I have 3 dell PE servers in a rack with a 3000VA APC Smart UPS (from Dell also). How can I connect all 3 servers to the monitoring capabilties of the UPS? There is only one USB cable and and I need 3 (or more for future expansion). Can the Business Edition of the PowerChute software monitor the servers over the network or do I need a hardware solution to connect each server physically? I need all the servers to shut down gracefully when the battery depletes but be restarted when the power is restored.

TIA
