[widar-wg] CPCC Battleshort Fixture

[Brent Carlson]

Kevin,

I think it would be better to have a cold standby, fully loaded and tested
CPCC c/w NI6509 boards, which gets powered up and tested say, when the
smoke tests are done, on a regular basis.  If you do what you suggest,
then there is no remote control, and everything is up or down at the same
time.  It could be a bit more sophisticated, and have some basic rack
power sequencing, but that is a complete PCB design (I think it is
anyway).  Better and probably cheaper in the long run to have the cold
standby, IMHO.
