Abstract
A system is disclosed as including a power supply, a secondary capacitive storage device connected to the power supply, and multiple network devices powered by the power supply. The system further includes a designated device for transmitting a power loss condition over a network, where upon detection of an imminent interruption of power from the power supply the secondary capacitive storage device exclusively powers the designated device during transmission of the power loss condition, and the multiple network devices are intentionally powered off.
Claims20
A system comprising:
- a power supply;
- a secondary capacitive storage device connected to the power supply;
- multiple network devices powered by the power supply;
- a monitoring device configured to detect an imminent interruption of power from the power supply;
- one or more switches configured to disconnect the multiple network devices from the power supply;
- and
- a designated device for transmitting a power loss condition over a network, where upon the detection of the imminent interruption of the power from the power supply the secondary capacitive storage device powers the designated device during the transmission of the power loss condition, and where the one or more switches disconnect the multiple network devices from the power supply in response to the detection of the imminent interruption of the power from the power supply.
A system comprising:
- means for transmitting a power loss condition over a network;
- means for providing power to a plurality of components of a network device;
- means for disconnecting the plurality of components from the power;
- and
- means for providing backup power to the network device independent from the means for providing power, where upon detection of an imminent interruption of power from a primary power supply, the means for backup power is designated to the means for transmitting the power loss condition over the network, and where the plurality of components are disconnected from the power in response to the detection of the imminent interruption of the power.
Software encoded in one or more computer-readable media where the software is executable by a system that causes the system to:
- transmit a power loss condition over a network including one or more network devices;
- detect an imminent interruption of power to a network device, where the network device comprises multiple subsystems;
- provide backup power to the network device;
- and
- upon detection of the imminent interruption of the power from a primary power supply, disconnect the multiple subsystems from the power, where the backup power is exclusively designated to transmit the power loss condition over the network.
