[c-nsp] Problem w/ ASR1001

[Mack McBride]

Intermittent low power (brown out) can give very odd behavior.
An on-line/inline UPS would filter these out while an off-line/standby UPS may not catch the issues.
Due to slight differences in the actual ratings of the various components (+-10% usual on capacitors)
one device may have issues while another does not.  This may not be the case
but it is at least worth investigating.

No, they are on a two separate circuits provided by the housing which both are UPS/generator buffered (separate modules, too). As I said though, the second 1001 is also on the same circuits, so it ought to display at least similar problems ...
Also, if it's a general problem on the feed, shouldn't all output voltages have the problems at the same time, and not on one output voltage for some time, while all the others are fine, then on a different for a while, with again all other voltages OK?

Weird ...

Tnx, -garry
