Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series or Cisco Nexus 6000 Series Switch

Cisco Nexus 2248TP

You can order the Cisco Nexus 2248TP FEX with AC power supplies that have port-side exhaust or port-side intake airflow for cooling or DC power supplies that offer port-side exhaust airflow. The port-side intake airflow components have a black stripe on their fan side surface for easy visual identification. The port-side exhaust airflow components do not have a black stripe.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow direction and that the air intake for those modules is positioned on a cool aisle. If you install a module that uses a different direction of airflow from the other modules in your system, you will see an error message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can over heat and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use

ablank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure 1-26shows a blank power supply filler panel.

Fan Tray

The Cisco Nexus 2248TP (and 2224TP) FEX has one fan tray that is hot swappable during operations. Depending on the arrangement of hot and cold aisles in your data center, you can order port-side exhaust airflow to position the fan side of the FEX chassis in a cold aisle or port-side intake airflow to position the back of the FEX chassis in a cold aisle. Table 1-6lists the part numbers for each of the fan trays that you can use with the Cisco Nexus 2248TP and 2224TP chassis.

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.
