Short Circuit Protection (OCP)
A short between ground and any group 1 output will shutdown all of group 1.
A short between ground and group 2 will shutdown both group 1 and group 2.
(Group 1 is everything but the +5VSB rail and Group 2 is the +5VSB. Short the +5VSB rail and the complete power supply is shut down, short any of the other rails and the +5VSB remains live.)
Reset After Shutdown
Whenever the power supply latches into the shutdown state due to a fault condition on any output, the power supply will return to normal operation only after the fault has been removed and the power switch cycled off/on with a minimum off time of 20mS.
