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

Cisco Nexus 2248PQ

You can order front-to-back airflow or back-to-front airflow for cooling. If you are going to install the chassis with its front end facing the cold aisle, you must order the chassis with front-to-back air flow. If you are going to install the chassis with its back end facing the cold aisle, you must order the chassis with back-to-front airflow.

Ports

The Cisco Nexus 2248PQ FEX supports a total of 48 1/10-Gigabit Ethernet/Fibre Channel over Ethernet (FCoE) ports (SFP+) and 4 QSFP+ (16 10-Gigabit ) fabric ports. The Cisco Nexus 2248PQ provides two types of ports: ports for end-host attachments and uplink ports. Uplink ports are differentiated with yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.

The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE and Data Center Bridging (DCB) which increases the reliability, efficiency, and scalability of Ethernet networks by allowing the switches to support multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, SAN, and cluster environments.

Power Supplies

The Cisco Nexus 2248PQ FEX chassis has two bays for front-end AC or DC power supplies. This chassis is fully functional with one power supply, but you can install a second power supply for power redundancy. The power supply is hot swappable during operations.

Table 1-9lists the power supplies that you can order with the Cisco Nexus 2248PQ FEX.

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.
