Chapter 4 Installing a Cisco Nexus Fabric Extender

Preparing for Installation

Note If the switch is powered up with modules that have different airflow directions, you need to shut down the switch before replacing the modules with the wrong airflow direction.

Maintain ambient airflow throughout the data center to ensure normal operation.

Consider the heat dissipation of all equipment when determining air-conditioning requirements. When evaluating airflow requirements, take into consideration that hot air generated by equipment at the bottom of the rack can be drawn in the intake ports of the equipment above.

If you mount a chimney type of rack, avoid mounting it in a way that is contrary to the direction of flow in the chimney, where the chimney overpowers the system fans.

Chassis Weight

When lifting the system, follow these guidelines:

Disconnect all power and external cables before lifting the system.

Have two people lift the system. The Cisco Nexus FEXs can weigh up to 18.5 pounds (8.4 kg).

Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.

Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.

Installation Guidelines

When installing the Cisco Nexus FEX, follow these guidelines:

Plan your site configuration and prepare the site before installing the chassis. Appendix G, “Site Preparation and Maintenance Records,” lists the recommended site planning tasks.

Record the information listed in Appendix G, “Site Preparation and Maintenance Records,” as you install and configure the device.

Ensure that there is adequate space around the device to allow for servicing the device and for adequate airflow (Appendix B, “Technical Specifications,” lists airflow requirements).

Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix B, “Technical Specifications,”

Ensure that the chassis air intake will be located in a cold aisle and away from the exhaust of other systems.

Ensure that all of the fan tray and power supply modules have the same direction of airflow as follows (the switch supports only one airflow direction for all modules):

Port-side intake airflow modules have black stripes.

Port-side exhaust airflow modules have no colored stripes.

Note If the switch is powered up with modules that have different airflow directions, you need to shut down the switch before replacing the modules with the wrong airflow direction.

2000 specifications

In the year 2000, Cisco Systems, a leading technology company, was at the forefront of networking and communication solutions. With a rich history of innovation, Cisco solidified its position as a global leader in providing advanced networking technologies, hardware, and software.

One of the most significant features of Cisco in 2000 was its comprehensive portfolio of routers and switches. The company was known for its powerful routers, which were essential for managing internet traffic efficiently. Cisco’s Catalyst series of switches provided high levels of performance and scalability, enabling companies to build robust local area networks (LANs). These devices supported Ethernet technologies and catered to the growing demands of businesses for faster and more reliable connectivity.

In the late 1990s and early 2000s, the internet was experiencing rapid growth, and Cisco capitalized on this surge by introducing technologies that facilitated internet protocol (IP) networking. Its focus on developing IP-based solutions allowed businesses to integrate voice, video, and data services seamlessly over a single network. This was a significant advancement known as convergence, fundamentally changing how organizations approached communication.

Another characteristic of Cisco in 2000 was its commitment to security. As businesses began to increase their reliance on the internet, the risks associated with cyber threats also grew. Cisco developed security solutions such as firewalls and intrusion detection systems to help protect networks from potential attacks. The introduction of the Cisco Secure Network Architecture laid the foundation for comprehensive network security strategies.

Cisco also emphasized research and development, consistently investing in new technologies and innovations. The company was a pioneer in developing optical networking solutions, which enabled faster data transmission over long distances. This was crucial for supporting the growing bandwidth demands of the era.

Furthermore, Cisco’s collaboration with various technology partners and its global presence allowed it to provide customers with tailored solutions to meet diverse needs across different industries. The introduction of certification programs, like the Cisco Certified Network Associate (CCNA), helped create a skilled workforce equipped to deploy and manage Cisco technologies effectively.

In summary, Cisco Systems in 2000 showcased a blend of powerful routing and switching capabilities, a commitment to internet security, and innovative solutions that paved the way for future networking technologies. Its focus on convergence and relentless drive for high-performance networking made it a vital player in the evolving landscape of technology during this period.
