Turn On/Off Timing (Power Supply Signals) 13.2.6 Protection Circuits Protection circuits inside the power supply causes only the power supply's main outputs to shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15sec and a PSON# cycle HIGH for 1sec able to reset the power supply. 13.2.6.1 Current Limit (OCP) Below are over current protection limits for each output. If the current limits are exceeded the power supply shuts down and latch off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The power supply does not be damaged from repeated power cycling in this condition. -12V and 5VSB is protected under over current or shorted conditions so that no damage can occur to the power supply. 5Vsb will be auto-recovered after removing OCP limit.

The power supply shuts down and latch off after an over voltage condition occurs. This latch is cleared by toggling the PSON# Revision 1.2 139 Intel order number G26942-003
