Your system must be powered by only AC or DC power, it cannot useboth at the same time.NOTE: Do not use different versions of power supplies. If you are replacing an AC power supply, you mustreplace all the PSUs in your system with the new versions. Contact Dell Force10 Technical Support if youhave any question regarding the version of PSU used in your system.2500W AC Power RequirementsThe E600i 2500W AC power supply (CAT# CC-E600i-2500W-AC2) can operate at either 100 VAC or220 VAC. If the E600i is connected to an 100 VAC power supply, it provides up to 1500W.DC Power RequirementsEach E-Series system requires at least one DC PEM to operate. Two units are recommended for fullfacility redundancy.Storage RequirementsIf you do not install all of your system components, store them in the original packaging in anenvironment:• constant temperature between -40°F to 158°F (-40°C to 70°C)• non-condensing relative humidity between 5 and 95%• dry, away from direct sunlight, heat, and air conditioning ducts• dust-freeParameter SpecificationsNominal Input Voltage 100 - 120 VAC Requires a minimum of 3 Power Supplies Installed200 - 240 VAC Requires a minimum of 2 Power Supplies InstalledMaximum AC Power Supply Input 16 A @ 100 VAC per module12 A @ 200 VAC per moduleMaximum System Power Input 4.80 KVA @ 100 VAC4.60 KVA @ 220 VACParameter SpecificationsMaximum DC PEM Input Current 75 ASystem 2800 W (9600 BTU/hour)Input Voltage -48 to -60 VDC
