Grounding the Cisco Nexus 7010 Chassis

Before you can ground the chassis, you must have a connection to the earth ground for the data center building. If you installed the Cisco Nexus 7010 chassis into a bonded rack (see the rack manufacturer’s instructions for more information) that now has a connection to the data center earth ground, you can ground the chassis by connecting its grounding ports to the rack. Otherwise, you must connect the chassis grounding ports directly to the data center ground.

Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

•Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire. This lug is supplied with the Cisco Nexus 7010 system accessory kit.

•Grounding screws—Two M4 x 8 mm (metric) pan-head screws. These screws are shipped with the Cisco Nexus 7010 accessory kit.

•Grounding wire—Not supplied with the Cisco Nexus 7010 system accessory kit. This wire should be sized to meet local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. We recommend that you use commercially available 6 AWG wire. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

•No. 1 Phillips screwdriver.

•Crimping tool to crimp the grounding wire to the grounding lug.

•Wire-stripping tool to remove the insulation from the grounding wire.

Connecting the System Ground

After you have moved the chassis into the rack or cabinet, you are ready to connect the system to the data center earth ground. After you ground the chassis, you can ground your ESD wrist strap by connecting it to the chassis.

To connect the system ground to the data center earth ground, follow these steps:

Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire.

Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug as shown in Figure 2-5.

Cisco Systems 7000 series routers are pivotal in the landscape of networking, providing high-performance, reliable solutions for enterprise environments and service providers. These routers were designed to support the growing demands of digital communication, offering robust features that enhance connectivity and streamline network operations.

One of the primary characteristics of the Cisco 7000 series is its modular architecture. This allows for the integration of various interface modules and processing units, enabling organizations to customize their routers according to specific networking needs. The modularity supports scalability, as businesses can upgrade or replace components as their requirements evolve without having to replace the entire system.

The Cisco 7000 series incorporates advanced routing protocols, ensuring efficient data packet management and traffic flow. It supports multiple protocols, including OSPF, BGP, and EIGRP, facilitating seamless integration into a variety of network environments. This flexibility is essential in modern networks, where diverse communication protocols are in use.

Load balancing capabilities are another significant feature of the Cisco 7000 series. This functionality allows for the optimal distribution of network traffic across multiple paths, enhancing performance and redundancy. By ensuring that no single route is overwhelmed, organizations can maintain uptime and improve overall user experience.

Security is a top priority for many businesses, and the Cisco 7000 series addresses this need with built-in security features. It supports Virtual Private Networks (VPNs) and access control lists (ACL) to provide secure remote access and protect sensitive data from unauthorized access. This capability is vital in today’s threat landscape, where data breaches can have far-reaching consequences.

The series also boasts high throughput and low latency, making it suitable for bandwidth-intensive applications like video conferencing and cloud computing. Coupled with Quality of Service (QoS) features, the Cisco 7000 ensures that critical applications receive the bandwidth they need, thereby enhancing overall network performance.

In terms of manageability, the Cisco 7000 routers come equipped with advanced monitoring and diagnostic tools. Network administrators can easily track performance metrics and identify potential issues before they escalate, minimizing downtimes and maintaining business continuity.

In summary, the Cisco Systems 7000 series routers are a sophisticated solution for organizations seeking to optimize their networking infrastructure. With modularity, robust routing protocols, load balancing, security features, high performance, and comprehensive manageability, the Cisco 7000 series stands out as a reliable foundation for successful network operations in an increasingly connected world.
