Network Management Device for Powered Device Redeployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power sourcing equipment in networked systems often becomes oversubscribed, leading to insufficient or intermittent power supply to connected devices, causing downtime and making it difficult for administrators to identify and redeploy resources effectively due to lack of information about power capabilities and topological distances.
Innovation Solution
A network management device identifies strained power sourcing equipment and potential substitutes, using power usage information and threshold-based criteria to generate notifications and filter candidates for redeployment, ensuring minimal downtime by redistributing powered devices to equipment with excess capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If more powered devices are connected to power sourcing equipment, then network coverage and device connectivity are improved, but power sourcing equipment becomes oversubscribed and cannot provide sufficient power
Solution Approach 1:
The system performs preliminary identification of power sourcing equipment with excess capacity before power shortages occur. The network management device proactively monitors power usage and identifies candidate PSEs that can accept additional powered devices, enabling preventive redeployment before oversubscription causes service disruption.
Solution Approach 2:
The system implements continuous feedback monitoring of power usage at each PSE. The network management device receives power usage information from PSEs, compares it against capacity thresholds, and automatically triggers redeployment notifications when imbalances are detected, creating a closed-loop control system that maintains power supply reliability.
2Reliability
If power sourcing equipment enters fault state due to oversubscription, then power supply reliability deteriorates, but service downtime increases
Solution Approach 1:
The system performs preliminary identification of power sourcing equipment with excess capacity before power shortages occur. The network management device proactively monitors power usage and identifies candidate PSEs that can accept additional powered devices, enabling preventive redeployment before oversubscription causes service disruption.
Solution Approach 2:
The network management device automatically generates notifications and identifies redeployment candidates without requiring manual administrator intervention. The system self-monitors power usage, self-identifies imbalances, and self-generates corrective actions, reducing the time administrators need to respond to fault conditions.
3Productivity
If administrators manually identify and redeploy powered devices, then power distribution can be optimized, but the process is complex and time-consuming due to lack of information
Solution Approach 1:
The system implements continuous feedback monitoring of power usage at each PSE. The network management device receives power usage information from PSEs, compares it against capacity thresholds, and automatically triggers redeployment notifications when imbalances are detected, creating a closed-loop control system that maintains power supply reliability.
Solution Approach 2:
The network management device serves as an intermediary between power sourcing equipment and administrators. It collects power usage data from PSEs, processes the information to identify imbalances and candidates, and presents simplified notifications to administrators, eliminating the need for administrators to manually gather and analyze complex topological and power capacity information.
4Adaptability or versatility
If power sourcing equipment has excess capacity, then it can accept additional powered devices, but without information systems administrators cannot identify these candidates
Solution Approach 1:
The system implements continuous feedback monitoring of power usage at each PSE. The network management device receives power usage information from PSEs, compares it against capacity thresholds, and automatically triggers redeployment notifications when imbalances are detected, creating a closed-loop control system that maintains power supply reliability.
Solution Approach 2:
