Ports

Each port on the Cisco Nexus 2148T FEX is numbered, and groups of ports are numbered based on their function. The ports are numbered from top to bottom and left to right.

Group 1 includes 48 1-Gigabit Ethernet data ports. Group 2 includes four 10-Gigabit Ethernet ports. Figure 1-27shows how ports are numbered and grouped by function.

Power Supplies

The Cisco Nexus 2148T FEX uses a front-end 200-W AC power supply that has front-to-back airflow. The chassis has two bays for two power supplies. Two power supplies can be used for redundancy, but the Cisco Nexus 2148T FEX is fully functional with one power supply. Figure 1-28shows the power supply with two LEDs: one for power status and one for a failure condition. The power supply is hot-swappable. For details on how to install a power supply, see the “Removing and Installing Power Supplies” section on page 3-17.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use a blank filler panel to cover the empty slot. Figure 1-29shows a blank power supply filler panel.

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.
