3.5 Timing Requirements
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 200mS. 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 needs to be greater 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
show 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.

3.6 Power Good Signal: PWOK
PSOK is a power OK signal and will be pulled HIGH by the power supply to indicate that
all the outputs are within the regulation limits of the power supply. When any output voltage
falls below regulation limits or when AC power has been removed for a time sufficiently
long so that power supply operation is no longer guaranteed, PWOK will be de-asserted to a
LOW state. See for a representation of the timing characteristics of PWOK. The start of
PWOK delay time shall inhibited as long as any power supply output is in current limit.

3.7 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 and -12V power rails. When this signal is not
pulled low by the system, or left open, the outputs (except the +5VSB and Vbias) turn off.
This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply.

external protectcard is not present), then all outputs shut down in a latch off mode. The latch
shall be cleared bytoggling the PSON# signal or by cycling the AC power. The power
supply shall not be damaged fromrepeated power cycling in this condition. If only one
module works inside the power supply, the OPP is at 110%~170% of rating of power supply.

supply should beshut down in a latch off mode while the respective output current exceeds
the limit as shown in Table 8.

6.2 Input Leakage Current
Input leakage current from line to ground will be less than 3.5mA rms. Measurement will be
made at 240 VAC and 60Hz.
6.3 Production Line Testing
100% of the power supply production must have the following test performed. Each power
shall be marked indicating the testing was done and passed. Typically this is done by
stamping or labeling the power supply with "Hi-pot test OK".
6.4 Hi-Pot Testing
Each power supply must be Hi-pot tested according UL and TUV requirements, Minimum
typical testing voltage for Hi-pot testing are 1500Vac or 2121Vdc. However depending on
the power supply design the testing voltage May be higher. If higher the power supplies
shell be at the higher value.
6.5 Ground Continuity Testing
UL and TUV require that each power supply ground is tested, to ensure there is continuity
between the ground inlet of the power supply and the power supply chassis. This can be
performed with an ohm meter, or an electronic circuit that lights up and illustrates the
ground has continuity. Based on EN50116, ERG or TUV require that each power supply
ground id tested with a 25Amp ground test.

7. Redundant Power Supply Function:
7.1 Redundancy
The redundant power supply is 1+1=1 (550W+550W=550W)
(460W+460W=460W) function power , 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.
7.2 Hot Swap Requirements
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:
X
AC connecting separately to 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.
X
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.
7.3 LED Indicators
There shell be a single bi-color LED or Two LEDs, one AMBER and one GREEN, on each
hot swap power module to indicate power supply status. When AC is applied to the power
supply and standby voltage are available the GREEN LED shall BLINK. The GREEN LED
shall turn ON to indicate that all the power outputs are available. The AMBER LED shall
turn ON to indicate that the power supply has failed, shutdown due to over current, or
shutdown due to component failure. The LED(s) shall be visible on the power supply's
exterior face. 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 it to become
displaced.
12
8. Reliability
8.1 Mean Time Between failures (MTBF)
The MTBF of the power supply shall be calculated utilizing the Part-Stress Analysis method
of Bellcore MIL217F. The calculated MTBF of the power supply shall be greater than
100,000 hours under the following conditions:
Full rated load, 120V AC input, Ground Benign, 25ᑻC
8.2 Warranty
Two (2) years manufacture's warranty.
Date code indicating the year (200X, X is the first code) and week (2, 3 Code is the week )
of manufacture.
Technical information in this specification is subject to change without notice.
The revision of specification will be marked on the cover.
