N77-C7706-B33S3E - Cisco ONE Nexus 7706 Chassis N7706 Bundle

A six-slot platform supplied with SUP3E and FAB3

N77-C7706-B33S3E is the Cisco Nexus 7706 bundle with a chassis, one SUP3E supervisor and three FAB3 fabric modules. No power supplies are included in the exact ordering row. The six-slot chassis layout comprises two dedicated supervisor positions and four I/O positions, rather than six line-card slots.

Match the smaller enclosure to the installation plan

The Nexus 7706 occupies 9RU. Its chassis depth is 32 inches, increasing to 38 inches with cable management and doors; a Generation 2 fan tray adds 1.75 inches. Confirm the supplied fan assembly, rack clearance and installation arrangement before choosing it as a space-saving legacy replacement.

Complete the power and interface configuration explicitly

The platform has four power-supply positions and six fabric-module positions, while this bundle specifies three FAB3 modules and one supervisor. Ask for exact power, line-card and optical part numbers with the proposed software release. Those component choices determine the usable system configuration and must not be inferred from chassis capacity.

Set an operational horizon using the model-specific notice

Cisco ended sale of N77-C7706-B33S3E on October 12, 2023 and lists the last support date as October 31, 2028. Eligibility depends on applicable service entitlement. For a legacy expansion, compare the remaining support horizon with a verified migration plan and the interfaces that must be retained.
