N77-C7706 - Cisco Nexus 7700 Switches

Configure four I/O slots within the six-slot chassis

N77-C7706 is the 9RU Cisco Nexus 7700 base chassis with four I/O module slots and two dedicated supervisor positions. Cisco includes fan trays and excludes power supplies in this ordering row. It is distinct from a B33 supervisor-and-fabric bundle, so the chassis PID alone does not establish the installed module population.

Measure the complete enclosure before rack allocation

Cisco lists a 32-inch chassis depth, increasing to 38 inches with doors and cable management. A Generation 2 fan tray adds another 1.75 inches. Check the exact cooling assembly and cabinet drawing, including cable routing and maintenance clearance, rather than using the bare enclosure depth as the installation envelope.

Document fabric and power choices as a system

Six fabric-module positions and four power-supply positions are available. These counts are not included quantities. Request the actual supervisors, fabrics, I/O cards, power types and proposed software release on the bill of materials. Review compatibility and power redundancy for that configuration instead of assigning a maximum family throughput to an empty chassis.

Use the exact Nexus 7700 lifecycle milestones

This base PID is listed in Cisco’s Nexus 7700 notice: end of sale was October 12, 2023 and the last support date is October 31, 2028. Continued support depends on the unit’s applicable entitlement. Include contract verification and a migration assessment in a legacy expansion purchase; neither the catalogue listing nor the published date establishes manufacturer stock or coverage.
