Connecting Power to the Switch
Youcanconnecttoasingleprimarysourceofpowerortotwosourcesofpowerforredundancy,as
describedinthefollowingsections.Theexampleusedheredescribesconnectingtwopower
sources.
ThefollowingredundantpowersuppliesareavailabletobepurchasedfromEnterasysfor
connectiontotheD2switch.
Followtheappropriateinstructionsinthissectiontoinstallyour
component(s):
•D2‐PWR,aDCpowersupplycapableofprovidingpowertoafully‐loadednon‐PoEswitch.

ToconnectpowertotheD2switch:
1. Ifyouhavenotalready
donesoaspartofoneoftheswitchmountingprocedures,plugtheDC
endofthepowercordfromeachpowersupplyintoeachoftheswitchDCpowerreceptacles
thatareappropriateforyourtypeofpowersupplies.
•FortheD2‐PWRsupply,plugintothePWR1‐Aand
PWR2‐Areceptacles
•FortheD2‐PWR‐POEsupply,plugintothePWR1‐BandPWR2‐Breceptacles
•FortheD2‐HIPWR‐POEpowercombiner,attachcablingasinstructedin“Connectinga
D2‐HIPWR‐POEPowerCombiner”onpage 2‐25.
2. PlugtheACcordintothepowersupply’sACreceptacle.Repeat
foreachpowersupply.
3. PlugeachACpowercordintoadedicated,groundedACoutlet.
4. VerifythattheappropriatepowerLEDs(PWR1andPWR2)turnonasdescribedinTable 2‐1
onpage 2‐27andtheCPU(system)LEDturnsreduntiltheD2completesitsinitialization.
TheseLEDsarevisiblefrom

Notes: Both power supplies must be of the same type to support redundancy.
The D2-PWR supply will power either the D2G124-12 or the D2G124-12P without PoE support. The
D2-PWR-POE is the only supply for powering the D2G124-12P with PoE support
Note: To take advantage of redundancy capabilities, each power cord must be plugged into a
separate, dedicated AC outlet.
Note: It is normal for the surface of the device to be warm.
