks.⁷

   

• Processor & Memory: The router is powered by a quad-core 1.4 GHz ARMv8 CPU, with 1 GB of DDR4 RAM and 1 GB of NAND storage.⁸ This hardware combination provides double the performance in CPU-intensive tasks compared to similar MikroTik products. It also has a full-sized USB 3.0 port.⁹

   

• Operating System: It runs on RouterOS v7, the latest version of MikroTik's powerful and feature-rich operating system.¹⁰ This provides a wide range of enterprise-grade functionalities, including advanced routing, firewall rules, VLANs, and IPsec hardware acceleration.¹¹

   

• Powering: The RB5009UG+S+IN has three different powering options for redundancy:

  1. PoE-in from Ethernet port #1 (802.3af/at)¹²

      

  2. A standard DC Jack¹³

      

  3. A 2-pin terminal on the side

• Design & Cooling: The device has a passive cooling system where both the CPU and switch chip are located on the bottom of the board, allowing the metal case to act as a massive heat sink.¹⁴ This fanless design ensures quiet operation.
