My company is in the process of upgrading all of the UPS's (Uninterrupted Power Supplies) in our access switch closets.  In our current configuration, we utilize Catalyst 3560G-48PS-S switches and have between two and four switches per closet.  Within the next year we will be adding new switches to several of our closets due to upcoming projects and I am trying to make sure that our new UPS's will not only handle our present power requirements, but also our future requirements.  According to the documentation provided by Cisco for this model of switch, the Maximum Power Supply Rating is 590W with a 370W POE switch maximum.  My question is, in determining the power requirements for this model of switch and assuming I am using the switch maximum of 370W for POE, would my wattage be 590W or 960W (590 + 370)?
