Safety Precautions
Dell Compellent 33
 Donotworkalonewhenworkingwithhigh‐voltagecomponents.
 Donotusematsdesignedtodecreaseelectrostaticdischargeasprotectionfrom
electricalshock.Instead,userubbermatsthathavebeenspecificallydesignedas
electricalinsulators.
 DonotremovecoversfromthePowerControlModule(PCM).Disconnectthepower
connectionbeforeremovingaPCMfromtheenclosure.
 DonotremoveafaultyPCMunlessyouhaveareplacementmodelofthecorrecttype
readyforinsertion.AfaultyPCMmustbereplacedwithafullyoperationalmodule
within24hours.
 Permanentlyunplugtheenclosurebeforeyoumoveitorifyouthinkithasbecome
damagedinanyway.WhenpoweredbymultipleACsources,disconnectallsupply
powerforcompleteisolation.
General Safety Precautions
Toavoidinjuryanddamagetotheequipment,alwaysfollowgeneralsafetyprecautions.
 Keeptheareaaroundthechassiscleanandfreeofclutter.
 Placethe chassiscoverandanysystemcomponentsthathavebeenremovedawayfrom
thecontrolleroronatablesothattheyarenotinthewayoffoottraffic.
 Whileworkingonthecontroller,donotwearlooseclothingsuchasnecktiesand
unbuttonedshirtsleeves,whichcancomeintocontactwithelectricalcircuitsorbe
pulledintoacoolingfan.
 Removeanyjewelryormetalobjectsfromyourbodybecausetheyareexcellentmetal
conductorsthatcancreateshortcircuitsandharmyouiftheycomeintocontactwith
printedcircuitboardsorareaswherepowerispresent.
 DonotliftanenclosurebythehandlesofthePowerCoolingModules(PCMs).Theyare
notdesignedtoholdtheweightoftheentireenclosure,andtheenclosurecovermay
becomebent.
 Beforemovinganenclosure,removethePCMstominimizeweight.
 Inordertocomplywithapplicablesafety,emission,andthermalrequirements,donot
removebaycoversfromenclosures.Makesurethatallbaysarepopulatedwithplug‐in
modules.
 Donotremovebaycoversordrivesuntilreadytoreplacethem.
Warning: Disconnectpowerfromthecontrollerwhenremovingorinstalling
componentsthatarenothot‐swappable.Whendisconnectingpower,firstpower
downthecontrollerusingtheStorageCenterSystemManagerandthenunplugthe 
powercordsfromallthepowersupplymodulesinthecontroller.
Warning: Toavoidinjury,donotattempttotheliftacontrollerorenclosureby
yourself.Alwaysgetassistancewhenliftingthecontroller.
Caution: Donotoperatethecontrollerwithoutthecover,exceptwhenreplacing
coolingfans.
Warning: Thememorymodulesmaybehotforseveralminutesafterthecontroller
hasbeenpowereddown.Waitforthememorymodulestocoolbeforehandling
them.
