2.3 Input power factor correction (Active PFC)
The power factor at 50% load shall be 0.9 at 230V input voltage.
2.4 Input current harmonics
When the power supply is operated in 90-264 VAC of Sec. 2.1, the input harmonic current drawn on the power line shall not exceed the limits set by IEC61000-3-2 Class A and GB17625.1 standards. The power supply shall incorporate universal power input with active power factor correction.
2.5 Dropout
An AC line dropout of 17mS or less shall not cause any tripping of control signals or protection circuits. If the AC dropout lasts longer than 17mS, the power supply should recover and meet all turn on requirements. The power supply shall meet the regulation requirement over all rated AC voltages, frequencies, and output loading conditions. Any dropout of the AC line shall not cause damage to the power supply. An AC line dropout is defined as a drop in AC line to 0 VAC at any phase of the AC line for any length of time.
3.1 Output current / loading
3.2 DC voltage regulation, ripple and noise
The following table defines power and current rating. The power supply shall meet both static and dynamic voltage regulation requirements for minimum load condition.
The power supply output voltages must stay within the following voltage limits when operating at steady state and dynamic loading conditions. All outputs are measured with reference to the return remote sense (Returns) signal. The +5V, +3.3V, +12V, -12V and +5VSB outputs are measure at the power supply connectors references to Returns. The +5V and +3.3V is measured at its remote sense signal (+5VS, +3.3VS) located at the signal connector.

These are the timing requirements for the power assembly operation. The output voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V output voltages should start to rise at about the same time. All outputs must rise monotonically. The +5V output must occur first than the +3.3V output during any point of the voltage rise. The +5V output must never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach regulation within 50 ms (Tvout_on) of each other during turn on of the power supply. Each output voltage shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1 and figure 2 shows the turn on and turn off timing requirement. In Figure 2, the timing is shown with both AC and PSON# controlling the on/off of the power supply.
Ripple and Noise shall be measured using the following methods: a) Measurements made differentially to eliminate common-mode noise. b) Ground lead length of oscilloscope probe shall be 0.25 inch. c) Measurements made where the cable connectors attach to the load. d) Outputs bypassed at the point of measurement with a parallel combination of 10uF tantalum capacitor in parallel with a 0.1uF ceramic capacitors. e) Oscilloscope bandwidth of 0 Hz to 20MHz. f) Measurements measured at locations where remote sense wires are connected. g) Regulation tolerance shall include temperature change, warm up drift and dynamic load.

3.4 Remote On/Off Control: PSON#
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +5V, +3.3V, +12V,-5V and –12V power rails. When this signal is not pulled low by the system, or left open, the outputs (except the +5VSB and V bias) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply.

The redundant power supply is N+1=N (500W+500W=500W) function power supply, each one module is redundancy when any one module was failed. To be redundant each item must be in the hot swap power supply module.
There is a single bi-color LED to indicate the power supply status. The Green LED turn ON to indicate that all the power outputs are available. The Orange LED (Green+Red) turn ON to indicate that the power supply has stand-by or failed shutdown due to over current, the Red LED turn ON to indicate the Fan of the power supply has failed. The LED(s) shall be visible on the exterior face of the power supply. The LED location shall meet ESD requirements. LED shall be securely mounted in such a way that incidental pressure on the LED shall not cause displaced.
7.1 Redundancy
The redundant power supply modules shall be hot swappable. Hot swapping a power supply is the process of inserting and extracting a power supply from an operating. During this process the output voltage shall remain within the limits specified in Table 7 with the capacitive load specified Table 9. The Sub-system shall not exceed the maximum inrush current as specified in section 2.2. The power supply can be hot swapped by the following methods: AC connects with each module. Up to two power supplies may be on a single AC power source. Extraction: The AC power will be disconnected from the power supply first and then the power supply is extracted from the sub-system. This could occur in standby mode or powered on mode. Insertion: The module is inserted into the cage and then AC power will be connected to the power supply module. For power modules with AC docking at the same time as DC. Extraction: The module is extracted from the cage and both AC and DC disconnect at the same Time. This could occur in standby or power on mode. No damage or arcing shall occur to the DC or AC contacts which could cause damage. Insertion: The AC and DC connect at the same time as the module is inserted into the cage. No damage to the connector contacts shall occur. The module may power on or come up into standby mode. Many variations of the above are possible. Supplies need to be compatible with these different variations depending upon the sub-system construction. In general, a failed (off by internal latch or external control) supply may be removed, then replaced with a good power supply (must use the same model); however, hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply may get turned on by inserting the supply into the system or by system management recognizing an inserted supply and explicitly turning it on.

8.1 PMBus communication
The PMBus serial bus communication devices for I2C data in the power supply shall be compatible with both SMBus 2.0 “high power” and I2C Vdd based power and drive. This bus shall operate at 3.3V but tolerant of 5V signaling. The SMBus pull-ups are located on the motherboard and may be connected to 3.3V or 5V. Two pins are allocated on the power supply. One pin is the serial clock (SMBus_SCL). The second pin is used for serial data (SMBus_SDA). Both pins are bi-directional and are used to form a serial bus. The device(s) in the power supply shall be located at an address(s) determined by addressing pins A0 and A1 on the power supply module. The circuits inside the power supply shall derive their power from the 5VSB bus. Device(s) shall be powered from the system side of the 5VSB device. No pull-up resistors shall be on SCL or SDA inside the power supply. There pull-up resistors should be located external to the power supply.
8.2 Power supply management interface
The device in the power supply shall derive its power off of the 5VSB output on the system side. It shall be located at an address set by the A0 and A1 pins. Refer to the PMBus specification posted on the www.powerSIG.org website for details on the power supply monitoring interface requirements. I2C is a SMBus interface used to communicate power management information to the system.
