What Is the DS-C9706-FD-MB?

The ​​DS-C9706-FD-MB​​ is a critical modular backplane component designed for Cisco Catalyst 9000 series switches, specifically engineered to support high-density data center deployments. This 6-slot chassis backplane enables seamless integration of multiple line cards, power supplies, and supervisor engines while maintaining ​​40/100/400 Gbps per-slot bandwidth capacity​​. Unlike traditional fixed-configuration switches, its modular design allows enterprises to scale network resources dynamically based on evolving workloads.

Key features include:

  • ​Multi-layer redundancy​​: Supports N+1 power supply and dual supervisor configurations for mission-critical environments.
  • ​Thermal optimization​​: Adaptive cooling mechanisms prevent overheating in dense deployments.
  • ​Forward compatibility​​: Backward-compatible with existing Catalyst 9500/9600 modules while enabling future 800G upgrades.

Why Choose DS-C9706-FD-MB Over Competing Solutions?

​Criteria​ ​DS-C9706-FD-MB​ ​Legacy Catalyst Chassis​
​Port Density​ Up to 576x 100G ports per chassis Max 288x 100G ports
