| Subject: | Out of pocket for a few days |
I'm running low on books. My printer is in Denver
and we usually pick up orders with a 15 hour
day-trip.
This time we're leaving a couple days early to
spend some time communing with those big piles
of rock around Salida, Estes Park, etc before
returning via Denver.
Not taking a computer with me this trip so
I'll be off-line until Saturday. Hold down
the fort guys!

Agreed.
Note that Z101 uses only ONE switch to control
an second power path to specific busses. NORMAL
power is carried through a diode from the main
bus. I.e. if the main bus is up, all busses
are up.
Otherwise, reduced energy operation protocols
are managed with closure of one switch per bus.
Essentially zero probability for un-manageable loss of
power to any bus.
