Cable Reconnection Guidance via Disconnection Sequence Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assembling and reassembling scalable computer systems with multiple server chassis is challenging due to the complexity of cable connections, which can lead to misconfiguration during disassembly and reassembly, affecting system performance.
Innovation Solution
A method and system that electronically monitor and record the disconnection of cables, using visual indicators to guide the reconnection process by illuminating specific port pairs in a sequence that reverses the disconnection order, ensuring accurate reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cables are disconnected and reconnected manually without guidance, then the system can be disassembled for shipment, but the reconnection accuracy deteriorates leading to misconfiguration
Solution Approach 1:
The system records the disconnection sequence and stores it in memory before the actual disassembly occurs. This preliminary recording of the connection state enables accurate reconnection later without relying on manual memory or documentation by technicians.
Solution Approach 2:
Visual indicators provide real-time feedback to technicians during the reconnection process, showing which ports should be connected next based on the recorded disconnection sequence. This feedback mechanism guides the technician through the correct reconnection steps in the proper order.
2Loss of information
If visual indicators illuminate all port pairs simultaneously, then reconnection information is complete, but the complexity of the guidance system increases
Solution Approach 1:
Instead of illuminating all port pairs simultaneously, the system segments the reconnection guidance into sequential steps. Visual indicators illuminate only the current port pair that needs to be connected, breaking down the complex reconnection task into manageable individual steps rather than presenting all connections at once.
Solution Approach 2:
The visual indicators operate periodically, illuminating one port pair at a time in sequence based on the recorded disconnection order. This periodic illumination pattern provides clear temporal structure to the reconnection process, making it easier to follow than simultaneous static indicators.

AI summary
In one embodiment, a computer system has a plurality of chassis interconnected by cables. Each cable initially connects a unique port pair consisting of a port of one chassis and a port of another chassis. The disconnection of cables is monitored, including electronically recording a disconnection sequence in which the port pairs are disconnected by removing each cable from at least one port of the respective port pair. Visual guidance is provided for re-cabling the computer system by sequentially identifying the port pairs in a reversal of the disconnection sequence, wherein identifying each port pair includes illuminating visual indicators associated with the ports of each port pair with a matching illumination pattern.
