Hot-Swappable Network Switch Enclosure Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network switch maintenance requires disconnecting and reconnecting network cables for repairs or replacements, leading to cable connector failures and inefficiencies in serviceability and performance.
Innovation Solution
A hot swappable solution that disaggregates switch faceplate network cable connectors from internal components, allowing for the removal and replacement of ASIC modules without disconnecting network cables, using disconnectable internal connections for minimal signal loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If network cables are disconnected to repair or replace switch components, then ease of repair is improved, but reliability deteriorates due to cable connector failures and network disruption
Solution Approach 1:
The patent divides the network switch into modular components: a fixed portion containing the cable connectors and a removable portion containing the ASIC module. This segmentation allows the ASIC to be replaced without disconnecting cables, as the modular design enables the removable portion to be detached and replaced while the fixed portion with connectors remains in place and maintains cable connections.
2Ease of operation
If network cables are repeatedly connected and disconnected, then ease of operation is improved for maintenance, but reliability worsens due to connector failures
Solution Approach 1:
By segmenting the switch into fixed and removable portions, the patent eliminates the need to disconnect cables during maintenance. The fixed portion with connectors stays connected, while only the removable portion containing the ASIC needs to be detached and replaced, thus maintaining cable integrity and reducing connector wear.
3Loss of time
If network cables are left inactive after damage, then loss of time is reduced for replacement decisions, but productivity deteriorates due to unused cables occupying space and requiring management
Solution Approach 1:
The patent enables recovery of cable connections by designing a system where the cable-connected fixed portion remains in place while only the internal ASIC module is replaced. This eliminates the need to discard entire cable assemblies, allowing cables to be recovered and reused, thus improving productivity by reducing cable management overhead.

AI summary
A system for hot swapping a network switch without disconnecting the network switch connectors is provided. The system disaggregates the switch faceplate network cable connectors from the internal components of the network switch so that the internal switch components may be removed from the switch without disconnecting the switch network cables.
