Re: [AFMUG] Mikrotik / Mimosa Ethernet Errors
It was definitely the surge suppressor. I took the one out of in-line at the bottom and errors went away. I had tried to put one up top, but couldn't get the A5 to even power up with it inline, so there isn't one present up there anyhow. Now, how do I determine which version I'm getting? I have a few of the earlier versions sitting around that it appears are not going to work well for this application. Strangely, I have a Ceragon running gigabit through the same version with no problems at all. -Jason On Sat, Jun 9, 2018 at 6:55 PM, Chuck McCown wrote: > Surge suppressors can certainly cause this. > > Sent from my iPhone > > > On Jun 9, 2018, at 2:58 PM, George Skorup > wrote: > > > > What suppressors? > > > >> On 6/9/2018 3:23 PM, Jason McKemie wrote: > >> I have a A5C that is giving me grief.

Surge suppressors can certainly cause this.

Re: [AFMUG] Mikrotik / Mimosa Ethernet Errors
The easiest way to tell is obviously to take the SS out and see if the errors stop. And as Chuck has said in the past, an SS can get wounded. Definitely seen that. In fact, just the other day I had two 450 sectors with link losses, falling back to 10Mbps, etc. and quite a lot of errors. Took the Rev D SS's out and the errors were gone. Replaced them with new Rev E's I happened to have in my truck and they're running fine (100Mbps and Canopy sync). The Rev D's did their job.

I think Chuck said the clamp voltage is around 90-100 volts. The cheap stuff might die, but it's cheap so who cares. On 6/9/2018 3:58 PM, George Skorup wrote: What suppressors?

They are Chuck's suppressors and I'm pretty sure they are an older revision as well, so that could be a contributing factor.
