the PDB harness connectors. The voltage must never exceed the maximum levels when
measured at the power pins of the output harness connector during any single point of fail. The
voltage must never trip any lower than the minimum levels when measured at the power pins of
the
PDB connector.

4.7.3
Over-temperature Protection (OTP)
The power supply must be protected against over temperature conditions caused by loss of
forced air-cooling or excessive ambient temperature. In an over-temperature condition the PS
will shutdown. The Standby output may also shutdown or remain powered on. When the power
supply temperature drops to within specified limits, the power supply must restore power
automatically. The OTP circuit must have built in hysteresis such that the power supply will not
oscillate on and off due to temperature recovering condition. The power supply must alert the
system of the OTP condition through the power supply.

PMBus*
The PMBus* features included in this specification are requirements for ac/dc silver box power
supply for use in server systems. This specification is based on the PMBus* Specifications Parts
I and II, revision 1.1X3.

Addressing
The power supply device address locations are shown below. For redundant systems, there are
two signals to set the address location of the power supply once it is installed in the system;
Address0 and Address1. For non-redundant, systems the power supply device address
locations should align with the Address0/Address1 location of 0/0.
