"ping" will test for connectivity to a device at the Ethernet Address Level...but that does not mean the device's software is actually talking to the network or responding to the network. "ping" WILL tell you the device is wired up and has power applied to it's network interface board.
The power rating of the electrical device or system. The duration for which the device or system is in use. The efficiency of the device or system in converting electrical energy into useful work.
