Chapter 1 Product Overview

100BASE-FX Ports

The 10/100 ports on the Catalyst 2900 XL switches provide protocol support for Cisco IP Phones and per-port priority override. Refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide for more information about these features.

Cisco IP Phones—connected to the 10/100 port—must be connected to an AC power source. Unlike the 3524-PWR XL switch, the Catalyst 2900 XL switches do not provide inline power.

For more info on the Catalyst 3524-PWR XL switch, refer to the

Catalyst 3500 Series XL Hardware Installation Guide.

100BASE-FX Ports

The 100BASE-FX ports use 10/125- or 62.5/125-micron multimode fiber-optic cabling. The connection distances between the switch and the attached device can be as follows:

If the switch port and the port on the attached device are configured for half-duplex operation, the connection can be up to 1352 feet (412 meters).

If the switch port and the port on the attached device are configured for full-duplex operation, the connection can be over distances of up to 6562 feet (2 kilometers).

Long-Reach Ethernet Ports

The Long-Reach Ethernet (LRE) ports (Figure 1-4) use one RJ-21 connector to connect up to 24 Cisco 575 LRE customer premises equipment (CPE) devices though unstructured wiring, such as existing telephone lines. The link between the LRE switch port and each CPE device can reach speeds of up to 15 Mbps (full duplex) and distances of up to 4921 feet (1500 meters).

The default mode for each LRE port is speed autonegotiation, half duplex operation. For information about configuring the LRE ports, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

For more information about the Cisco 575 LRE CPE, refer to the Cisco 575 LRE CPE Hardware Installation Guide.

2900 Series XL specifications

Cisco Systems 2900 Series XL routers are integral components of the Cisco Integrated Services Router (ISR) portfolio, designed to support various networking needs for small to medium-sized enterprises. These routers provide an extensive set of features tailored for voice, video, data, and wireless services, making them a versatile choice for organizations looking to streamline their network infrastructure.

One of the standout features of the 2900 Series XL is its modularity. This router is equipped with multiple interface card slots that allow users to customize and scale their network based on current and future requirements. The modular design offers flexibility in integrating various WAN interfaces such as T1/E1, DSL, and Ethernet, enabling businesses to adapt to changing connectivity needs without requiring a complete hardware overhaul.

The 2900 Series XL also supports a wide range of advanced security features. With integrated security protocols, such as firewall capabilities, Intrusion Prevention Systems (IPS), and Virtual Private Network (VPN) support, these routers ensure that sensitive company data remains protected against potential threats. Furthermore, the routers come with Cisco’s Adaptive Security Algorithm, which helps to detect and mitigate real-time attacks.

Another significant characteristic of the Cisco 2900 Series XL is its support for unified communications. The routers have built-in voice capabilities, allowing them to function as a voice gateway. This facilitates features like VoIP (Voice over IP), video conferencing, and even multimedia communication. These tools enhance collaboration and connectivity among team members, contributing to a more productive work environment.

The 2900 Series XL routers also include Cisco's IOS Software, which provides a robust operating system with a rich set of features for routing, switching, and security functions. The software is continually updated to ensure the routers remain compatible with the latest technology and security standards, thereby extending their functionality and lifespan.

In terms of performance, the 2900 Series XL routers are designed for high throughput and low latency, making them suitable for bandwidth-intensive applications. Their architecture supports services such as advanced Quality of Service (QoS) and traffic shaping, ensuring that mission-critical applications receive the bandwidth priority they require.

Ultimately, Cisco's 2900 Series XL routers represent a reliable, flexible solution for organizations looking to enhance their networking capabilities. With their exceptional features, comprehensive security options, and support for diverse applications and services, they play a crucial role in the modern digital landscape.
