They are a modular data center-class product line designed for highly scalable 1/10/40/100 Gigabit Ethernet networks with a fabric architecture that scales beyond 17 terabits per second (Tbps)

Designed to meet the requirements of the most mission-critical data centers the switches deliver continuous system operation and virtualized pervasive services

The Cisco Nexus 7000 Series is based on the proven Cisco NX-OS Software operating system with enhanced features to deliver real-time system upgrades with exceptional manageability and serviceability

• Side-to-rear airflow increases the system density in a seven-rack-unit (7RU) footprint optimizing the use of rack space
• The optimized density provides the capability to stack six 4-slot chassis in a 42RU rack
• The fan tray with built-in fan and controller redundancy helps ensure reliability of the system and support for hot swapping of fan trays
• The fan tray is on the top side of the chassis and draws the air from the right side of the chassis through the line card and supervisor slots and propagates it through the empty space on the left side of the chassis
• The air then flows the fan tray on the top side and finally flows out from the vent holes on the back side of the chassis
• Even though Nexus 7004 does not have fabric modules fabric redundancy is still provided
• If the local fabric on one of the I/O modules fails the entire I/O module is taken offline
• All modules including power supplies and the fan tray are accessible from the front
