Well, at last.  Something SGI I can _talk_ about, instead of _ask_ about.

On my Challenge L, the switch in the back (the circuit breaker) is funky.
It feels a bit limp when you move it; it doesn't have the firm internal
"snap" you'd expect.  If you just move it from "Off" to "On", it doesn't
really go on.  You have to snap it over fairly quickly and forcefully.  If
you do that when the machine's plugged in, the power-supply fans come on, no
matter the keyswitch position.  If the PS fans are on, and you'll hear 'em
if they are, the key switch will do something.  Otherwise it won't.
