Never had one fail ever. Have industrial hardened ethernet ports as well. A bit expensive but worth it

We use the small din rail mounted ones available in 12, 24, and 48 volt power

I want something that *takes* 24V PoE... Not something that *delivers* it.

What about using the switch functionality in MT to turn a router into a glorified switch? Like the RB-493 model for example.

I was going to suggest the 493 as it seems to cover the majority of your needs. It has more ports than the 250, it can run off 24v, there is a version with gigabit ports, and can be managed.

I've started using them at each of my towers, and haven't had any issues so far. I simply bridge the ports and it works. I haven't tried using the switching functionality.

I suspect the 493 would be more rugged, but I probably don't have the load handling requirements you do. Right now, the most I am pushing through any of them is about 30 megs.

What about using the switch functionality in MT to turn a router into a glorified switch? Like the RB-493 model for example. It would make a nice switch with a good pile of ports.

My only worry is that my experience with MT switching on the 450G boards was terrible. They constantly jam up. Apparently it's a known issue with the 450G units, but I don't know about any of the others.

Anyone have experience with other boards than the 450G acting as switches?

I'm looking for a replacement switch to be used on sites.
Currently we're using the RB-250GS units, and they handle like shit for lack of a better description. They are constantly breaking or burning out, jamming, or just doing weird stuff.

It never fails they tend to do it when it's least convenient too.

We have hundreds in service, and while 99% of them are good, the remaining 1% end up kicking us in the face.

Here's where things get tough.
I need it to be powered by 24V PoE. We use the DLI 24V PoE controllers everywhere. I don't want to be doing any conversions if I don't have to. If it has a native 20-30v input of some kind, that I can just grab a takeoff from the DLI unit, that's fine. Wiring contortions don't bother me.

Gigabit switch is not an absolute must but I would prefer it.

Managed is the same deal, I'd LIKE for it to have management but not required.

5 port minimum, but the more the better. I'm cascading 2 usually now.

Thanks!
