Individual elements of an IT installation can be
controlled individually, but a systems
approach is likely to be more productive


IT devices are interconnected by a network, so
it is not unreasonable to embed system

wide
energy
-
control intelligence into the network
elements themselves

comprises additions to IOS
and the CLI that enable energy management
