Intel server boards contain a number of high-density VLSI and power delivery components that need adequate airflow for
cooling. Intel’s own chassis are designed and tested to meet the intended thermal requirements of these components when
the fully integrated system is used together. It is the responsibility of the system integrator that chooses not to use Intel
developed server building blocks to consult vendor datasheets and operating parameters to determine the amount of airflow
required for their specific application and environmental conditions. Intel Corporation can not be held responsible if
components fail or the server board does not operate correctly when used outside any of their published operating or nonoperating limits.

Safety Information
WARNING
Although you may be using this guide or another resource as a
reference, before working with your server product pay close attention
to the safety instructions. You must adhere to the assembly
instructions in this guide to ensure and maintain compliance with
existing product certifications and approvals. Use only the described,
regulated components specified in this guide. Use of other products /
components will void the UL listing and other regulatory approvals of
the product and will most likely result in noncompliance with product
regulations in the region(s) in which the product is sold.
WARNING
All LAN ports of the equipment are considered Type 2 or Type 4 intrabuilding ports as described in NEBS GR-1089-CORE, Issue 4. The
LAN ports are suitable for connection to intra-building or unexposed
wiring or cabling only. The LAN ports of the equipment MUST NOT
be metalically connected to interfaces that connect to the OSP or its

Preface
Emissions Disclaimer
To ensure EMC (Electromagnetic Compatibility) compliance with your local regional rules
and regulations, the final configuration of your end system product may require additional
EMC compliance testing. For more information, please contact your local Intel
Representative.
See “
Regulatory and Integration Information” for product Safety and EMC regulatory
compliance information. This is an FCC (Federal Communications Commission) Class A
device.
Intended Uses
This product was evaluated as Information Technology Equipment (ITE), which may be
installed in Central Offices, Telecommunication Centers, offices, schools, computer
rooms, and similar commercial type locations where the National Electrical Code (NEC)
applies. The suitability of this product for other product categories and environments
(medical, industrial, OSP telecommunications, residential, alarm systems, test equipment,
etc.), other than an ITE application, may require further evaluation.
WARNING
Anchor the equipment rack: The equipment rack must be anchored to
an unmovable support to prevent it from falling over when one or
more servers are extended in front of the rack on slides. You must
also consider the weight of any other device installed in the rack. A
crush hazard exists should the rack tilt forward which could cause
serious injury.
If AC power supplies are installed:
Mains AC power disconnect: The AC power cord(s) is considered the
mains disconnect for the server and must be readily accessible when
installed. If the individual server power cord(s) will not be readily
accessible for disconnection then you are responsible for installing an
AC power disconnect for the entire rack unit. This main disconnect
must be readily accessible, and it must be labeled as controlling
power to the entire rack, not just to the server(s).
Grounding the rack installation: To avoid the potential for an electrical
shock hazard, you must include a third wire safety ground conductor
with the rack installation. If the server power cord is plugged into an
AC outlet that is part of the rack, then you must provide proper
grounding for the rack itself. If the server power cord is plugged into a
wall AC outlet, the safety ground conductor in the power cord provides
proper grounding only for the server. You must provide additional,
proper grounding for the rack and other devices installed in it.

Preface
Overcurrent protection: The server is designed for an AC line voltage
source with up to 20 amperes of overcurrent protection per cord feed.
If the power system for the equipment rack is installed on a branch
circuit with more than 20 amperes of protection, you must provide
supplemental protection for the server. The overall current rating of a
configured server is less than 6 amperes. It is intended that an
external Surge Protective Device (SPD) will be utilized at the AC
power service for the equipment.
If DC power supplies are installed:
Connection with a DC (Direct Current) source should only be
performed by trained service personnel. The server with DC input is to
be installed in a Restricted Access Location in accordance with
articles 110-16, 110-17, and 110-18 of the National Electric Code,
ANSI/NFPA 70. The DC source must be electrically isolated by double
or reinforced insulation from any hazardous AC source. The DC
source must be capable of providing up to 600 Watts of continuous
power per feed pair.
Main DC power disconnect: You are responsible for installing a
properly rated DC power disconnect for the server system. This mains
disconnect must be readily accessible, and it must be labeled as
controlling power to the server. The circuit breaker of a centralized DC
power system may be used as a disconnect device when easily
accessible and should be rated no more than 10 amps.
Grounding the server: To avoid the potential for an electrical shock
hazard, you must reliably connect an earth grounding conductor to the
server. The earth grounding conductor must be a minimum 14AWG
connected to the earth ground stud(s) on the rear of the server. The
safety ground conductor should be connected to the chassis stud with
a Listed closed two-hole crimp terminal having 5/8 inch pitch. The
nuts on the chassis earth ground studs should be installed with a
10 in/lbs torque. The safety ground conductor provides proper
grounding only for the server. You must provide additional, proper
grounding for the rack and other devices installed in it. The battery
return input terminal is designed as an isolated DC return (DC-I) from
the frame earth ground per NEBS GR-1089-CORE.
Overcurrent protection: Overcurrent protection circuit breakers must
be provided as part of each host equipment rack and must be
incorporated in the field wiring between the DC source and the server.
The branch circuit protection shall be rated minimum 75Vdc, 10 A
maximum per feed pair. If the DC power system for the equipment
rack is installed with more than 10 amperes of protection, you must
provide supplemental protection for the server. The overall current
rating of a server configured is 10 amperes.

