Abstract
A method for determining if a cable is present at a network connection, and adjusting a power signal to the network connection depending upon whether or not a cable is present is disclosed.
Claims17
A method comprising:
- determining whether or not a signal is received from a cable at a network connection;
- and
- ceasing at least one of a plurality of clock signals from a physical (PHY) layer to a media access control (MAC) layer in a network adapter, to adjust a power signal to a low power consumption state if said signal is not received.
The method of claimed 3, wherein said adjusting comprises sending and receiving a plurality of signals in a network adapter from said cable at said network connection.
A storage medium having therein a plurality of instructions that are machine executable, wherein when executed, said instructions operate to determine whether or not a signal is received from a cable at a network connection and cease at least one of a plurality of clock signals from a physical (PHY) layer to a media access control (MC) layer in a network adapter, in order to adjust said power signal to a low power consumption state if said signal is not received.
An apparatus comprising:
- a storage medium having therein a plurality of instructions that are machine executable, wherein when executed, said executing instructions operate to determine whether or not a signal is received from a cable at a network connection and cease at least one of a plurality of clock signals from a physical (PHY) layer to a media access control (MAC) layer in a network adapter, in order to adjust said power signal to a low power consumption state if it is determined that said signal is not received;
- and
- a processor coupled to said storage medium to execute said instructions.
