Okay, it's just that I was testing the switch position just to see what it
did, and everything went off including the front panel. I guess it's
supposed to do that.
I don't know why DEC didn't put a standby LED on the front - you'd think
because it's already powering the MOS, you wouldn't care about powering some
silly LED.
What does that position do if core is installed?

It's been a long time I had the switch at the Standby position.
*IIRC*, everything goes OFF, and only MOS memory is powered,
but there are a few wires on the backplane, where the power
leads are soldered, that connect the backup supply pins to
the main supply pins. To use the memory battery backup, you
must remove these wires, but without a battery and the
charger plus a cable to the BA11 power supply, it is useless.

I just have a question about Standby mode on an 11/34. I read it's
supposed to leave power applied to MOS, but do the fans and whatnot
turn off along with the CPU? Or are they supposed to stay on? My
junk's in a BA11-K box.
