Key Advantages

  • Massive Capacity: Up to 768 × 10 Gbps, 384 × 40 Gbps, and 192 × 100 Gbps ports.
  • Redundant Design: Redundant supervisor modules, multiple power/fan trays for continuous operation.
  • Flexible Modularity: Chassis support I/O, fabric, and supervisor modules that can be mixed as needed.
  • Efficient Cooling & Reliability: Front-to-back airflow with variable-speed fans for energy-efficient cooling.

Typical Deployment Scenarios

  • Core and aggregation layers in large enterprise or cloud data centers.
  • High-density campus backbone networks.
  • Virtualized and automated network fabrics requiring high throughput.
  • Scalable platforms for future expansion and module replacements.

Product Description

The 7700 Series offers four modular chassis options:

  • 2-Slot Chassis: Compact form factor; one I/O slot, one supervisor. No separate fabric modules required.
  • 6-Slot Chassis: Mid-range design; up to four I/O module slots, six fabric slots.
  • 10-Slot Chassis: Expanded configuration; up to eight I/O module slots.
  • 18-Slot Chassis: Maximum density for large-scale data centers.

All chassis feature hot-swappable fan trays and power supplies and support front-to-back airflow.
