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 Quanmax Post-Sales Technical
Support.
„ Access can only be gained by service persons or by users who have
been instructed about the reasons for the restrictions applied to the
location and about any precautions that shall be taken; and access is
through the use of a tool or lock and key, or other means of security,
and is controlled by authority responsible for the location.
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.
Follow the guidelines provided in “Preventing Electrostatic Discharge” on the
following page.
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.
Quanmax strongly encourages 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
or packaging.
„ Handle all sensitive components at an ESD workstation. If possible, use
antistatic floor pads and workbench pads.

Preface
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
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.
KUBE-8050/8051 User’s Manual
12
Preface
„
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
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.

RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
