2.4 Output Dynamic Loading
All outputs must maintain their regulation as per section 2.1 when loaded to the
following loading combination:
1. Maximum continuous combined load on +3.3V and +5V outputs shall not
exceed 150W.
2. The total output power can not exceed 2400W continuously. During load
changes from minimum to maximum or maximum to minimum the unit must
not shut down.
The following output ripple/noise requirements will be met throughout the load
ranges specified in Section 2.2 and under all input voltage conditions specified
in Section 2.1. Ripple and noise are defined as periodic or random signals over
the frequency band of 10Hz to 20MHz. Measurements will be made with an
oscilloscope set to 20MHz bandwidth limit. Measurement is done by using
10uF Tantalum in parallel with a 0.1uf ceramic capacitor, measured directly
at the output connector side.

The output voltages shall remain within the limits specified in 2.2 for the step
loading and within the limits specified
in 2.6 for the capacitive loading. The load transient repetition rate shall be
tested between 50Hz and 5kHz at duty
cycles ranging from 10%-90%. The load transient repetition rate is only a test
specification. The Δ step load may
occur anywhere within the MIN load to the MAX load shown in 2.5.

3.1 Timing Requirements
3. Controls and Signal
These are the timing requirements for the power supply operation. The output voltages must rise
from 10% to within regulation limits (Tvout_rise) within 10 to 70ms. The +3.3V, +5V and +12V
output voltages should start to rise at about the same time. All outputs must rise smoothness. The
+5V output needs to be greater than the +3.3V output during any point of the voltage rise. The +5
V output must never be greater than the +3.3V output by more than 2.25 V.
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 andFigure 2 the turn ON and turn OFF timing requirements. In Figure 2, the timing is
shown with both AC and PSON# controlling the ON/OFF of the power supply.

3.2 PS_ON
3.3 PWOK(Power OK)
Table 1: PSON# Signal Characteristic
PWOK Signal Characteristics
The PSON# signal is required to remotely turn on/off the power supply.
PSON# is an active low signal that turns on the +3.3V, +5V, +12V, and –12V
power rails. When this signal is not pulled low by the system,or left open, the
outputs (except the +5 VSB and Vbias) turn off. This signal is pulled to a
standby voltage by a pull-up resistor internal to the power supply.
PWOK 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.
For a representation of the timing characteristics of PWOK. The start of the
PWOK delay time shall be inhibited as long as any power supply output is in
current limit.

Protection Cicuits
3.4 Over Current Protection
Table 4: Over Current Protection
3.5 Over Voltage Protection
The power supply shall have current limit to prevent the +3.3V, +5V, and
+12V outputs from exceeding the values shown in Table 4. If the current limits
are exceeded, the power supply shall shutdown and latch off. The latch will be
cleared by toggling the PSON# signal or by an AC power interruption. The
power supply shall not be damaged from repeated power cycling in this
condition. –12 V and 5 VSB shall be protected under over current or shorted
conditions so that no damage can occur to the power supply. All outputs shall
be protected so that no damage occurs to the power supply under a shorted
output condition.
Note: When the rated output power of the installed module is lower than the
backplane output power, the module's OPP/OCP protection settings shall
take precedence.
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. Table 5 contains the over voltage limits. 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 pins 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 pins of the
Protection circuits inside the power supply shall cause only the power supply’s
main outputs to shutdown. If the power supply latches off due to a protection
circuit tripping, an AC cycle OFF for 10 seconds and a PSON# cycle HIGH for
1 second shall be able to reset the power supply.

4.Environmental Requirements
When the PS_ON button is pressed, the buzzer on the PDB will emit a short
"beep" sound, indicating that the power supply module has started normally.
When the backplane and both power modules are operating normally, any
input power module failure (SMBAlert low), or Power Good fault (PG low) will
trigger the buzzer alarm.
After the buzzer alarm is triggered, it helps users quickly locate the faulty
module by sound. If the fault is not removed while the system remains
powered, the buzzer will stay in alarm state untill the power supply fault is
cleared or the system power is turned off, after which the alarm will gradually
disappear. It the alarm noise causes disturbance in the working environment,
the user can press the mute switch on the back panel to forcibly stop the
buzzer alarm.
The LED blinks as an alert to help users locate the faulty unit through visual
observation.
The LED signal is derived from the PSU (SMBAlert). When either PSU1 or
PSU2 has a low-level (SMBAlert) signal,the LED will blink. When both PSUs
output a high-level signal, the LED remains steadily on.
