Intel® Server System SR2500AL 0BProduct Overview

1. Product Overview

The Intel® Server Chassis SR2500 is a 2U server chassis that is designed to support the Intel®
Server Board S5000PAL. The server board and the chassis have features that are designed to
support the high-density server market. This chapter provides a high-level overview of the
chassis features. Greater detail for each major chassis component or feature is provided in the
following chapters.

The chassis differs from previous generation products in that the majority of cables have been
removed from the system and in their place are a series of board-to-board interconnects. The
benefits of using board-to-board interconnects are simplification of platform integration and
improved airflow for more reliable cooling.

A second significant change from the previous generation is the introduction of the mid-plane
circuit board. There are two options for the mid-plane circuit board: the first option provides
SAS RAID support. The second option is a passive SATA/SAS mid-plane that can be used with
either the SATA only connectors from the server board, or SATA/SAS connectors from an add­in card.

1.8 System Cooling

The chassis is offered with two system cooling options. The first option is a three fan solution
providing sufficient airflow to maintain internal system thermal requirements when the external
ambient temperature remains within specified limits. The second option is a 5+1 fan
configuration. Refer to section 3.2 for details. Should a single fan failure occur, this option
provides support for hot-swap fans and fan redundancy.

In addition to the system fan options, each power supply module installed provides two
additional non-redundant fans which pull air from inside the chassis out the back.

2. Power Sub-System

The power sub-system of the chassis consists of an integrated Power Distribution Module
(PDM), a power module enclosure, and support for up to two 750 Watt power supply modules.
The power sub-system can be configured to support a single module in a 1+0 non-redundant
configuration, or dual modules in a 1+1 redundant power configuration. In a 1+1 configuration, a
single failed power module can be hot-swapped with the system running. Either configuration
will support up to a maximum of 750 Watts of power.

This chapter provides technical details to the operation of the power supply module and power
sub-system.

2.2 Single Power Supply Module Population

In single power module configurations, server management firmware requires that the power
supply module be populated in the top power module slot. The non-operating slot must have
the power supply blank installed.

AF000023

Figure 14. Power Supply Blank

Configuring a single power supply module in the bottom location will cause the server
management firmware and BIOS to generate a system error during POST and the error will be
reported to the System Event Log (SEL).

2.3 Handle and Retention Mechanism

Each power supply module includes a handle for module insertion to or removal from the
module enclosure. Each module has a simple retention mechanism to hold the power module
in place once it is inserted. This mechanism will withstand the specified platform mechanical
shock and vibration requirements. The tab on the retention mechanism is colored green

to
indicate it is a hot-swap touch point. The latch mechanism is designed to prevent insertion or
removal of the module with the power cord plugged in. This will aid the hot-swapping procedure.

2.4 Hot-swap Support

Hot-swapping a power supply module is the process of extracting and re-inserting a power
supply module from an operating power system. During this process the output voltages shall
remain within specified limits. Up to two power supply modules may be on a single AC line.
The power supply module can be hot-swapped by the method listed below.

Extraction: on removal, the power cord is unplugged first, and then the power module is
removed. This can be done in standby mode or power-on mode.

Insertion: The module is inserted first, and then the power cord is plugged in. If powered off, the
system and the power supply will power on into standby mode or power-on mode.

2.5 Airflow

Each power supply module incorporates two non-redundant 40mm fans for self cooling and
partial system cooling. The fans will provide no less than 10 CFM airflow through the power
supply when installed in the system and operating at maximum fan speed. The cooling air will
enter the power module from the PDB side (pre-heated air from the system).

2.6 AC Power Cord Specification Requirements

The AC power cord used must meet the following specification requirements:

Cable Type SJT
Wire Size 16 AWG

2.8.3 AC Line Dropout / Holdup

An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout of one cycle or less the power supply must
meet dynamic voltage regulation requirements over the rated load. If the AC dropout lasts
longer than one cycle the power supply should recover and meet all turn-on requirements. The
power supply must meet the AC dropout requirement over rated AC voltages, frequencies, and
output loading conditions. Any dropout of the AC line shall not cause damage to the power
supply.

20ms Min when tested under the following conditions: Max combined load = 525W,
12ms Min when tested under the following conditions: Max combined load = 750W

2.8.4 AC Line 5 VSB Holdup

The 5VSB output voltage should stay in regulation under its full load (static or dynamic) during
an AC dropout of 70ms min (=5VSB holdup time) whether the power supply is in ON or OFF
state (PSON asserted or de-asserted).

2.8.5 AC Inrush

AC line inrush current shall not exceed 40A peak for up to one-quarter of the AC cycle, after
which, the input current should be no more than the specified maximum input current. The peak
inrush current shall be less than the ratings of its critical components (including input fuse, bulk
rectifiers, and surge limiting device).

The power supply must meet the inrush requirements for any rated AC voltage, during turn on at
any phase of AC voltage, during a single cycle AC dropout condition as well as upon recovery
after AC dropout of any duration, and over the specified temperature range (T

). It is

op

acceptable that AC line inrush current may reach up to 60A peak for up to 1 msec.

2.9 Protection Circuits

Protection circuits inside the PDB and the power supply shall cause the power supply’s main
+12V output to shut down, or shall cause a shut down of any of the three outputs on the PDB.
Either of these shutdowns will result in shutting down the entire power supply / PDB
combination. If the power supply latches off due to a protection circuit tripping, an AC cycle
OFF for 15 seconds shall be able to reset the power supply and the PDB.

2.9.1 Over-Current Protection (OCP)

Each DC/DC converter output on the PDB shall have individual OCP protection circuits. The
power supply and power distribution board (PS and PDB) shall shutdown and latch off after an
over-current condition occurs. This latch shall be cleared by an AC power interruption. The
following table provides the over-current limits. The values are measured at the PDB harness
connectors. The DC/DC converters shall not be damaged from repeated power cycling in this
condition. The +12V output from the power supply is divided on the PDB into four channels
and each is limited to 240VA of power. There shall be current sensors and limit circuits to shut
down the entire PS and PDB if the limit is exceeded. The limits are listed below.

2.9.2 Over-Voltage Protection (OVP)

Each DC/DC converter output on the PDB shall have individual OVP circuits built in and they
shall be locally sensed. The PS and PDB shall shutdown and latch off after an over-voltage
condition occurs. This latch shall be cleared by an AC power interruption. The following table
provides the over-voltage limits. The values are measured at the PDB harness connectors. The
voltage shall never exceed the maximum levels when measured at the power pins of the output
harness 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 PDB connector.

2.9.3 Over-Temperature Protection (OTP)

The power supply will be protected against over-temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition the power supply will shutdown.
When the power supply temperature drops to within specified limits, the power supply shall
restore power automatically, while the 5 Vsb remains constantly on. The OTP trip level shall
have a minimum of 4°C of ambient temperature hysteresis, so that the power supply will not
oscillate on and off due to a temperature recovery condition. The power supply shall alert the
system of the OTP condition via the power supply FAIL signal and the PWR LED.

2.10.1 Output Power / Currents

The following table defines power and current ratings for this 750W continuous (860W pk)
power supply in 1+0 or 1+1 redundant configuration. The combined output power of both
outputs shall not exceed the rated output power. The power supply must meet both static and
dynamic voltage regulation requirements for the minimum loading conditions. Also, the power
supply shall be able to supply the listed peak currents and power for a minimum of 10 seconds.
Outputs are not required to be peak loaded simultaneously.
