SafetyPrecautions

Observethefollowingsafetyprecautionsbeforeperforminganyinstallationorbreak/fixproceduresinvolvingdisassemblyorreassembly:

Turnoffthesystemandanyattachedperipherals.

DisconnectthesystemandanyattachedperipheralsfromACpower,andthenremovethebattery.

Disconnectanytelephoneortelecommunicationslinesfromthesystem.

Useawristgroundingstrapandmatwhenworkinginsideanycomputersystemtoavoidelectrostaticdischarge(ESD)damage.

Afterremovinganysystemcomponent,carefullyplacetheremovedcomponentonanantistaticmat.

Wearshoeswithnonconductiverubbersolestohelpreducethechanceofbeingshockedorseriouslyinjuredinanelectricalaccident.

StandbyPower

Dellproductswithstandbypowermustbecompletelyunpluggedbeforeopeningthecase.Systemsthatincorporatestandbypowerareessentiallypoweredwhileturnedoff.

Theinternalpowerenablesthesystemtobesuspendedintoasleepmode,andhaveotheradvancedpowermanagementfeatures.Afterunpluggingthesystem,allowthe

chargetodrainfromthecircuitsbywaitingapproximately30to45secondsbeforeremovingcomponents.

ElectroStaticDischarge(ESD)Protection

ESDisamajorconcernwhenhandlingelectroniccomponents,especiallysensitivedevicessuchasexpansioncards,processors,memoryDIMMs,andsystemboards.Very

slightchargescandamagecircuitsinwaysthatmaynotbeobvious,suchasintermittentproblemsorashortenedproductlifespan.Astheindustrypushesforlowerpower

requirementsandincreaseddensity,ESDprotectionisanincreasingconcern.

DuetotheincreaseddensityofsemiconductorsusedinrecentDellproductsthesensitivitytostaticdamageisnowhigherthaninpreviousDellproducts,forthisreasonsome

previouslyapprovedmethodsofhandlingpartsarenolongerapplicable.

WARNING:

DonotuseanESDgroundingstrapwhenworkingontheinternalpartsofamonitor,liketheCRT,becausethestoredvoltageisextremelyharmful.

TherearetworecognizedtypesofESDdamage,"catastrophic"and"Intermittent"failures.

CatastrophicThedamagecausesanimmediateandcompletelossofdevicefunctionality.AnexampleofcatastrophicfailureisamemoryDIMwhichhasreceiveda

staticshockandimmediatelygeneratesa"NoPOST/NoVideo"symptomwithabeepcodeemittedforamissingornonfunctionalmemory.

NOTE:

Catastrophicfailuresonlyrepresentroughly20%ofESDrelatedfailures.

IntermittentTheDIMMreceivesastaticshock,butthetracingismerelyweakenedanddoesnotimmediatelyproduceoutwardsymptomsrelatedtothedamage.The

weakenedtracemighttakeweeksormonthstomelt,andinthemeantimemaycausedegradationofmemoryintegrity,intermittentmemoryerrors,etc.

NOTE:

Intermittentfailuresrepresentalmost80%ofESDrelatedfailures.Thismeansthatthemajorityofthetimewhenthedamageoccurs,itisnotimmediately

recognizable.

Ofthesetwotypes,themoredifficulttorecognizeandtroubleshootisthe"Intermittent"(alsocalledLatentor"walkingwounded")failure.Theimagebelowisanexampleofan

"Intermittent"damagetoamemoryDIMMtrace.Asyoucansee,thedamageisdonealthoughthesymptomsmaynotbecomeanissueorcausepermanentfailuresymptoms

forsometimeafterthedamageoccurs.

Intermittent(Latent)damagetoawiringtrace

Topreventstaticdamage,dothefollowing:

UseaWired(notwireless)ESDwriststrapthatisproperlygrounded.Theuseofwirelessantistaticstrapsinnolongerallowed,astheydonotgiveadequate

protection.

WiredESDStrap(Acceptable)

WirelessESDStrap(Unacceptable)

Furthermore,simplytouchingthechassisbeforehandlingpartsisnolongerallowedbecausethismethoddoesnotensureadequateESDprotectiononpartswith

increasedsensitivitytoESDdamage.

Chassis"Baremetal"Grounding(Unacceptable)

Handleallstaticsensitivecomponentsinastaticsafearea.Ifpossible,useantistaticfloorpadsandworkbenchpads.

Whenhandlingstaticsensitivecomponents,grabthembythesides,notthetop.Avoidtouchingpinsandcircuitboards.

Whenunpackingastaticsensitivecomponentfromitsshippingcarton,donotremovethecomponentfromtheantistaticpackingmaterialuntilyouarereadytoinstall

thecomponent.Beforeunwrappingtheantistaticpackaging,besuretodischargestaticelectricityfromyourbody.

Beforetransportingastaticsensitivecomponent,placeitinanantistaticcontainerorpackaging.

InsulatorElements

ItiscriticaltokeepESDsensitivedevicesawayfrominternalpartswhichareinsulatorsandareoftenhighlycharged.Theseareelementssuchasplasticheatsinkcasings.

TransportingSensitiveComponents

WhentransportingESDsensitivecomponentssuchasreplacementpartsorpartstobereturnedtoDell,itiscriticaltoplacethesepartsinantistaticbagsforsafetransport.

ESDProtectionSummary

Itisstronglysuggestedthatallfieldserviceengineersusethetraditional"wired"ESDgroundingwriststrapandprotectiveantistaticmatatalltimeswhenservicingDell
