Can you expand on what a "12v slot AC cycle" means?  I can't decipher

Vijay was working on a complete power cycle of the entire server, as if
it were unplugged and plugged back in.  This was done as a different
object (chassis_system0) from the object representing the host (chassis0).

The chassis0 typically models the power rails that drive the host
processor.  The power cycle of those is already the primary feature of
x86-power-control.  Can you expand on what the differences are with the
system you're working on?
