Lets see if I can explain this better and you all can let me know how much of this to put in the questionare.
Powerman consists of a client and server process for the purpose of consolidating power management (turn systems on and off as found in a lab environment or remote unmanned dark equipment rooms). A user would login to the system. In this case a Solaris system which provides all the security within the OS and protocols such as ssh. The user runs the client program powerman with options specifying the name of the device to turn on or off and the command of on or off. It can also request status. This client sends the RPC request to the server and the server spawns off a process to handle this request. The server side is configured with information about the devices it manages how they are interacted with (terminal or proprietary protocol, serial line or network connection). The server uses specialized scripts similar to expect functionality to then communicate with the device to power it on or off. This communication is configured to be done over point to point connections or private sub networks. Hope this makes things clearer.
