v Forredundant andhot-swappableoperation,thepowersuppliesareconnectedto 200-240Vac.
Working inside the server with the power on
Attention: Staticelectricity thatisreleased tointernalservercomponentswhen theserverispowered-onmightcausetheserverto halt,whichcouldresultinthe lossof data.Toavoidthispotentialproblem,alwaysuseanelectrostatic-discharge wriststrapor othergroundingsystem whenworkinginsidetheserverwiththe poweron.
Theserversupportshot-plug,hot-add,andhot-swapdevicesandisdesignedto operatesafelywhileit isturnedonandthecoverisremoved.Followthese guidelines whenyouworkinsidea serverthatisturnedon:
Handling static-sensitive devices
Attention: Staticelectricitycan damagetheserverandotherelectronicdevices.
Toavoiddamage,keep static-sensitivedevicesintheirstatic-protectivepackages until youarereadytoinstall them.
Toreducethepossibilityofdamagefromelectrostaticdischarge,observethe following precautions:
v Limityour movement.Movementcan causestaticelectricity tobuilduparound you.
v Theuseofa groundingsystemisrecommended.Forexample,wear an electrostatic-dischargewriststrap, ifoneisavailable.Always usean
electrostatic-dischargewriststrap orothergroundingsystem whenworkinginside theserverwiththepoweron.
v Handlethedevicecarefully,holdingit byitsedgesor itsframe.
v Donottouchsolderjoints,pins,orexposedcircuitry.
v Donotleavethedevice whereotherscanhandleanddamageit.
v Whilethedeviceisstillinitsstatic-protectivepackage,touchit toanunpainted metalpartontheoutsideoftheserverforat least2 seconds.Thisdrainsstatic electricityfromthepackageandfromyourbody.
v
Removethedevice fromitspackageandinstallit directlyintotheserverwithout settingdownthedevice. Ifit isnecessary tosetdownthedevice,putitbackinto itsstatic-protectivepackage.Donotplacethedeviceontheservercoverorona metalsurface.
v Takeadditional carewhenhandlingdevicesduringcold weather.Heatingreduces indoorhumidityandincreasesstaticelectricity.

Installing a hot-swap power supply
Thefollowingnotesdescribeinformationthatyoumustconsiderwheninstalling a hot-swappowersupplyintheserver:
v Theservercomeswithaminimumofonepowersupplyandsupports upto two powersupplies(hot-swappableat220Vaconly).
v Thepowersuppliesarenumberedfromleftto right(1and2)asviewedfromthe rearoftheserver.Powersuppliesmustbeinstalledinthefollowingsequence:
powersupply1,thenpowersupply2.
v Asingle110Vacpowersupply cansupportamaximumconfigurationofone microprocessor,twoPCI-Xadapters,threeharddiskdrives,andfourDIMMs.If youexceedthis configurationyoumust eitherinstalla secondpowersupplyor use220Vacinput.

4. If youarereplacingafailedpowersupply,removethefailedpowersupply from thebay:
a. Disconnectthepowercordfromtheconnectoronthebackof thefailed powersupply.
b. Press thelockinglatchonthepower-supplyhandleandraisethe power-supplyhandleto theopenposition.
c. Liftthefailedpowersupplyoutofthebay.
5. Raise thehandleonthenewpowersupplyto theopen position.
6. Place thenewpowersupplyintothepower-supplybayinthechassisandfully closethelockinghandle.
7. Connectoneendof thepowercordfor thenew powersupplyintotheconnector onthebackof thepowersupply; routethepowercord throughthe
