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 non-operating limits.

Safety Information
WARNING
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.
Emissions Disclaimer
To ensure EMC 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 the “Regulatory and Integration Information” for product safety compliance and EMC
regulatory compliance information. This is an FCC Class A device. Integration of it into a Class B
chassis does not result in a Class B device.
Intended Uses
This product was evaluated as Information Technology Equipment (ITE), which may be installed in
offices, schools, computer rooms, and similar commercial type locations. The suitability of this
product for other product categories and environments (such as: medical, industrial,
telecommunications, NEBS, residential, alarm systems, test equipment, etc.), other than an ITE
application, may require further evaluation
EMC Testing
Before computer integration, make sure that the chassis, power supply, and other modules have
passed EMC testing using a server board with a microprocessor from the same family (or higher)
and operating at the same (or higher) speed as the microprocessor used on this server board.
WARNING
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

Preface Intel® Entry Server Board SE7221BK1-E User Guide
vi
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 (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.
