Introduction
Thiswhitepaperdescribesrecommendedcableroutingprocedures,bothwithandwithouttheoptionalCable
ManagementArm(CMA)fortheDell™PowerEdge™R710inthefollowingracks:
•PowerEdge4210
•PowerEdge2410
•PowerEdge4220
•PowerEdge2420
IfusingtheoptionalCMA,followingtheseprocedureswillallowyoutoextendthesystemfromtherackforservice
withoutpoweringdownordisconnectingthecables.IfnotusingtheCMA,followingtheseprocedureswillensure
secureattachmentandstrainreliefofthecablesbehindthesystem.Forguidelinesonhowtoroutecableswithin
therack,refertotheDellWhitePaper“BestPracticesGuideforRackEnclosures.”
CablingaPowerEdgeR710withCMA
ThissectiondetailshowtocableaPowerEdgeR710usingaCMA.Ifyouarecablingthesystemwithoutthe
optionalCMA,pleasereferto“CablingaPowerEdgeR710WithoutaCMA”laterinthiswhitepaper.
FollowtheinstructionscontainedintheRackInstallationGuidefoundintherailkittoinstalltheserverintothe
rackandtoinstallthecables.AllillustrationsinthefollowingsectionswerecreatedusingaPowerEdgeR710.
NOTE:ThePowerEdgeR710isnotcompatiblewithprevious‐generationrailsandCMAs.
2.1InstallingtheCablestotheSystem
AttachtheCMAtraytothebackoftherailsasdescribedintheCMAInstallationInstructionsprovidedintheCMA
kit.Pluginallapplicablecablestotherearofthesystem.Verifythatallconnectionsaresecure.SeeFigure1.

2.2RoutethePowerCablesThroughtheStrainReliefs
Afterthetrayandcablesareinstalled,routethepowercablesthroughthestrainreliefslocatedonthepower
supplyhandlesasshowninFigure2.

2.3RoutingtheCablesThroughtheCMA
NOTE:TheCMAcanbeinstalledoneithertherightorleftrearsideoftherails.MountingtheCMAontheside
oppositethepowersupplies(leftsidemount)isrecommended;otherwise,theCMAmustbedisconnectedinorder
toremovetheouterpowersupply.Referto“ReplacingaPowerSupplyonaPowerEdgeR710withCMA”laterin
thiswhitepaperfordetailsonpowersupplyreplacement.
NOTE:Forguidelinesonhowtoroutecableswithintherack,refertotheDellWhitePaper“BestPracticesGuide
forRackEnclosure”.
LeftSideMountingInstructions
1. InstalltheCMAontheleftrearsideoftherailsbyattachingbothCMAhousingstotheattachmentbracketson
therails.SeeFigure3.
2. RoutethecablesthroughtheCMAwhilekeepinganytwistingofthecablestoaminimum.Ifthecablebundle
includesaKVMdongle,placethedongleinsidetheCMAbasket.UsethehookandloopstrapsontheCMAto
securethecables.

3. OnceallthecablesareroutedthroughtheCMA,dressthecablesbetweenthebackofthesystemandthe
entranceoftheCMAwiththetiewrapsprovidedintheCMAkit.Thetiewrapsareshowninyellowinall
illustrations.
4. Clipofftheexcesslengthofmaterialfromthetiewrapsandmakesurethatthetiewrapsarepositionedto
avoidinterferencewithadjacentsystems.
5. ReturntheCMAtotheclosed(retracted)position.
6. Extendthesystemfromtheracktoverifythereissufficientslackinthecablesatboththeentranceandexitof
theCMA.
7. SeeFigure4foranexampleofacompletedleftsidemountedCMAinstallation.
Cables entering CMA should
have a small amount of slack
to avoid cable strain when
CMA is extended.
NOTE: Do not store excess
cable slack inside the CMA.
The cable may protrude
through the CMA causing
binding and potentially
damaging the cable.

NOTE:TheCMAontheDellPowerEdgeR710isoptional.WithouttheCMAinstalled,thesystemmustbepowered
downandallcablesdisconnectedbeforeitcanberemovedfromtherack.
3.1RoutingtheCables
1. Pluginallapplicablecablestotherearofthesystem,verifyingthatallconnectionsaresecure.

2. Usingthehookandloopstrapssuppliedwiththerailkit,bundlethecablesandsecurethemtoeithertheleft
railorrightrailCMAattachmentbracketsasdescribedintheRackInstallationGuide.SeeFigure6foran
exampleofpowercablessecuredtotherightCMAbracketanddatacablessecuredtotheleftCMAbracket.
3. Itisrecommendedthatthecablesbesecuredtotheouterbrackets,butcablesmaybesecuredtotheinner
bracketsifdesired.

ReplacingaPowerSupplyonaPowerEdgeR710withCMA
1. RemovethetrayfromundertheCMAasdescribedintheCMAInstallationInstructionsprovidedwiththeCMA
kit.
2. SwingtheCMAintotheserviceposition.
3. Disconnectthepowercordfromthepowersupplyanddisengagethestrainrelief.
4. Removeandreplacethepowersupply
a. IftheCMAisattachedtotherightsideandtheouterpowersupplyneedstobereplaced,theinner
CMAattachmenthousingwillneedtobedisconnected.WhilesupportingtheCMAwithonehand,
removeandreplacethepowersupplywiththeotherhandasshowninFigure7.
b. IftheCMAisattachedtotherightsideandtheinnerpowersupplyneedstobereplaced,theCMA
doesnotneedtobedisconnected.
c. IftheCMAisattachedtotheleftside,bothpowersuppliescanberemovedwithoutdisconnecting
theCMA.
5. Pluginthepowercord.
6. Re‐engagethestrainrelief.
7. ReplacetheCMAsupporttray.
