Intel workstation 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 workstation board does not operate correctly when used outside any of their published operating or
non-operating limits.

Warnings
iv Intel® Workstation Board S5520SC Service Guide
Warnings
Heed safety instructions: Before working with your server product, whether you are
using this guide or any other resource as a reference, 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.
System power on/off: The power button DOES NOT turn off the system AC power.
To remove power from system, you must unplug the AC power cord from the wall
outlet. Make sure the AC power cord is unplugged before you open the chassis, add
or remove any components.
Hazardous conditions, devices, and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the server and
disconnect the power cord, telecommunications systems, networks, and modems
attached to the server before opening it.Otherwise, personal injury or equipment
damage can result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives,
boards, and other parts. We recommend that you perform all procedures in this
chapter only at an ESD workstation. If one is not available, provide some ESD
protection by wearing an antistatic wrist strap attached to chassis ground⎯any
unpainted metal surface⎯on your server when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to ESD. Hold boards only by their edges. After removing a board from its
protective wrapper or from the server, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the
board wrapper. Do not slide board over any surface.
Installing or removing jumpers: A jumper is a small plastic encased conductor that
slips over two jumper pins. Some jumpers have a small tab on top that you can grip
with your fingertips or with a pair of fine needle nosed pliers. If your jumpers do not
have such a tab, take care when using needle nosed pliers to remove or install a
jumper; grip the narrow sides of the jumper with the pliers, never the wide sides.
Gripping the wide sides can damage the contacts inside the jumper, causing
intermittent problems with the function controlled by that jumper. Take care to grip
with, but not squeeze, the pliers or other tool you use to remove a jumper, or you may
bend or break the pins on the board.

The Intel®Workstation Board S5520SC provides an embedded SATA controller that supports both 1.5 Gbps
and 3.0 Gbps data transfer rates.
The BIOS Setup Utility provides drive configuration options on the Advanced | Mass Storage Controller
Configuration setup page, some of which affect the ability to configure RAID. The “On-board SATA Controller”
option is enabled by default and when enabled, you can set the “SATA Mode” option to one of the following
four modes:
“Enhanced” – Enhanced Mode supports up to six SATA ports with IDE native Mode.
“Compatibility” – Supports up to four SATA ports [0/1/2/3] with IDE Legacy mode and two SATA ports
[4/5] with IDE Native Mode.
“AHCI” – Supports all SATA ports using the Advanced Host Controller Interface.
“SW RAID” – Intel®Embedded Server RAID Technology II is enabled by “SW RAID” mode. The Intel®
Embedded Server RAID Technology II feature provides RAID modes 0, 1, and 10.
If RAID 5 is needed, you must install the optional Intel®RAID Activation Key AXXRAKSW5 accessory. This
activation key is placed on the SATA_ RAID_5_Key connector located on the left side of the workstation board.
For installation instructions, see the documentation included with the activation key.

When Intel®Embedded Server RAID Technology II is enabled with embedded SATA controller, enclosure
management is provided through the SATA_SGPIO connector on the workstation board when a cable is
attached between this connector and the backplane or I2C interface.

Hardware Requirements
To avoid integration difficulties and possible board damage, your system must meet the following requirements
outlined. For a list of qualified components, see the links under “Additional Information and Software”.
Processor
One or two Intel®Xeon®Processor 5500 series or Intel®Xeon®Processor 5600 series
For a list of supported processors, see the links under “Additional Information and Software”.
You must populate the processors in sequential order. You must populate processor socket 1 (CPU 1) before
processor socket 2 (CPU 2).
For optimum performance when two processors are installed, both must be the identical revision and have the
same core voltage and Intel®QPI/Core speed.
Memory
The Intel®Workstation Boards provides twelve DIMM sockets in six channels. Each channel contains two
DIMM sockets:
Channel A contains DIMM sockets A1 and A2
Channel B contains DIMM sockets B1 and B2
Channel C contains DIMM sockets C1 and C2
Channel D contains DIMM sockets D1 and D2
Channel E contains DIMM sockets E1 and E2
Channel F contains DIMM sockets F1 and F2

Figure 6. DIMM Sockets
DDR3 DIMMs must meet the following requirements:
Use only 240-pin DDR3 DIMMs.
A minimum of one 1 GB DDR3 DIMM is required in DIMM socket DIMM_A1.
Either registered DDR3 DIMMs (RDIMMs) or ECC unbuffered DDR3 DIMMs (UDIMMs). No mixing of
RDIMMs and UDIMMs.
Mixing memory type, size, speed, and/or rank on this platform has not been validated and is not
supported
Mixing memory vendors is not supported on this platform by Intel
Non-ECC memory is not supported and has not been validated in a server environment
DDR3-800, DDR3-1066, or DDR3-1333
DIMM within a channel must be populated starting with the first socket (blue socket) of the channel:
DIMM_A1, DIMM_B1, DIMM_C1, DIMM_D1, DIMM_E1, or DIMM_F1.
