[Rack] minotaur is down

well, the payphone is one physical serial port, and the upstairs keypad is 
another.  These are important because they are actual RS232 lines running 
long distances (like in the 1970's) and they are pretty mission-critical 
(literally in the mission) and the extra USB-serial layer would suck for 
that.  so i'm glad we don't need to do that.

it used to be that there were serial ports out to each net appliance, for 
remote management.  I think that can be done over USB serial adaptor just 
fine, and if we need more i know where they are hiding.

you will notice a four-way plug that has yellow and black wires, and goes 
to the blue serial cables.  Those are 12v power for the payphone and 
upstairs keypad.  On minotaur there was a jack on the motherboard that 
happened to put out 12v like that, so that's what that is.  If you find a 
way to power those from the new situation that would be great.

i hope that the minotaur downtime doesn't get confused with the new door 
access policy.
