Abstract
The present invention is related to a method and apparatus for monitoring and controlling devices comprising connecting an external manager to a communication protocol, connecting a first device to the external manager, assigning an IP address to said first device publishing a second IP address from the first device, connecting a second device to said first device such that it obtains the said second IP address, publishing a third IP address from said second device.
Claims20
A method of monitoring and controlling self-configuring IP addressable devices in an IP connected system comprising:
- connecting a first power distribution unit to an external network manager via a communication protocol;
- assigning an IP address to said first power distribution unit, said first power distribution unit configuring itself as a master device based on the connection to the external network manager, said IP address allowing said external network manager to address communications specifically to said first power distribution unit;
- publishing a first sub-node IP address from the first power distribution unit;
- and
- connecting a second power distribution unit to said first power distribution unit such that said second power distribution unit obtains said first sub-node IP address, said second power distribution unit configuring itself as a slave device based on the connection to the first power distribution unit, said first sub-node IP address allowing said external network manager to address communications specifically to said second power distribution unit;
- wherein each of said first power distribution unit and said second power distribution unit is self-configurable as a master device and as a slave device, such that the second power distribution unit reconfigures itself as a master device when connected to the external network manager and assigned the IP address, and the first power distribution unit reconfigures itself as a slave device when connected to the second power distribution unit and obtaining the first sub-node IP address.
A system for monitoring and controlling self-configuring IP addressable devices comprising:
- a first power distribution unit connected to an external network manager via a communication protocol and assigned a first IP address, said first power distribution unit configuring itself as a master device based on the connection to the external network manager, said IP address allowing said external network manager to communicate specifically with said first power distribution unit;
- and
- a second power distribution unit connected to said first power distribution unit and assigned a sub-node IP address, said second power distribution unit configuring itself as a slave device based on the connection to the first power distribution unit, said sub-node IP address allowing said external network manager to communicate specifically with said second power supply device;
- wherein said first power distribution unit and said second power distribution unit communicate with the external network manager via the same communication protocol.
