Re: [AFMUG] Brown-outs, Power fluctuations lock up Mikrotik CRS units

If the voltage is dipping low enough, the power supply may not be able to provide enough current to provide the necessary power at that low a voltage, resulting in a brief power deficiency.

They appear powered and running, but SFP+ modules don't communicate until a power cycle. Anyone else see this? And generally, I don't understand how variations in 110v AC get through the DC power wart and cause problems to the CRS. I mean, shouldn't the conversion from AC to DC inherently clean up some of the crap of the AC power? Or is this a function of the power dipping low enough for brief time, that the DC also goes almost out then surges back? The CRS handles a wide range of DC input voltage, so I thought it would be more immune to fluctuations of DC voltage too. Is that what is causing problems with the CRS maybe?
