For example, the indicated information can be phase information of a power signal provided by the socket connector. Other indication can be indicated as well. For example, the indicated information can be a branch indication indicating whether a power strip has more than one branch circuits. For example, the indicated information can be provide information pertaining to an intelligent power strip that has a different switching or measure function for each outlet, or that has a power-on sequence order for the outlets of the intelligent power strip.
