Safety Instructions
Safety Instructions
Before You Begin
Before handling the product, read the instructions and safety guidelines on the
following pages to prevent damage to the product and to ensure your own personal
safety. Refer to the “Advisories” section in the Preface for advisory conventions used
in this user’s guide, including the distinction between Warnings, Cautions, Important
Notes, and Notes.
Always use caution when handling/operating a computer. Only qualified,
experienced, authorized electronics service personnel should access the
interior of a computer. The power supplies produce high voltages and
energy hazards, which can cause bodily harm.
Use extreme caution when installing or removing components. Refer to the
installation instructions in this user’s guide for precautions and procedures.
If you have any questions, please contact our Post-Sales Technical
Support.
WARNING
High voltages are present inside the chassis when the unit’s power cord is
plugged into an electrical outlet. Turn off system power, turn off the power
supply, and then disconnect the power cord from its source before
removing the chassis cover. Turning off the system power switch does not
remove power to components.
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1. Turn off the computer and any peripherals.
2. Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.

Safety Instructions
3. Follow the guidelines provided in “Preventing Electrostatic Discharge” on the
following page.
4. Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds after
turning off the computer before removing a component, removing a system
board, or disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop,
not on the cable itself. Some cables have a connector with locking tabs. If you
are disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly
aligned to avoid bending any connector pins. Also, before connecting a cable,
make sure both connectors are correctly oriented and aligned.
CAUTION
Do not attempt to service the system yourself except as explained in this
user’s guide. Follow installation and troubleshooting instructions closely.
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation
and follow proper ESD procedure to reduce the risk of damage to components. We
strongly encourage you to follow proper ESD procedure, which can include wrist
straps and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component’s antistatic packing material until you are ready to install
the component in a computer. Just before unwrapping the antistatic packaging,
be sure you are at an ESD workstation or grounded. This will discharge any
static electricity that may have built up in your body.
When transporting a sensitive component, first place it in an antistatic container

Safety Instructions
or packaging.
Handle all sensitive components at an ESD workstation. If possible, use
antistatic floor pads and workbench pads.
Handle components and boards with care. Don’t touch the components or
contacts on a board. Hold a board by its edges or by its metal mounting bracket.
Do not handle or store system boards near strong electrostatic, electromagnetic,
magnetic, or radioactive fields.

Preface

Regulatory Compliance Statements
This section provides the FCC compliance statement for Class A devices.
FCC Compliance Statement for Class A Devices
The product(s) described in this user’s guide 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 user’s guide, may cause harmful
interference to radio communications. Operation of this equipment in a residential
area (domestic environment) is likely to cause harmful interference, in which case
the user will be required to correct the interference (take adequate measures) at

Preface
their own expense.
Changes or modifications not expressly approved by us could void the user's
authority to operate the equipment.
NOTE
The assembler of a personal computer system may be required to test
the system and/or make necessary modifications if a system is found to
cause harmful interference or to be noncompliant with the appropriate
standards for its intended use.
Maintaining Your Computer
Environmental Factors
Temperature
The ambient temperature within an enclosure may be greater than room
ambient temperature. Installation in an enclosure should be such that the
amount of air flow required for safe operation is not compromised.
Consideration should be given to the maximum rated ambient temperature.
Overheating can cause a variety of problems, including premature aging and
failure of chips or mechanical failure of devices.
If the system has been exposed to abnormally cold temperatures, allow a
two-hour warm-up period to bring it up to normal operating temperature before
turning it on. Failure to do so may cause damage to internal components,
particularly the hard disk drive.
Humidity
High-humidity can cause moisture to enter and accumulate in the system. This
moisture can cause corrosion of internal components and degrade such
properties as electrical resistance and thermal conductivity. Extreme moisture
buildup inside the system can result in electrical shorts, which can cause
serious damage to the system.
Buildings in which climate is controlled usually maintain an acceptable level of
humidity for system equipment. However, if a system is located in an unusually
humid location, a dehumidifier can be used to maintain the humidity within an
acceptable range. Refer to the “Specifications” section of this user’s guide for

Preface
the operating and storage humidity specifications.
Altitude
Operating a system at a high altitude (low pressure) reduces the efficiency of
the cooling fans to cool the system. This can cause electrical problems related
to arcing and corona effects. This condition can also cause sealed components
with internal pressure, such as electrolytic capacitors, to fail or perform at
reduced efficiency.
Power Protection
The greatest threats to a system’s supply of power are power loss, power spikes,
and power surges caused by electrical storms, which interrupt system operation
and/or damage system components. To protect your system, always properly
ground power cables and one of the following devices.
Surge Protector
Surge protectors are available in a variety of types and usually provide a level
of protection proportional with the cost of the device. Surge protectors prevent
voltage spikes from entering a system through the AC power cord. Surge
protectors, however, do not offer protection against brownouts, which occur
when the voltage drops more than 20 percent below the normal AC line voltage
level.
Line Conditioner
Line conditioners go beyond the overvoltage protection of surge protectors.
Line conditioners keep a system’s AC power source voltage at a fairly constant
level and, therefore, can handle brownouts. Because of this added protection,
line conditioners cost more than surge protectors. However, line conditioners
cannot protect against a complete loss of power.
Uninterruptible Power Supply
Uninterruptible power supply (UPS) systems offer the most complete protection
against variations on power because they use battery power to keep the server
running when AC power is lost. The battery is charged by the AC power while it
is available, so when AC power is lost, the battery can provide power to the
system for a limited amount of time, depending on the UPS system.
UPS systems range in price from a few hundred dollars to several thousand
dollars, with the more expensive unit s allowing you to run larger systems for a

Preface
longer period of time when AC power is lost. UPS systems that provide only 5
minutes of battery power let you conduct an orderly shutdown of the system,
but are not intended to provide continued operation. Surge protectors should be
used with all UPS systems, and the UPS system should be Underwriters
Laboratories (UL) safety approved.

Overview
This chapter provides the definitions and locations of jumpers, headers, and
connectors.
Jumpers
The product has several jumpers which must be properly configured to ensure
correct operation.
Figure 3 Jumper Connector
For a three-pin jumper (see figure above), the jumper setting is designated “1-2”
when the jumper connects pins 1 and 2. The jumper setting is designated “2-3”
when pins 2 and 3 are connected and so on. You will see that one of the lines
surrounding a jumper pin is thick, which indicates pin No.1.
To move a jumper from one position to another, use needle-nose pliers or tweezers
to pull the pin cap off the pins and move it to the desired position.
