Shock and Vibration

Note To predict and prevent strong EMI, you might need to consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use twisted-pair cable with a good distribution of grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. You may want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

Shock and Vibration

The Nexus 7000 Series has been shock- and vibration-tested for operating ranges, handling, and earthquake standards to Network Equipment Building Standards (NEBS) Zone 4 per GR-63-Core.

Grounding

The Nexus 7000 Series is sensitive to variations in voltage supplied by the AC-power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from the memory or cause components to fail. To protect against these types of problems, you should always properly ground power cables.

Power Source

You should use a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). We recommend that the Nexus 7000 Series have two separate AC-power sources. For each power supply, connect each of its AC-power cables to an independent power source.

Before you connect the power supplies to the AC power, you must install the power supplies in the Nexus 7010 chassis and you must have one 20A AC receptacle for each power cable that you need to connect to the Nexus 7010 power supplies. Each receptacle should be on a separate circuit and should be located on the rack within reach of the power cables when they are attached to the power supplies.

7000 specifications

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.
