Wired router MikroTik RB5009UG+S+IN — 1x RJ-45, 7x Gigabit copper, 1x SFP+, PoE, DC, 2.5GbE interface, black

The MikroTik RB5009UG+S+IN is a compact, high-performance wired router designed for home labs and small network environments. It combines a Marvell Armada quad-core ARMv8 1.4 GHz CPU with a Marvell Amethyst family switch-chip and an efficient metal case that functions as a heat sink. The board provides nine wired ports (seven Gigabit Ethernet, one 2.5 Gigabit Ethernet, and one 10G SFP+ cage) and a full-size USB 3.0 port, plus 1 GB DDR4 RAM and 1 GB NAND storage.

Advantages

This router delivers nearly double the CPU-load performance compared with similar-form-factor models by using a powerful switch-chip and a quad-core CPU connected via a full-duplex 10 Gbps line. The metal enclosure improves passive cooling by placing the heat-generating components against the case. Multiple powering options (PoE-in on Ethernet port 1, DC jack, and a 2-pin terminal) increase installation flexibility. The device supports standard Ethernet speeds and includes USB 3.0 for expanded connectivity.

Suitable for

• Home lab networks and test environments
• Small office routing and gateway tasks
• Environments requiring mixed 1G / 2.5G / 10G connectivity
• Rack installations where space efficiency is important (up to four units in 1U with optional mounts)

How to use

Install the RB5009UG+S+IN on a flat surface or use the optional mounting accessories for rack installation (up to four units in a single 1U space). Connect your WAN and LAN devices to the appropriate Ethernet ports: use the 10G SFP+ for high-speed uplinks, the 2.5G port for faster-than-gigabit links, and the Gigabit ports for standard connections. Power the device via PoE-in on port 1, the DC jack, or the 2-pin terminal. Access the router’s configuration interface over Ethernet or USB and apply MikroTik RouterOS settings according to your network requirements.

Recommendations

For sustained high CPU loads, ensure good airflow around the device and place the unit so the case can dissipate heat effectively; when using multiple units in 1U rack space, follow the mounting accessory instructions and allow some front-to-back airflow if possible.
