Over Temperature Protection (OTP)
The power supply will be protected against over temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition the PS module will shutdown.
When the power supply temperature drops to within specified limits, the power supply shall
restore power automatically, while the 5VSB remains always on. The OTP trop level shall have
a minimum of 4 C of ambient temperature hysteresis, so the power supply will not oscillate on
