3.6.15.2 Over-voltage Protection (OVP)
The power supply over voltage protection shall be locally sensed. The power supply shall shutdown and latch
off after an over voltage condition occurs. This latch shall be cleared by toggling the PSON
#
signal or by an
AC power interruption. The values are measured at the output of the power supply’s connectors. The voltage
shall never exceed the maximum levels when measured at the power connectors of the power supply
connector during any single point of fail. The voltage shall never trip any lower than the minimum levels when
measured at the power connector. 12VSB will be auto-recovered after removing OVP limit.

3.6.15.3 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 PSU will shutdown. When the power supply
temperature drops to within specified limits, the power supply shall restore power automatically, while the
12VSB remains always on. The OTP circuit must have built in margin such that the power supply will not
oscillate on and off due to temperature recovering condition. The OTP trip level shall have a minimum of 4°C
of ambient temperature margin.
3.7 DC Power Supply Input Specifications
The following sections provide the DC Input Specifications for systems configured with DC power supply
modules.
NOTE: Product Safety Regulations pertaining to the use of DC power supplies require that chassis grounding
studs be used for all DC power supply configurations. In the event that chassis grounding studs are not
available on a given server chassis, systems must be configured with two DC power supplies, with each
connected to separate ground wires while the system is operational.
