Introduction
Thiswhitepaperdescribesrecommendedcableroutingprocedures,bothwithandwithouttheoptionalCable
ManagementArm(CMA)fortheDell™PowerEdge™R610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Enclosure.”
CablingaPowerEdgeR610withCMA
ThissectiondetailshowtocableaPowerEdgeR610usingaCMA.Ifyouarecablingthesystemwithoutthe
optionalCMA,pleasereferto“CablingaPowerEdgeR610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R610.
NOTE:ThePowerEdgeR610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and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R610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Enclosures”.
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.Usethehookand
loopstrapsontheCMAtosecurethecables.

3. IfthecablebundleincludesaKVMdongle,placethedongleinsidetheCMAbasket.IftheKVMdonglewillnot
fitinsidethebasketwiththeothercables,attachthedongletotheexteriorofthefrontbasketusingthehook
andloopstrapsontheCMAbasketasshowninFigure4.

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.

4. 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.
5. 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.
6. ReturntheCMAtotheclosed(retracted)position.
7. Extendthesystemfromtheracktoverifythereissufficientslackinthecablesatboththeentranceandexitof
theCMA.

CablingaPowerEdgeR610withoutaCMA
NOTE:TheCMAontheDellPowerEdgeR610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7foran
exampleofpowercablessecuredtotheleftCMAbracketanddatacablessecuredtotheright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.

3.1 RemovingtheCMABracketsforShallowRacks
Ifyouareinstallingthesystemintoashallowrack(lessthan1mdeep)andyouwillnotbeinstallingaCMA,the
outerCMAbracketsmayberemoved,enablingtherailstofitintotherack.RemovetheouterCMAbracketsby
removingbothscrewswitha#2PhilipsscrewdriverasshowninFigure8.
