turning offthe computer before removing a component,removing a system
board,or disconnecting a peripheral device from the computer.
When you disconnecta cable,pull on its connectoror on its strain-relief loop,
noton 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 anyconnector pins.Also,before connecting a cable,
make sure both connectors are correctlyoriented and aligned.
CAUTION

remove the component’s antistatic packingmaterialuntil you are readyto install
the componentin a computer.Justbefore unwrapping the antistatic packaging,
be sure you are atan ESD workstation or grounded.This will discharge any
static electricitythatmayhave builtup in your body.
When transporting asensitive component, first placeitin an antistatic container
or packaging.
Handle all sensitive components at an ESD workstation.Ifpossible,use
antistatic floorpads and workbench pads.
Handle components and boards with care.Don’t touch the components or
contacts on aboard.Hold a board byits edges or byits metalmounting bracket.
Do nothandle orstoresystem boards nearstrong electrostatic, electromagnetic,
magnetic,or radioactive fields.

Maintaining Your Computer
EnvironmentalFactors
Temperature
The ambienttemperature within an enclosuremaybe greater than room
ambienttemperature.Installation in an enclosure should besuch thatthe
amountofair flow required for safe operation is notcompromised.
Considerationshould be given to the maximum rated ambienttemperature.
Overheating can cause a varietyof problems, including premature aging and
failure ofchips or mechanical failure ofdevices.
Ifthe system has been exposed to abnormallycold temperatures, allow a
two-hour warm-up period to bring it up to normal operating temperature before
turning iton.Failure to dosomaycause damage to internal components,
particularlythe hard disk drive.
Humidity
High-humiditycan cause moisture to enter and accumulate in thesystem.This
moisture can cause corrosion ofinternal components and degradesuch
properties as electrical resistance and thermal conductivity.Extrememoisture
buildup inside the system can resultin electrical shorts,which can cause
serious damage to the system.
Buildings in which climate is controlled usuallymaintain an acceptable level of
humidityfor system equipment.However,ifa system is located in an unusually
humid location,a dehumidifiercan be used to maintain the humiditywithin an
acceptable range.Refer to the “Specifications”section ofthis user’s guide for

the operating and storage humidityspecifications.
Altitude
Operating asystem ata high altitude (low pressure) reduces the efficiencyof
the cooling fans to cool thesystem.This can cause electrical problems related
to arcing and corona effects.This condition can also causesealed components
with internal pressure, such as electrolytic capacitors,to fail or perform at
reduced efficiency.
Power Protection
The greatestthreats to a system’s supplyofpower are power loss,power spikes,
and powersurges caused byelectricalstorms,which interruptsystem operation
and/or damagesystem components.To protectyour system,always properly
ground power cables and one ofthe following devices.
Surge Protector
Surge protectors are available in a varietyof types and usuallyprovide a level
ofprotection proportional with the costofthe device. Surge protectors prevent
voltage spikes from entering asystem through theAC power cord.Surge
protectors,however,do not offer protection againstbrownouts,which occur
when the voltage drops more than 20 percentbelow the normalAC line voltage
level.
Line Conditioner
Line conditioners go beyond the overvoltage protection ofsurge protectors.
Line conditioners keep asystem’s AC power source voltage ata fairlyconstant
level and,therefore,can handle brownouts.Because of this added protection,
line conditioners costmore than surge protectors.However,line conditioners
cannotprotectagainsta complete loss ofpower.
Uninterruptible Power Supply
Uninterruptible powersupply(UPS) systems offer the mostcomplete protection
against variations on power because theyuse batterypower to keep the server
running whenAC power is lost.The batteryis charged bythe AC power while it
is available,so whenAC power is lost,the batterycan provide power to the
system for a limited amountoftime,depending on the UPS system.
UPS systems range in price from a few hundred dollars to several thousand
dollars,with the more expensive units allowing you to run largersystems for a
