Unpacking a Power Supply
TheK‐AC‐PS‐1400WpowersupplymodulesareshippedinboxesseparatefromtheK‐Series
chassis.Tounpackapowersupply:
1. Unpackthepowersupplybyremovingitfromtheshippingboxandslidingthetwofoamend
capsofftheunit.
Savetheshippingboxandmaterialsin
theeventtheunitmustbereshipped.
2. Verifythecontents oftheboxusingTable 3‐2asappropriate.
3. Removethepowersupplyfromitsprotectiveplasticbag.
4. Examinethepowersupplycarefully,checkingfordamage.
Ifanydamageisnoted,DONOTinstallthepowersupply.ContactEnterasysNetworks

Installing a Power Supply
YoumustinstallatleastoneK‐AC‐PS‐1400WpowersupplyintheK6chassis.Dependingonyour
moduleconfiguration,onepowersupplymayprovidesufficientpowertothechassis,but
multiplepowersuppliescanbeinstalledtoprovidearedundant,loadsha ringpowersource.
WhenyoureceiveyourK6
chassis,acoverplatewillbeinplaceoverpowersupplyslotsPS2,PS3,
andPS4.
ThepowersuppliesmustbeinstalledintheslotslabeledPS1,PS2,PS3,andPS4atthebottomof
thechassis.Ifyouintendtoinstallasinglepowersupply,youmustinstallitin
thepowersupply

ToinstalltheK‐AC‐PS‐1400Wpowersupplies:
1. Attachtheanti‐staticwriststrapasdescribedin“AttachingtheElectrostaticDischargeWrist
Strap”onpage 3‐12beforehandlingthepowersupply.
