Abstract

Power distribution management comprises: detecting an establishment of a connection between a PDU outlet of a PDU and a device to be powered by the PDU; and causing the identification specific to the connection to be shared between the PDU and the device over optical communication in response to establishment of the connection. Corresponding system and power cable are also disclosed. According to embodiments of the present inventive subject matter, the connection relationship between any devices and PDU outlets can be determined efficiently and effectively by checking and matching the connection identifications.

First claim

What is claimed is:

1. A method comprising:
detecting, using a connection detecting unit of a power distribution unit (PDU), an establishment of a connection between a first power outlet of a plurality of power outlets the PDU and a power supply cable for supplying power to a device, wherein the power supply cable comprises at least an electrical line for conveying the power, an optical communication medium, and a plug for connecting the power supply cable to the first power outlet;
generating, in response to the establishment of the connection, a connection identifier via an identification generating unit, the connection identifier for uniquely identifying the first power outlet and the connection;
storing, via an identification storing unit, the connection identifier;
converting, via an electro-optical converting unit, the connection identifier from an electrical representation to an optical signal;
causing transmission of the optical signal representing the connection identifier using a light emitting diode (LED) at the first power outlet coupled to the optical communication medium at the plug.

2. The method of claim 1 , further comprising:
receiving a received optical signal associated with a different connection identifier; and
storing the different connection identifier.

3. The method of claim 1 , wherein said generating the connection identifier comprises generating a random number that has not been utilized for another of the plurality of power outlets.

4. The method of claim 1 , wherein said generating the connection identifier comprises selecting the connection identifier from a plurality of predefined connection identifiers.

5. The method of claim 4 , further comprising indicating the selected connection identifier as no longer available.

6. The method of claim 1 , further comprising updating a power distribution unit outlet connection topographic diagram to indicate the connection between the first power outlet and the device.
