Hello Brian Yes, it is hot-plug. At the bottom of this spec sheet it mentions that is hot plug:     Thanks
Hello All,   I purchased a couple of the Dell 2700W UPS devices last year, and have recently purchased the network management cards.   Can anyone tell me if I need to shutdown the UPS to install the network management cards, or can I hot plug them into a running UPS?   Thanks, Brian
