Chapter 4 Installing a Cisco Nexus Fabric Extender

Removing and Installing Components

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, remove it from the slot as follows:

If you are removing a filler panel from a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, push its thumb latch to the left and pull the panel out of the chassis.

If you are removing a filler panel from a Cisco Nexus 2148T FEX, loosen its captive screw, and then pull the panel out of the power supply bay.

Step 3 Hold the replacement power supply by its handle and position it so that the captive screw is on the left, and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.

Step 4 Secure the power supply to the chassis as follows:

If you are installing a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, make sure that the thumb latch engages with the chassis so that the power supply is held in the slot.

If you are installing a Cisco Nexus 2148T, fasten the power supply to the chassis by screwing its captive screw into its hole in the chassis and tightening it.

Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco Nexus 2000 Series FEX to your outlet receptacle. See the “Jumper Power Cord” section on page C-8.

Step 5 Connect the other end of the power cable to an AC power source.

Caution 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.

Step 6 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 a DC Power Supply

Caution If you are using the Cisco Nexus 2200 platform FEX with one DC power supply, removing the power supply causes the device to shut down. If you are using two power supplies and you remove one of them, the device continues to operate.

To remove a DC power supply, follow these steps:

Step 1 Shut off the DC power to the power supply at the circuit breaker. Make sure that both LEDs are off. Step 2 Unfasten the positive power cable from the negative (-) terminal.

Step 3 Unfasten the negative power cable from the positive (+) terminal.

Step 4 Press the thumb latch to disengage the power supply from the chassis and use the handle to pull it part way out of the 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.
