MikroTik RB5009UPr+S+IN Router: ports, hardware and who it suits

The MikroTik RB5009UPr+S+IN is a wired router built for home labs, small offices and anyone who wants more control over their network than a typical consumer router allows. It pairs a four-core processor with a mix of Gigabit, 2.5 Gigabit and SFP+ ports. The listing is short on detail, so this page sticks to what it states and explains what those terms mean.

The processor and memory

The listing describes a Marvell Armada ARMv8 CPU with four cores running at 1.4GHz each, along with 1GB of DDR4 RAM and 1GB of NAND storage. For a router, the processor does the work of moving packets, running firewall rules, and handling things like VPN tunnels and routing. A four-core design generally gives it room to do several of those jobs at once.

The NAND storage holds the operating system and your configuration, in the way a phone stores its software, rather than the large capacity you'd find in a computer.

The ports

The listing's title gives the port layout as seven Gigabit Ethernet ports, one 2.5 Gigabit Ethernet port and one SFP+ cage.

• Gigabit ports suit most wired devices, such as computers, access points and printers.
• The 2.5G port gives more headroom to a device or an uplink that supports 2.5GbE.
• SFP+ is a slot for a small pluggable module. Depending on the module, it can carry a 10 gigabit link over fibre or copper to a switch or server. Modules are sold separately, and compatibility varies, so check what's supported.

The "UPr" in the model name relates to power delivery features on the Ethernet ports. The listing doesn't detail them, so check MikroTik's specification sheet for how the power input and any power-over-Ethernet output work before you plan around them.

RouterOS

MikroTik routers run RouterOS, the company's own operating system. It offers detailed control over routing, firewalls, VLANs, VPNs and traffic management. This control comes with a learning curve. The configuration tools are more technical than the app-based setup on many home routers, and settings are typically adjusted through the WinBox application, a web interface or the command line.

Size

The listing gives the weight as about 1.8 lb and doesn't give the dimensions. A model number in this range is typically a compact desktop unit, but check the official specifications for the exact size and mounting options.

Who it suits

It suits people comfortable with networking concepts: home-lab users, small businesses, and anyone who wants VLANs, detailed firewall rules or a multi-gig uplink. It is a router without built-in Wi-Fi in the listing, so you would add access points separately if you need wireless coverage.

What to check before you buy

• Wi-Fi: the listing doesn't describe wireless, so plan for separate access points.
• SFP+ modules: check which modules and cables work with your other equipment.
• Power and PoE: read the specification sheet for the power input and PoE output.
• Your skills: plan time to learn RouterOS.
• Internet connection: confirm that your provider's connection type works with the ports and your settings.

The short version

• A wired MikroTik router with a four-core 1.4GHz ARMv8 CPU, 1GB of RAM and 1GB of NAND storage.
• Seven Gigabit ports, one 2.5G port and an SFP+ cage.
• Runs RouterOS, with detailed routing and firewall controls.
• Wireless is not described in the listing.
• Best suited to people comfortable configuring a network.
