Cisco Nexus 7000 series switches provide the foundation for Cisco Unified Fabric. 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 4-Slot chassis with two I/O module slots supports up to 96 x 1 and 10 Gigabit Ethernet ports, 12 x 40 Gigabit Ethernet ports and 4 x 100 Gigabit Ethernet ports, meeting the needs of small to medium-size data centers, co-locations, access- and aggregation-layer deployments, high-speed core deployments, and smaller operation zones. The Cisco Nexus 7000 4-Slot chassis also has two dedicated supervisor slots to provide full redundancy and high availability. The 4-slot chassis does not require fabric modules. The local I/O module fabrics are connected back to back to form a two-stage crossbar that interconnects the I/O modules and the supervisor engines. The backplane capacity is determined by the installed I/O modules.
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 up to 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 up to 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.
