Thanks for the update!!

I think the PoE is slightly different on the new series 5 boards.

The new boards look enough different it may be worth trying on 48v next time we get a chance.

Some 532s have a problem with generating interference in that frequency range. IIRC its a 48v POE issue.

We have had a couple of instances of the same problem.

Try changing to an 18V power supply and re-jumpering the 532 for the lower voltage range.

Hi Normis, It would be great if we either had new MT hardware with more horsepower (preferred) or support for the xScale processors. We're getting behind the performance curve for single board computers unless we go to something like a Pentium M which is expensive and harder to power... A teaser sta...

Re: SR9 compatibility with RB112?

Will the SR9 card work in a RB112? I was thinking about getting a couple to setup a PtP link to do some testing but wasn't sure if the RB112 could provide the necessary power requirements for the card? Thanks Yes. Read this thread. Towards the bottom is quite a bit of data on a working SR9/RB112 li...

OK, please forgive me for pointing out the obvious. MT runs differently ion different platforms. We use VIA, Intel, AMD, RB230s, RB532s and RB112s. They all have their little quirks and oddities. It is no surprise that a card with known hardware glitches is going to run differently on different plat...