System Cooling
All system components except the power supply cage are cooled by a set of fans mounted
near the middle of the chassis and behind the hard drive bays. The TIGI2U system comes
in a non-redundant, four-fan configuration that consists of two 80mm x 38mm fans and two
40mm x 28mm fans.
Air flows in through the front bezel over the peripheral bay and the hard drive bays,
passes through the fans and over the baseboard, and exhausts through the rear of the
chassis. Each fan provides tachometer signal output to the server baseboard to indicate a
fan failure.
The cooling subsystem contains a fan array consisting of two 80 x 38 mm fans and two 40
x 28 mm fans to cool the server board and other components. A fan failure is indicated by
one of the fault LEDs located on the front panel.
Hardware Requirements
To avoid integration difficulties and possible board damage, your system must meet the
requirements outlined below. For a list of qualified components, see the links under
“
Additional Information and Software.”

Memory
The Server Board SE7520JR2 provides six DIMM sockets across two channels, Channel
A and Channel B. Channel A consists of DIMM sockets 1A, 2A, and 3A. Channel B
consists of DIMM sockets 1B, 2B, and 3B.
If six DIMMs are installed, the following maximum capacitites are possible:
For DDR-2 400: Maximum capacity of 16 GB
A minimum of one 256MB DIMM is required in DIMM socket 1A or 1B. This uses singlechannel interleave. However, for dual-channel interleave, providing optimum performance,
a minimum of two DIMMs should be installed in DIMM sockets 1A and 1B. Except for the
option of installing a single DIMM in socket 1A or 1B, DIMMs must be installed in pairs and
populated as follows:
DIMM1A and DIMM 1B: Populate these two sockets together first
DIMM 2A and DIMM 2B: Populate these sockets in addition to DIMM 1A and DIMM 2A
if four DIMMs are to be used.
DIMM 3A and DIMM3B: Populate these sockets after DIMM 1A, DIMM1B, DIMM2A,
and DIMM2B have been populated.
DIMMs must meet the following requirements:
Use only DDR2-400 ECC, registered DDR DIMM modules
Use only DIMMs that comply with the DDR specifications.
Use only DIMMs with DIMM organization of x72 ECC
Use only 240pin DIMMs
NOTE
When using DDR2-400 DIMM technologies, a maximum of four loads per memory channel
is supported. When all DIMMs used in the system match this technology, a maximum of
four DIMMs can be populated. Refer to the IntelProduct Specification for additional information regarding the memory sub-system.
In determining your memory requirements, the need for memory sparing or memory
mirroring must be considered.
Memory Sparing and Mirroring
The Intel® E7520 chipset includes hardware that supports memory mirroring and memory
on-line sparing. Both memory mirroring and memory on-line sparing provide a way to
prevent data loss in case a DIMM fails.
With memory mirroring the system maintains two copies of all data in the memory
subsystem. If a DIMM fails, the data is not lost because the second copy of the data is
available from the mirrored DIMM in the opposite channel. The system will not fail due to
memory error unless both the primary and the mirrored copy of the data become corrupt at
the same time.

with a minimum of four DIMMs installed. Since the data is duplicated across DIMMs, it
means that up to one-half of the installed DIMMs are actively in use at any one time. The
remaining DIMMs are used for mirroring.
Two methods for memory mirroring are available:
Four identical DIMMs are used in DIMM sockets 1A, 1B, 2A, and 2B.
⎯ If the DIMM in socket 1A fails, the DIMM in socket 2B takes over.
⎯ If the DIMM in socket 1B fails, the DIMM in socket 2A takes over.
Four DIMMs are used with identical single-ranked DIMMs in Banks 2 and 3. DIMMs in
sockets 1A and 1B must be dual-ranked and identical.
⎯ If the DIMM in socket 1A fails, the DIMM in socket 1B takes over.
⎯ If the DIMM in socket 2A fails, the DIMM in socket 3B takes over.
⎯ If the DIMM in socket 2B fails the DIMM in socket 3A takes over.
For memory on-line sparing, one DIMM per channel is used as the memory spare. The spare
DIMM is not available for use, but is kept in reserve. If a DIMM begins to fail, the content of the
failing DIMM is copied to the spare DIMM in that channel. When all of the data is copied to the
spare DIMM, the primary DIMM is removed from service and the spare DIMM takes its place.
When memory on-line sparing is used, the spare DIMMs must be equal to or larger than the
largest in-service DIMM in that channel.
NOTE
Memory mirroring and memory sparing are mutually exclusive. Only
one can be active at a time. Refer to the IntelSE7520JR2 Technical Product Specification for additional information
regarding the memory sub-system.
All memory components and DIMMs used with the Intel
must comply with the DDR specifications. For a complete list of supported memory
DIMMs, see the links under “
Additional Information and Software.”
