Introduction 8
Redundant Power SupplyModules
The Switch is equippedwith asingle DES-7011RPS unit. Up tothreepowersupplyunits canbe
installedon the switch chassis. As networkmodulesare addedto thechassis, RPS units can be
addedfor betterloadbalancingandincreasedRPS lifespan.TwoRPS units must be usedfor full
loading operationofthe Switch. Refer to thepower consumption per module data in thetable below.
DES-7011 RPS Unit
§ One plus twopower module design (one pre-installed)
§ Each RPS unit supports up to 730 Watts (see power consumption information below)
§ Current sharing/ load balancing design
§ Full redundant featuredesign toensure continuous operation
§ Hot-swappable
§ Power management functions enabled
Use this table to calculate total power consumptionfor the Switch chassis. Do notexceed the 730Watt
maximumfor each RPS unit. For best load balancingperformance and RPS lifespanit is
recommended toallowfor redundancy.Two RPS unitsmust be usedfor full loadingoperationofthe
Switch, for these installations, an additional third RPS unitis also recommended for redundancy.
Unit/Module Total Power Consumption
Fan Tray Module 105 Watts (max.) per unit
DES-7003 64 Watts (max.) per unit

Remove asingle switch module followingtheprocedure listedbelow. Onlyone module should be
removed at atime. Wait for the process to be completed before removing (or inserting) another
module. Wear an ESD wrist strap to prevent damage to the module frompossible static electric
discharge.
To performa hot swap removal ofa switch module followthese steps:
1. Gentlydepress the Hot Swap button on thefront panel ofthe module youwant to remove.
The Hot Swap button is located betweenthePer Port LinkLED indicators and thePower and
Hot Swap Status indicators. The button can be pressed usingyour finger, a ballpointpen or
other suitableinstrument.
2. Observe the Hot Swap & Card Status LED indicator on theswitch module being removed. It
should blinkamber. During this phase the moduleis sending amessage to themaster (CPU)
module thata removal has beeninitiated.
3. The master module detectsthe removal and updates its database. The master module cuts
power to the switchmodulebeing removed. The Power LED indicator and all other LED
indicators on the switch module will go dark.
4. When you see that the switch module has been powered off you mayremove it. Unscrewthe
installation screws andpull both ejector levers toward the center ofthe front panel ofthe
module to unseatit fromthe backplaneofthe Switch.
5. Ifthe module is not being reinserted, completelyremove it fromthe slot. It should slideout
easilyin the guides. Be sure to properlystore the module.
6. If you do not intend to install another module in thevacant slot, cover it with one ofthe slot
faceplates includedwith the original shipment.
Note
Whenperforminga hot swap of aMasterCPU modulethe
procedure is essentially the same asa hot swapofother switch
modules.Theprocedureforremoving a PrimaryMaster CPU

Hot Swap Insertion of a Switch Module
Followtheprocedure listedbelowtoinsert anewswitch module into anavailableslot while theSwitch
is poweredon.Onlyonemodule should be insertedatatime. Wait for the process to be completed
before inserting or removing another module. Wear an ESD wrist strapto prevent damage to the
module frompossible staticelectric discharge.
1. Ifthe slot is covered with a faceplate,remove and save it for later use.
2. Carefullyremove the module fromits packaging.
3. Line upthemodule with thegrooved slot guides and insert it into the chassis. It should glide
easilytowardthebackofthe chassis. Push itin until the module ejector levers arein contact
with the chassis. Be careful not to bend the circuit board ofthe module. Modules for the DES-
7000should be oriented sothe model number ofthe module is at the top and the LED
indicators are on the bottom.
4. Push the ejector levers toward the center ofthemodule until theytouchthe front ofthe module.
This will push the bus connectors intobackplane ofthechassis.
5. Observe the Hot Swap & Card Status LED indicator on theswitch module. This will blink
amber for about 13 seconds after being inserted.During this time the CPU is recognizingthe
newswitch module and theswitch module is booting. A steadyamber light indicates a system
failure.
6. A steadygreen HotSwap & CardStatus LED indicator on the switch module indicates the
module is readyand running normally.The master (CPU) module recognizes the newswitch
module.
7. Hand-tighten the installation screws ateach end ofthemodule. The module is nowfirmly
seated in the chassis and powered on. This completes the hot swap insertion.

Hot SwapProcedure for Fan TrayModule
CAUTION
The Fan TrayModule canbe replacedwiththepoweron. If you
cannotreplacethefan tray immediately(withintwo minutes) the
Switchchassisshouldbe poweredoffto avoiddamage from
overheatingbeforethefantray isremoved.
Changingthefan traymodule for theDES-7000 andDES-7100 is asimple procedure however ifyou
choose to dothis while theSwitch is poweredon, besure to have thereplacement fan trayreadyat
hand sotheprocedure canbe completed as quicklyaspossible. It is not necessaryto initiate the hot
swapprocedure, theMasterCPUwill beaware offan trayremovalandinsertion.Removal ofthefan
traywill trigger the systemalert buzzer andthe FanFail LED indicator. Be sure to use proper ESD
groundingproceduresto avoid electrostatic discharge.The procedure belowdescribes this procedure
and changes to the LED indicators that occur.
WARNING
The fans will continue rotatingforseveral secondsafterpower to
theunitiscutoff.Use onlythehandle onthefrontofthefantray
when removing the device to avoidrisk of injury.
Inserting the fan trayinto the DES-7100 chassis
To change the fan tray:
1. Unscrewthe installation screws on each side ofthe module and pull the module fromout of
the chassis. Be careful not to dropthefan traywhen removing it.
2. Replace the fan traymodule immediatelyifthe Switch is powered on; insert the newunit using
the guides built into the chassis. It should glide easilyinto position ifit is properlylined up.
3. Push the moduletoward the backplane ofthe chassis until the front ofthemoduleis flush with
the front panel ofthe chassis. Youwill need to applyfirm pressure for about the last half
centimeter to establish thecontacts and firmlypositionthe unit in the backplane.
4. The fan traywill power on and be recognizedbythe Master CPU.You should seethe Hot
Swap& Card Status LED indicator on theMaster CPU module blinkfor about 13seconds
