1.6 Power Sub-System
The power sub-system consists of one non-redundant 400-watt power supply. It provides
integrated management features, including over-temperature protection circuitry and over-
voltage protection circuitry.
The power supply operates within the following voltage ranges and ratings:
Parameter Minimum Rated Maximum Start up VAC Power Off VAC
Voltage (110) 90 Vrms 100-127 Vrms 140 Vrms 85Vac +/-4Vac 75Vac +/-5Vac
Voltage (220) 180 Vrms 200-240 Vrms 264 Vrms
Frequency 47 Hz 63 Hz
The power supply must operate within all specified limits over the input voltage ranges shown in
the table. Harmonic distortion of up to 10% THD must not cause the power supply to exceed the
specified limits.
The power supply shall power off if the AC input is less than 75 VAC +/- 5 VAC range. The
power supply shall start up if the AC input is greater than 85 VAC +/- 4 VAC. Application of an
input voltage below 85 VAC shall not cause damage to the power supply, including a fuse blow.
1.7 System Cooling
The system provides two non-redundant blower fans. The Intel®Server System
SR1530CL/SR1530CLR (SATA) also includes an additional PCI cooling fan. When external
ambient temperatures remain within specified limits, the cooling system will provide sufficient air
flow for all drive configurations, processors, supported memory, and add-in cards.
1.8 Rack and Cabinet Mounting Options
The Intel®Server System SR1530CL/SR1530CLR (SATA) can be installed in 19-inch wide by
up to 30-inch deep server cabinets. The system supports three rack mount options:
A fixed mount relay rack/cabinet mount kit which can be configured to mount the system
into either a 2-post or 4-post rack cabinet. (Product order code for the cabinet mount kit:
AXXBRACKETS).
A tool-less full extracting slide rail kit designed to support an optional cable management
arm. (Product order code for the sliding rail kit: AXXHERAIL. Product order code for the
cable management arm: AXXRACKCARM).
A basic slide rail kit designed to mount the chassis into a standard 19-inch by up to 30-
inch deep EIA-310D compatible server cabinet. (Product order code for the slide rail kit:
AXXBASICRAIL).

2. Power Sub-System
This specification defines a 400-watt non-redundant power supply that supports a 1U rack
mount server system. The power supply and the power supply sub-system shall have five
outputs; 3.3 V, 5 V, 12 V, -12 V, and 5 VSB. The input shall be auto-ranging and power factor
corrected. The form factor is SSI EPS1U at 300 mm depth and wire harness output.
The power supply provides two non-redundant 40 mm fans for self-cooling. The power supply
fans also contribute to the airflow for parts of the system.

2.3 Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels; 100%, 50% and 20%. Efficiency shall be
tested over an AC input voltage range of 115 VAC to 220 VAC.

2.4 AC Input Voltage Requirement
The power supply must operate within all specified limits over the following input voltage range,
shown in below table. Harmonic distortion of up to 10% THD must not cause the power supply
to go out of specified limits. The power supply shall power off if the AC input is less than 75
VAC +/- 5 VAC range. The power supply shall start up if the AC input is greater than 85 VAC +/-

4 VAC. Application of an input voltage below 85 VAC shall not cause damage to the power
supply, including a fuse blow.

2.5 Protection Circuits
Protection circuits inside the power supply shall cause only the power supply’s main outputs to
shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle off for
15 seconds and a PSON#cycle high for 1 second shall be able to reset the power supply.
2.5.1 Over-current Protection (OCP)
The power supply shall have current limit to prevent the +3.3 V, +5 V, and +12 V outputs from
exceeding the values shown in the following table. 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. Auto-recovery feature is a requirement on 5
VSB rail.

+3.3V 110% minimum (= 16.5A) ; 150% maximum (= 22.5A)
+5V 110% min (= 11.0A); 150% max (= 15.0A)
+12V 39.6A min; 54.0A max
-12V 0.625A min; 2.0A max
5VSB 6.0A max
2.5.2 Over-voltage Protection (OVP)
The power supply over-voltage protection shall be locally sensed. The power supply shall shut
down 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 following table 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 power supply connector.
Exception: +5VSB rail should be able to recover after an over-voltage condition occurs.
