N7K-C7004 Cisco Nexus 7000 4 Slot Switch
Cisco N7K-C7004 Nexus 7000 Series 4-Slot Switch Chassis
Scalable Data Center-Class Modular Switching for High-Density 10/40/100G Networks
The Cisco Nexus N7K-C7004 is a compact yet powerful modular switch chassis engineered for small-to-medium data centers and campus core networks that demand enterprise-grade scalability and high availability. As part of the Cisco Nexus 7000 Series, the N7K-C7004 delivers up to 1.92 Tbps of switching capacity and 1.44 billion packets per second (Bpps) forwarding performance in an efficient 7RU footprint.
Designed with an integrated fabric architecture, the N7K-C7004 eliminates the need for external fabric modules, simplifying deployment while reducing hardware complexity and power consumption. The chassis supports four total slots - including dual redundant supervisor slots and two I/O line card slots - enabling flexible port configurations with support for 10GbE, 40GbE, and 100GbE interfaces. This makes it a future-ready platform capable of scaling as bandwidth requirements grow.
Built for nonstop operations, the Cisco Nexus N7K-C7004 features redundant supervisors, hot-swappable power supplies, and fan trays, delivering carrier-class resilience and high availability. Its side-to-rear airflow design is optimized for dense rack deployments, allowing up to six chassis per standard 42RU rack. Running on Cisco NX-OS, the platform supports unified fabric, data center bridging (DCB), and advanced automation - making it ideal for modern, converged data center environments.
Whether deployed as a data center core, aggregation layer, or campus backbone, the Cisco Nexus N7K-C7004 provides the performance, reliability, and scalability required for mission-critical networking.

FAQs:
Q1. Does the N7K-C7004 require fabric modules?
No. Unlike the 9, 10, or 18-slot models, the Nexus 7004 has a built-in fabric system and does not use separate fabric modules (Fabric-1 or Fabric-2).
Q2. What is the maximum port density for this chassis?
With two I/O slots, you can achieve up to 96 ports of 1/10GbE, 12 ports of 40GbE, or 4 ports of 100GbE, depending on the line cards installed.
Q3. Is the power supply included with the chassis?
No, the N7K-C7004 is typically sold as a chassis and fan tray bundle. Power supplies (up to 4) must be purchased separately based on your specific power requirements.
Q4. Can I use supervisor modules from a Nexus 7009 or 7010 in this chassis?
Yes, it is compatible with SUP1, SUP2, and SUP2E supervisor modules, allowing for consistent operations across the Nexus 7000 family.
Q5. What is the benefit of the side-to-rear airflow?
This airflow design allows for increased system density in the rack and is specifically designed for end-of-row or hot-aisle/cold-aisle containment deployments.
