PoE Module Power Error Detection and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Power over Ethernet (PoE) technologies face challenges in effectively displaying power errors across multiple modules supplied with PoE, leading to inadequate power error detection and notification within networked systems.
Innovation Solution
A module device with a network interface powered by PoE, where modules can detect and notify each other of power supply issues, using indicators and positional information to display power errors, ensuring that power errors are satisfactorily displayed and communicated across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power is supplied to multiple modules using PoE technology, then power supply convenience is improved, but power error detection and display capability deteriorates
Solution Approach 1:
The system segments the power error detection function by assigning specific roles to different modules: the first module (module 151) detects power supply status and generates error messages, while the second module (module 152) receives and displays error notifications. This segmentation enables effective power error detection across multiple PoE-supplied modules without requiring each module to have full detection capabilities.
Solution Approach 2:
The network switch (106) acts as an intermediary that facilitates power error detection and communication. It supplies PoE power to modules, transmits power status information, and enables communication between modules regarding power errors. This intermediary role allows the system to maintain simple PoE power supply while achieving reliable power error detection through network-based information exchange.
2Loss of information
If power error notification is implemented across networked modules, then power error visibility is improved, but system complexity increases
Solution Approach 1:
The network switch (106) performs multiple functions: it supplies PoE power to modules, transmits power status information, and enables communication between modules. By making the network switch universal and multi-functional, the system achieves power error notification without adding dedicated detection or communication hardware, thereby minimizing system complexity while improving power error visibility.
Solution Approach 2:
Modules autonomously detect their own power supply status and generate error messages when power issues occur. The first module (module 151) automatically detects power errors and sends notifications to the second module (module 152) without requiring external intervention. This self-service approach enables effective power error notification while keeping the system simple and autonomous.

AI summary
Provided is a plurality of modules containing a computer that has a network interface to which power is supplied with PoE. The plurality of modules is connected to a network. A first module that receives a response indicating that requested power is not able to be supplied from the network performs a process of displaying an abnormality. The first module notifies a second module of the abnormality via the network. The second module controls display of the abnormality when the second module is notified of the abnormality.
