Figure 1. Cisco Nexus 7700 Switches
All Cisco Nexus 7000 Series chassis use a passive mid-plane architecture, providing physical connectors and copper traces for interconnecting the fabric modules and I/O modules for direct data transfer. All inter-module switching is performed via crossbar fabric ASICs on the individual I/O modules and fabric modules.
A scalable, fully distributed fabric architecture uses up to six fabric modules to deliver up to 1.32 Tbps per slot of bandwidth in the Cisco Nexus 7700 6-, 10-, and 18-slot switches on day one. In case of the Cisco Nexus 7700 2‑slot chassis, the fabric modules are not required since it uses a single I/O module. The midplane design on the 2‑, 6-, 10-, and 18-slot chassis supports flexible technology upgrades as your needs change, providing ongoing investment protection. Future fabric modules will allow higher bandwidth capabilities on the platform.

Common Components on Cisco Nexus 7700 Switches
All Cisco Nexus 7700 Switches have the following components:
● An integrated cable management system, custom designed for the 2-, 6-, 10-, and 18-slot switches, supports the cabling requirements of a fully configured system at either or both sides of the switch, providing outstanding flexibility. All system components can easily be removed with the cabling in place, providing ease of maintenance with no disruption.
● A series of LEDs at the top of the chassis (except in case of the Cisco Nexus 7700 2-slot chassis) provides a clear summary of the status of the major system components, alerting operators to the need to conduct further investigation. These LEDs report the power supply, fan, fabric, supervisor, and I/O module status.
Energy-Efficient Design
The Cisco Nexus 7700 Switches use 3.5-kW and 3-kW power supplies that are 96 and 90 percent efficient or greater, so less power is dissipated as heat, and more power is available for the system to use than with typical power supplies. These high-efficiency power supplies allow smaller power configuration and provide flexible power provisioning.
The fan trays in the switches have variable speed fans that adjust to compensate for changing thermal characteristics and use less power at typical operating conditions. Standard fan trays are included as part of the Nexus 7700 2-, 6-, 10-, and 18-slot chassis. The Nexus 7700 6-, 10-, and 18-slot chassis also support optional generation 2 fan trays. All fan trays provide NEBS compliance in combination with the rest of the components of the chassis for specific system configurations. Additionally, the generation 2 fan trays provide NEBS Level-3 acoustic compliance and short term operation at 55C for the Nexus 7700 6-, 10-, and 18-slot chassis if configured with the Nexus 7700 M3 100G I/O modules or future I/O modules.
Consolidation of multiple switches to Cisco Nexus 7700 Switches is made possible by the high density of ports on the switches combined with high-performance device virtualization, comprehensive reliability, and availability features. This consolidation capability provides multiple benefits such as reduced power, cooling, and space requirements to save on costs.
