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.
