Chapter 4 Installing a Cisco Nexus Fabric Extender

Removing and Installing Components

Step 5 Place your other hand under the power supply to support it while you slide it out of the chassis. Place the power supply on an antistatic surface.

Step 6 If the power supply bay is to remain empty, install a blank power supply filler panel.

Installing a DC Power Supply

In a system with dual power supplies, connect each power supply to a separate power source. If a power source failure occurs, the second source will most likely still be available.

Caution Be sure that the power supply that you are installing has the same airflow direction as the fan tray module and the other power supply. Either all of the modules must have port-side exhaust airflow (blue or no color on the front of the module) or all of the modules must have port-side intake airflow (red or black color on the front of the module). To prevent over heating, the switch does not support more than one airflow direction for the chassis.

To install a power supply, follow these steps:

Step 1 Ensure that the system (earth) ground connection has been made for the chassis. For ground connection instructions, see the “Grounding the System” section on page 4-7.

Step 2 If the power supply bay has a filler panel, push and hold the thumb latch to the left, and then slide the filler panel out of the power supply bay.

Step 3 Hold the replacement power supply by the handle and position it so that the thumb latch is on the right, and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.

Step 4 Engage the thumb latch so that the power supply is firmly held in place in its slot.

Step 5 Fasten the positive cable to the negative (-) terminal.

Step 6 Fasten the negative cable to the positive (+) terminal.

Step 7 Turn on the power at the circuit breaker.

Step 8 Verify power supply operation by checking that the power supply LED is green. For information about what the power supply LEDs indicate, see the “Power Supply Status” section on page E-3.

Removing and Installing a Fan

The Cisco Nexus 2300 Series FEXs support three fans, but the FEX needs only two fans for operation. The other fan is for redundancy. Individual fans are designed to be removed and replaced while the system is operating, without causing an electrical hazard or damage to the system.

If you are replacing a fan tray on a Cisco Nexus 2200 Series FEX, or Cisco Nexus 2148T FEX, see the “Removing and Installing the Fan Tray” section on page 4-21.

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.
