disconnect all power cables from the existing system before you add a device.
 Use one hand, when possible, to connect or disconnect signal cables to prevent a possible shock
from touching two surfaces with different electrical potentials.

About This Manual
1230B0026701 iv
 This product is equipped with a three-wire power cable and plug for user safety. Use the power
cable with a properly grounded electrical outlet to avoid electric shock.
Motherboards, adapters, and disk drives are sensitive to static electricity discharge. These devices are
wrapped in antistatic bags to prevent this damage. Take the following precautions:
 If you have an antistatic wrist strap available, use it while handling the device.
 Do not remove the device from the antistatic bag until you are ready to install the device in the
system unit.
 With the device still in its antistatic bag, touch it to a metal frame of the system.
 Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching the solder joints
or pins.
 If you need to lay the device down while it is out of the antistatic bag. Lay it on the antistatic bag.
Before picking it up again, touch the antistatic bag and the metal frame of the system unit at the
same time.
 Handle the devices carefully to prevent permanent damage.
Battery Replacement Safety
This server is provided with an internal Lithium battery or battery pack. There is a danger of explosion
and risk of personal injury if the battery is incorrectly replaced or mistreated.
For more information about battery replacement or proper disposal, contact an authorized reseller or your
authorized service provider.
This server contains an internal Lithium Manganese Dioxide, or a Vanadium Pentoxide, or an
alkaline battery pack. There is risk of fire and burns if the battery pack is not handled
properly. To reduce the risk of personal injury:
 Do not attempt to recharge the battery.
 Do not expose to temperatures higher than 70°C.
 Do not disassemble, crush, puncture, shorten external contacts, or dispose in fire or water
.
 Replace only with the spare parts designated for this product.
Batteries should not be littered along with the general household waste. Please use the public
collection system or return them to the supplier.

 Laser peripherals or devices have are not user serviceable.
 Return to manufacturer for servicing.
Intended Application 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, residential, alarm systems,
and test equipment), other than an ITE application, may require further evaluation.
Site Selection
The system is designed to operate in a typical office environment. Choose a site that is:
 Clean, dry, and free of airborne particles (other than normal room dust).
 Well-ventilated and away from sources of heat including direct sunlight and radiators.
 Away from sources of vibration or physical shock.
 Isolated from strong electromagnetic fields produced by electrical devices.
 In regions that are susceptible to electrical storms, we recommend you plug your system into a
surge suppresser and disconnect telecommunication lines to your modem during an electrical
storm.
 Provided with a properly grounded wall outlet.
 Provided with sufficient space to access the power supply cord(s), because they serve as the
product's main power.

Regulatory Compliance Identification Numbers
For the purpose of regulatory compliance certifications and identification, this motherboard is assigned a
serial number. This server serial number can be found on the product label, along with the required
approval markings and information. When requesting certification information for this product, always
refer to this serial number. This serial number should not be confused with the marketing name or model
number.
Product Regulatory Compliance
Product Safety Compliance
The motherboard complies with the following safety requirements:
IEC 60950-1 Safety of Information Technology Equipment
EN 60950-1 Safety of Information Technology Equipment Including Electrical Business
Equipment, European Committee for Electrotechnical Standardization
(CENELEC)
UL 60950-1 Safety of Information Technology Equipment

GB4943 Safety of Information Technology Equipment
Worldwide Safety approvals can be supplied according to the requirements from Marketing or Customer.
Product EMC Compliance
This product has been tested and verified to comply with the following electromagnetic compatibility
(EMC) regulations.
Communications Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many
electronic devices, including computers, generate RF energy incidental to their intended function and are,
therefore, covered by these rules. These rules place computers and related peripheral devices into two
classes, A and B, depending upon their intended installation. Class A devices are those that may
reasonably be expected to be installed in a business or commercial environment. Class B devices are
those that may reasonably be expected to be installed in a residential environment (for example, personal
computers). The FCC requires devices in both classes to bear a label indicating the interference potential
of the device as well as additional operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls into. Class A devices do

About This Manual
1230B0026701 vii
not have an FCC logo or FCC ID on the label. Class B devices have an FCC logo or FCC ID on the label.
Once the class of the device is determined, refer to the following corresponding statement.
Class A Equipment
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at personal expense.
Declaration of Conformity for Products Marked with the FCC Logo—United States Only
This device complies with Part 15 of the FCC Rules Operation and is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
For questions regarding your product, please contact the supplier.
To identify this product, refer to the Part, Series, or Model number found on the product.
European Union Notice
Products with the CE Marking comply with both the EMC Directive (89/336/EEC) and the Low-Voltage
Directive (73/23/EEC) issued by the Commission of the European Community.
Compliance with these directives implies conformity to the following European Norms (in brackets are
the equivalent international standards):
EN55022 (CISPR 22) Electromagnetic Interference
EN55024 (IEC61000-4-2,3,4,5,6,8,11) Electromagnetic Immunity
EN61000-3-2 (IEC61000-3-2) Power Line Harmonics
