Abstract
A programmable logic circuit assigns a value to an outlet of a power distribution unit (PDU) that comprises a power source at an input of the PDU and at least one light-emitting diode (LED) associated with the outlet. The programmable logic circuit sends the value to a program on a hardware device that comprises one or more power supplies. The programmable logic circuit receives information from the program. Subsequently, an illumination state of the LED is modified based on the information.
Claims3
A system comprising:
- a first power source;
- a hardware device;
- an electrical outlet;
- an indicator hardware set;
- and
- a programmable logic circuit;
- wherein:
- the hardware device comprises a power supply;
- the hardware device is powered by the electrical outlet;
- the power supply is disconnectably electrically connected to the electrical outlet;
- the first power source is disconnectably electrically connected to the electrical outlet;
- the electrical outlet is structured, connected and/or located so that electrical power is supplied from the first power source to the power supply through the electrical outlet;
- the electrical outlet is located in close proximity to the indicator hardware set;
- the hardware device is structured, connected and/or programmed to:
- determine an operational status information of the power supply, the operational status information is related to the status of the power supply, the operational status information including a first value;
- and
- generate a signal that includes the operational status information;
- and
- send the signal through a communication network to the programmable logic circuit;
- and
- the programmable logic circuit is structured, connected and/or programmed to:
- assign the first value to the electrical outlet, the first value including a first identifier identifying the electrical outlet, and a first name representing the first power source;
- send the first value to a program on the hardware device that comprises one or more power supplies and is powered by the electrical outlet;
- receive the signal, through the communication network, from the hardware device related to the status of the one, or more, power supplies coupled to the electrical outlet;
- and
- modify an indication status of the indicator hardware set based, at least in part, on the signal.
