What type of power cords do the power supplies use?
The power cords available for these switches are sized for the increased current that can be drawn when using PoE. As a result, they are uncommon and you may want to consider having a spare on hand. They can be purchased through the HP Parts Web site at: http://www.hp.com/buy/parts (at the top of the page select a different country if needed). Note that the 1500W power supply is 200V only.
