Description

1. Port Interface Summary

The “UG+S+IN” suffix defines the port configuration:

• U: USB 3.0 Type-A port

• G: Seven (7) 10/100/1000 Mbps Gigabit Ethernet ports

• S+: One (1) 10/100/1000/2500/5000/10000 Mbps SFP+ cage

• IN: One (1) 10/100/1000/2500 Mbps 2.5 Gigabit Ethernet port (combo port with the SFP+)

Important Note on Combo Port: The 2.5G Ethernet port (eth1) and the SFP+ cage (sfp-sfpplus1) are a combo port. This means only one can be active at a time. You select which one to use in the RouterOS software.

2. Performance Benchmarks (RouterOS v7)

These are approximate real-world routing performance figures.

3. Physical & Environmental

• Dimensions: 195 x 125 x 33 mm

• Weight: 0.78 kg

• Operating Temperature: -40°C to 60°C (-40°F to 140°F)

• Input Voltage: 18-57V DC (Passive PoE-in on Ether1, or terminal block)

• Max Power Consumption: 20W

Key Features and Use Cases

• High-Speed Core Routing: The powerful CPU and 10 Gbps SFP+ port make it ideal for gigabit and multi-gigabit internet connections.

• Hardware Offloading: The CPU features extensive hardware offloading for IPv4 routing, bridge forwarding, VLANs, and IPsec encryption, enabling near-wire-speed performance for these tasks.

• Compact and Silent: Its all-metal, fanless design makes it perfect for office or home environments where noise is a concern.

• Expandable Storage: The M.2 slot allows for adding an SSD to use features like Container, Dude agent, or extensive logging.

• Ideal for: Small/Medium Businesses, Tech-savvy home users, ISPs for customer premises equipment (CPE), Network labs.

Important Considerations Before Buying

1. Passive PoE-IN Only: You must power it with a compatible Passive PoE power supply (like the MikroTik PAR series) or use the separate DC power terminal block. It cannot power other PoE devices like cameras or access points.

2. No PoE Out: If you need to power other devices, you must look at other models (like the RB5009PPr variant) or use separate PoE injectors/switches.

3. Combo Port: Remember you can only use either the 2.5G Ethernet port or the SFP+ port at the same time, not both.

4. RouterOS Learning Curve: MikroTik’s RouterOS is incredibly powerful but has a steeper learning curve than consumer-grade router software. It is configured via WinBox (GUI), WebFig (Web GUI), or a CLI.

The MikroTik RB5009UG+S+IN is widely regarded as one of the best value, performance-per-watt, and future-proof routers in its class.
