FAQ
Does Mikrotik RB5009 have WiFi?
The Mikrotik Routerboard RB5009 is an ethernet router and it does not have any wireless radio built into it. Hence it cannot broadcast any WiFi.
What is the default IP address, username, and password for the MikroTik RB5009?
Out of the box, the RB5009 can be accessed via the default IP address 192.168.88.1. The default username is admin, and the password field should be left blank. It is highly recommended to set a strong password immediately upon your first login.
How do I factory reset the RB5009?
To perform a hardware reset, unplug the device, press and hold the reset button, and then plug the power back in. Keep holding the button for about 10 seconds until the user LED starts flashing rapidly, then release it to clear the configuration.
Can I use 1G SFP modules in the RB5009’s SFP+ cage?
No. The SFP+ cage on the RB5009 requires 10G SFP+ modules or compatible 10GBASE-T transceivers. Standard 1G SFP modules are not officially supported and will likely fail to negotiate a link.
Does the 2.5G port support NBASE-T multi-gig standards?
The 2.5G port implements the 2.5GBASE-T standard (IEEE 802.3bz). It does not support 5GBASE-T. For the best interoperability, ensure you are connecting it to a matching 2.5G switch or a standard Gigabit interface.
Can I rackmount the MikroTik RB5009?
Yes. Despite its compact footprint, you can mount up to four RB5009 units side-by-side in a single 1U rackmount space using the optional MikroTik K-79 rackmount kit.
What is the difference between the RB5009UG+S+IN and the RB5009UPr+S+IN?
The key difference is Power over Ethernet (PoE) delivery. The standard UG+S+IN model only accepts PoE-in. The UPr+S+IN model supports both PoE-in and PoE-out on all eight of its Ethernet ports, providing up to 130W of total power budget to run downstream devices like access points and IP cameras.
What power supply options are available for the RB5009?
The indoor models provide excellent redundancy by supporting three different powering methods: standard DC jack, a 2-pin terminal block, and PoE-in (802.3af/at). The router will automatically draw power from the source with the highest voltage.
Can I flash OpenWrt or pfSense on the RB5009?
No. The RB5009 series utilizes an ARM64 processor with a proprietary bootloader and enforced secure boot. It is locked to MikroTik’s RouterOS v7. Operating systems like OpenWrt or pfSense are not supported and cannot be installed.
Does the RB5009 support RouterOS v6?
No, the RB5009 architecture was built exclusively for RouterOS v7. You cannot downgrade the device to v6.
Is the RB5009 powerful enough for 10Gbps routing?
While the router features a 10G SFP+ port, it is designed for environments bridging Gigabit and multi-Gigabit networks. The quad-core 1.4 GHz ARM CPU can easily sustain line-rate forwarding with hardware offloading enabled. However, deep packet inspection, complex QoS queues, or heavy IPsec VPN encryption will heavily utilize the CPU, meaning you will not hit 10Gbps across complex routing tables.
Mikrotik RB5009UG+S+IN Router
Powered by a Quad Core CPU, 1GB RAM, 1GB NAND Storage, Eight Gigabit Ethernet Ports including a 2.5G Ethernet Port, 10G SFP+, a USB 3.0 Port, and a reliable Redundant Power Supply, the Mikrotik RB5009 is the a robust home lab router.

This looks like a very nice Router. The one thing that puts me off is the lack of a 2nd 10G SFP+ port. With that, you could carry your 10G WAN to your 10G CRS326 for example. But of course, you’d have to be able to route that fast. Maybe an upcoming product with more horsepower?
