Replace UBNT Toughswitch with RouterOS Device????

Hardware MikroTik hardware general

Hey Folks,

We are looking for a device to replace our UBNT Toughswitch Pros that can run routerOS. Anybody seen anything out there?

We have used the RB750UP, but with VERY limited success, especially when powering more than just a couple of POE devices.


Look forward to any responses!

Did you enable long-cable mode on the 750UP? That seems to come up as the solution to a lot of users’ 750UP questions when the 750UP is powered via PoE anyway.

/int ethernet poe settings set ether1-poe-in-long-cable=yes

Thanks, but yes. The specs simply can not power 5 POE devices, it does not have enough WATT output to do so. Its a real gimmick. Try connecting 4 sxt’s up to it, they will brown out and reboot in cycles, and thats with just 10ft of cable between them.

Tried looking for something Mikrotik based for this for a project last year but in the end I had to use Netonix switches to replace the Toughswitches.

So far so good.

If you are using included 24v 2.5A power adapter, then with enabled “forced-on” mode and ether1-poe-in-long-cable, all powered devices should work stable.

Thanks PaulsMT,

But it does not. Have replicated this with many devices and multiple PowerBOXs.

As the powerbox starts to power port 1, then port 2, etc, as it reaches port 4, port 1 will brown out, then port 5 will power and another random port will brown out, and then this creates a constant cycle. Then any heavy load on the radio of one of the devices will cause a heavy draw in watts, and it will brown out. Simple math of the specs shows that it can not power 4 sxts.

You can state all you would like about the devices I have in stock, but they simply can not be relied upon, they do not function well.

Thanks, those look great! However, I need be able to route with OSPF and I really dont want to introduce a different OS for routing into our network.

Try with 30V 2.5A power supply.

Well, as long as the new device is just acting as a switch, it wouldn’t have any impact on your OSPF.
(assuming it doesn’t cause packet loss or drop multicast frames or anything unusual)

I meant I need to replace toughswitches with a router that can facilitate ospf.

I want to avoid having a poe switch AND a router.

3 options,

  • A) Use a MikroTik with enough ports to do the routing you want + a mid-span PoE injector. The mid-span can be individual single-port injectors or multi-port. Optionally, the mid-span can be manageable.
  • A1) Use multiple MikroTik 750UP type devices and don’t put more watts on any individual 750UP than you feel can be supported on a 750UP. Leave one or more ports empty.
    B) Ubiquity has some multi-port routers which have PoE out ports. You won’t have RouterOS.

C) Use a MikroTik router + PoE capable switch.

Thanks, But thats what we already have. I want routerOS with POE out on mulitple ports that is actually carrier grade, NOT the 750UP.

So, this thread should have been labeled as a feature request?

I think we’ve all been reading it as a design help or tech help request.

14

I see how that could be seen that way. However, I am looking to see if anyone has found a piece of hardware (mikrotik or not) that they use to run POE and routerOS. I don’t think that is so much a feature request.

If you don’t mind to loose poe management, why not just solder the wire in rb750 like this: http://forum.mikrotik.com/viewtopic.php?t=60638&start=50#p448944? It works reliably. Unfortunately you can do it only with 100mbit ports…

I’m powering networks with 750UP, up to 7 switches and NB400+NS2M with original power adapter but I always use the power jack, just split the wires and add a jack.

in 2-3 weeks is the MUM Europe
for sure, will be announced some new products
i hope a bigger poe switch, and I expect at least one gigabit “unifi ac” cAP
