If one needs around 15 to 20 gigabit ports and a router, then a 12-port gigabit switch added to RB5009 does the trick. Using RB5009 certainly is an option, but paying 200$+ for 9 gigabit ports (OK, one is 10Gbps and one 2.5Gbps) is a bit high. CSS326-24G-2S+RM for example offers more than twice the port count for 2/3 price, something similar having half the number of ports should come with even lower price tag.
Hi,
I would like to use this router to do dual wan failover. is it possible ?
thanks
mkx, pcunite:
Thank you so much for reply.
We have only TP-Link, MaxLink, Ubiquity and Mikrotik FSP in our country…
But Mikrotik have 2 pairs, but I want only one and that’s Ubiquity..But I don’t know, if it will be functional in Mikrotik device.
Optical fibre I search a Ubiquiti Fiber Cable 100 + media convertor also Ubiquity or TP-Link.
But how long the laser works? If the laser is older, is there a problem with max. lenght? Older-less powerfull laser-small distance?
Thank you
12 ports would not fit in the 5009 form factor… they reduced the 10 ethernet ports to 8 to fit into the case.

Well yes when looking only at “price tag”… but realistically you should compare it with CRS326-24S+2Q+ once L3 offloading is supported on the RB5009.
POE version when? We need something to replace the old hex poe
Well, the longevity of SFP modules largely depend on their quality and on actual operating temperature (to lesser extent). So if you intend to operate your link at extreme dustances (ether at very short distances, e.g a few metres or at long distances, close to module specifications), go for high quality modules. If you’re going to operate link at medium distances, then module ageing should not affect the link.
Normal modules should be able to run links for years.
Looks like someone beat me to the idea. MikroTik could really do well with this. They could market it as a “Build-your-own-1U” concept.

This is oil leaking from silicone thermal pad between SFP+ cage and the metal heatsink bottom plate. It is harmless and very common with GPUs. Cheap thermal pads are known to leak oil.
I made a 3d printable rack mount ears for RB5009. Maybe someone will find it useful

I’m wondering how the power on the RB5009 works.
When fed with 48V POE and 24V DC the unit stays powered on when either POE or DC is disconnected, assuming POE is connected first.
However, when fed with 24V DC and POE is provided afterwards, POE doesn’t seem to negotiate PD (softly blinking LED) and thus when the DC jack is removed, the unit only then negotiates POE and starts up again.
When fed with DC through the jack and 2-pin terminal at the same time the unit stays on regardless if one of them loses power, so that would provide redundancy.
Now, if the unit was fed with 48V DC + 48V POE, would it still reboot when power is lost? Or is it still not recommended to feed the unit with the same voltage through multiple inputs (and is this also true for the DC inputs)? Or does the design allow to use the same voltage?
guys hello
i bought 1 RB5009UG+S+IN
the problem that i have is i have 1gbs internet and put it on Wan mikrotik lan My laptop and the speed goes down to 280-300 mbps
i reset the router to default disable all the firewall rules but nothing still the same.
is there a problem with something???
If you use 2.5G port as your wan port, upgrade your RouterOS to the latest version. There is a fix for this problem
*) switch - improved packet forwarding with enabled “cpu-flow-control” setting between different rate interfaces for 88E6393X (RB5009) and 88E6191X (CCR2004-16G-2S+) switch chips
Or, move your wan to other 1G port, see any difference.
Well, it is improvement, as stated in changelog, rather then fix as I see that it’s still not fully 1GB connection: ~800Mbps-930Mbs comparing to 1GB interfaces with stable 940Mbps
Hello,
How can I manage graphs throw firewall? When it’s default config/script it don’t show any graphs, but when I reject script it work..
So is there any firewall setup, how can I enable graphs on ports 2-8?
I want disable only port 1 on graphs. Because it is WAN/internet.
Thanks for help.
I had my my MikroTik RB5009UG+S+in for about 6 months and was flawless, but today all of the sudden it started rebooting every few minutes, 6 times so far in the a row. I think I traced it to out of memory issue.
I tried searching but I calendar 2023 can’t find how to check what’s taking all the disk and RAM space. Any suggestions?
You can use Tools->graphing to graph the memory and disk usage over time, and see if there is a pattern.
Still waiting for +WiFi version of RB5009, any news?
Why ?
AX2 or AX3 are not sufficient ?
RB5009 looks particularly hot … and with 4 antennae would look even hotter. Probably would score a very high value of WAF 
Personally I’d rather see Audience AX … the original Audience is really great device and looks nice as well (passes my better half’s approval process).
Maybe a RB4011iGS+5HacQ2HnD would be something for you? Scores high on the “number of characters in the model name”, has 4 antennas, nice case.
Unfortunately no USB or other storage expandability, and receives little love w.r.t. wave2 support.
