Router to LAN Connection 27

The RPU2 provides three 10/100/1000 Mbps Ethernet interfaces, where two are electrical and one provides both fiber-optic and electrical connectors.

When both electrical and optical connections are available, you can use only one at a time. For the available SFP options and the interface attributes, refer “The RPU2 Module”.

1Electrical Ethernet interface cable

Electrical Ethernet interfaces usually use category 5 twisted-pair cables, as shown in the following figure.

Figure 16 Ethernet cable

Ethernet cables fit into the following two categories:

Straight-through cable, at both ends of which, the wires are crimped in the RJ-45 connectors in the same sequence. The cable connects different types of devices, such as a terminal device (PC for example) or router to a Hub or LAN switch. The network cables shipped with the router are standard cables.

Crossover cable, at both ends of which, the wires are crimped in the RJ-45 connectors in different sequences. The cable connects the same type of devices, such as PC to PC or PC to router. You can make crossover cables by yourself as needed.

In preparing network cables, shielded cables are preferred for electromagnetic compatibility sake.

2Fiber-optic Ethernet interface cable

For the 10/100/1000M Ethernet interfaces on the RPU2, select single mode or multi-mode optical fibers depending on the type of the installed 1000Base-FX SFPs. As the interfaces that these SFP modules provide use LC-type fiber-optic connectors, you must use fibers with LC-type connectors for them. All these SFPs are hot swappable.

6000 specifications

The 3Com 6000 series, launched in the late 1990s, was a significant advancement in networking technology, designed to meet the growing demands of enterprise-level networking. This series provided powerful solutions for businesses seeking reliable, efficient, and scalable networking capabilities.

At its core, the 3Com 6000 series featured a modular design, allowing companies to customize their networks according to specific needs. This flexibility meant that organizations could add or replace components as their networking requirements evolved, ensuring investment protection and a tailored approach to connectivity. The ability to scale was particularly important for businesses that anticipated growth or change in operational demands.

One of the standout features of the 3Com 6000 was its advanced switching capabilities. The series employed high-performance switching technologies that supported various protocols, including Fast Ethernet and Gigabit Ethernet. This versatility made it suitable for diverse environments, from small offices to large corporate settings. The 3Com 6000 switches were engineered to deliver high throughput and low latency, crucial for applications requiring real-time data transfer.

The series also supported a range of network management tools, enhancing operational efficiency. With SNMP (Simple Network Management Protocol) support, network administrators could easily monitor and manage network performance, troubleshoot issues, and configure devices from a centralized location. This capability significantly streamlined network operations, reducing downtime and optimizing resource allocation.

Security was another significant concern addressed by the 3Com 6000. The series incorporated robust security features, including access control lists (ACLs) and VLAN (Virtual Local Area Network) support. These features allowed network administrators to segment traffic and enforce security policies, protecting sensitive data and ensuring compliance with organizational standards.

Moreover, the 3Com 6000 series was designed with energy efficiency in mind, reflecting a growing awareness of the environmental impact of IT infrastructure. By implementing power-saving features, the series helped organizations reduce their overall energy consumption while maintaining optimal network performance.

In summary, the 3Com 6000 series stood out for its modularity, advanced switching capabilities, extensive management tools, strong security features, and energy efficiency. It represented a forward-thinking solution for enterprises aiming to build robust network infrastructures capable of supporting a wide range of applications and services. As organizations increasingly relied on networked systems, the 3Com 6000 played a crucial role in shaping the landscape of enterprise networking.
