Wired router MikroTik RB5009UPR+S+IN — 8x RJ-45 PoE ports, 2.5GbE, SFP+ slot, RouterOS

The MikroTik RB5009UPR+S+IN is a compact wired router that combines Gigabit and 2.5 Gigabit Ethernet with a 10 Gigabit SFP+ cage for fiber connectivity. It includes eight Ethernet ports with both PoE-in and PoE-out support, a DC jack and a 2‑pin power connector, giving multiple redundant powering options and a durable metallic case suitable for rackmount use.

Advantages

This router provides multiple independent power inputs (PoE-in on all eight ports, DC jack and 2‑pin connector) that accept a wide voltage range (24–57 V) and allow redundant power operation. Each PoE-out port can supply up to 25 W, with a combined PoE budget limited to 130 W. The device prioritizes the highest-voltage source for board power and can automatically fail over to secondary sources. It supports a compact 1U rack deployment (four units in 1U) and integrates high-speed Ethernet and SFP+ fiber connectivity in a small metal enclosure.

Suitable for

• Small and medium ISPs requiring cost-effective edge routing
• Offices and research facilities with limited space
• Environments needing redundant power feeds and PoE distribution
• Rack deployments where multiple compact units are needed

Key specifications

• Ethernet ports: 8 (PoE-in & PoE-out on all ports)

• Processor: 350 MHz (as per product data)
• Internal storage: 1 GB (as per product data)
• USB ports: 1
• Colour and chassis: black metallic case, rackmountable (4 units in 1U)

How to use

Connect fiber modules to the SFP+ cage and attach network cables to the Gigabit and 2.5 Gigabit Ethernet ports. Provide power using any supported input: PoE-in on Ethernet ports, the DC jack, or the 2‑pin connector. Configure the router through its management interface to set power budgets and PoE port priorities if required. The board will select the highest-voltage source for operation and automatically fail over to secondary inputs if a source fails. Reserve at least 20 W for board operation when planning PoE-out power distribution.

Recommendations

Do not mix different input voltages simultaneously; the board will choose the highest-voltage input for powering and allocate PoE-out from the next available source. Manually set port priorities and maximum available power per source when deploying multiple powered devices to ensure stable operation and avoid overloading the combined 130 W PoE budget.
