摘要： Briefly, in accordance with one embodiment of the invention, a power brick for use with a network adapter includes: a power supply and at least one signal transformer. The power supply and the signal transformer are physically remote from the network adapter and capable of being electronically coupled to the network adapter via a cable. Briefly, in accordance with another embodiment of the invention, a power brick for use with a network adapter includes: at least two signal transformers. The at least two signal transformers are physically remote from the network adapter and capable of being electronically coupled to the network adapter via a cable. Briefly, in accordance with on more embodiment of the invention, a method of using a power brick with a network adapter includes the following. A high voltage power supply including superpositioned high frequency communications signals is received via a power brick. The voltage of the received signal is reduced. The reduced voltage is transmitted to the network adapter via a cable.
