Dell PowerConnect W-6000 Power SupplyInstallation Guide0510766-01 | March 2011 1The Dell PowerConnect W-6000 Power Supply adapts electrical power for use with the W-6000. The W-6000chassis has three slots that can hold individual power supplies to support load sharing and fault tolerance.This chapter describes the general features and physical characteristics of the power supply and important powerconsumption management information. The final sections of the chapter cover the steps required to insert andremove power supplies.FeaturesRatingThe Dell W-6000 Power Supply (HW-PSU-400) is rated at 400 W total output and is auto-ranging to accept 85to 264 VAC, at 50 to 60 Hz. Up to three 400 W power supplies can be installed in the W-6000.Load SharingLoad sharing occurs when more than one power supply of the same rating are installed in the W-6000 and turnedon. Load sharing divides the total power load of the W-6000 among all plugged in power supply modules. Sincethe power supplies work together, the effective power capacity of the chassis is increased with each additionalpower supply.RedundancyWhen multiple power supplies are installed, if one becomes unavailable (fails, or is turned off or removed) theremaining power supplies will attempt to provide full power for the W-6000. If the total power load does notexceed the combined rated output of the remaining, operational power supplies, the W-6000 will continue tooperate. For more information on power supply configurations, “Power Management” on page 3.Hot SwapHot swapping should be performed by a trained technician. Hot swapping allows you to replace one failed powersupply while the others provide full power. This makes it unnecessary to shut down the W-6000 during thereplacement procedure.Hot swapping requires that after the target power supply is removed, the total power load does not exceed thecombined rated output of the remaining power supplies.
