Spine Switch Detachable Connectors for Hot-Swappable Leaf Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network switches require extensive and costly maintenance efforts due to the need to power down and reconfigure the entire system for replacing faulty elements, such as a faulty switching ASIC in a director switch, which can lead to significant downtime and inefficiencies.
Innovation Solution
The integration of a spine switch with a support board and detachable connectors that allow for the decoupling and recoupling of leaf switches without disconnecting flexible cables, enabling the removal and replacement of faulty elements without shutting down the entire network switch, utilizing a mechanism like a jack mechanism with a rod for movement and a second rail for non-blocking connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire network switch is powered down for replacing faulty elements, then reliability of replacement is ensured, but downtime increases and productivity decreases
Solution Approach 1:
The network switch is divided into modular components (line cards, switching fabric, management modules) that can be independently replaced. The detachable connectors enable separation of these modules without affecting the entire system, allowing faulty elements to be replaced while the rest of the switch remains operational.
Solution Approach 2:
The system transitions from a static, monolithic architecture to a dynamic, modular architecture where components can be hot-swapped. The detachable connectors enable dynamic reconfiguration of the switch architecture during operation, allowing maintenance without complete system shutdown.
2Ease of repair
If detachable connectors are used to enable module replacement, then ease of repair improves, but device complexity increases
Solution Approach 1:
The detachable connectors are designed with universal interfaces that can accommodate different module types while maintaining consistent connection protocols. This multi-functionality allows the same connector design to serve multiple purposes across different switch configurations, simplifying the overall system despite the added replaceability feature.
3Adaptability or versatility
If flexible cables are used to connect detachable connectors, then adaptability improves, but connection stability may deteriorate
Solution Approach 1:
Flexible cables with sufficient length are used to connect the detachable connectors, providing the necessary adaptability for module movement and positioning. The flexibility of these cables allows them to accommodate the mechanical movements required for module insertion and removal while maintaining stable electrical connections throughout the range of motion.

AI summary
A spine switch for a network switch comprises a support board that supports at least one first switch. The spine switch further includes a first set of connectors at a first edge of the support board that detachably connect to one or more first leaf switches to communicatively couple and decouple the at least one first switch from the one or more first leaf switches.
