Thefollowingredundantpowersuppliesareavailableforpurchase
fromEnterasysNetworksforconnectiontoanA2switch:
•C2RPS‐PSM,a150wattDCpowersupplycapableofproviding
power
toafully‐loadednon‐PoEswitch.
•C2RPS‐POE(A2H124‐24PandA2H124‐48Ponly),500wattDC
powersupplyforPoEswitches.
Topower‐upyourA2switch:
1. Ifyouareconnectingaredundantpowersupply,attachthe
C2RPS‐PSMcable(fornonPoE)orC2RPS‐POEcable(forPoE)
from
yourredundantpowersupplytotheA2switch’s
redundantpowerconnector.
2. AttachtheACpowercordtotheA2switch’sACinputpower
connector.
3. Plugtheredundantpowersupply(ifapplicable)andtheA2
