SwitchClient requires:
Approximately 50 Mb of free disk space on the computer where it is installed.
A network connection to the PowerSwitch server.
SwitchClient does not use a lot of resources on the computer where it is installed. It does use some network bandwidth for communication with the PowerSwitch server, and it causes some extra workload for the PowerSwitch server.
