Chapter 6 The W-6000 Power Supply Module The Dell PowerConnect W-6000 controller Power Supply adapts electrical power for use with the W-6000 controller. The W-6000 chassis 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 power consumption management information. The final sections of the chapter cover the steps required to insert and remove power supplies. Features Rating The Dell W-6000 Power Supply (HW-PSU-400) is rated at 400 W total output and is auto-ranging to accept 85 to 264 VAC, at 50 to 60 Hz. Up to three 400 W power supplies can be installed in the W-6000 controller. Load Sharing Load sharing occurs when more than one power supply of the same rating are installed in the W-6000 controller and turned on. Load sharing divides the total power load of the W-6000 among all plugged in power supply modules. Since the power supplies work together, the effective power capacity of the chassis is increased by with each additional power supply. Redundancy When multiple power supplies are installed, if one becomes unavailable (fails, or is turned off or removed) the remaining power supplies will attempt to provide full power for the W-6000 controller. If the total power load does not exceed the combined rated output of the remaining, operational power supplies, the W-6000 will continue to operate. For more information on power supply configurations, "Power Management" on page 25. Hot Swap Hot swapping should be performed by a trained technician. Hot swapping allows you to replace one failed power supply while the others provide full power. This makes it unnecessary to shut down the W-6000 controller during the replacement procedure. Hot swapping requires that after the target power supply is removed, the chassis's total power load does not exceed the combined rated output of the remaining power supplies.
