Chapter 3 Installing the Router

Setting Up the Chassis

Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Caution Do not place anything on top of the router that weighs more than 10 lb (4.5 kg). Excessive weight on top could damage the chassis.

After the router has been installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the “Installing the Chassis Ground Connection” section on page 3-8.

Rack-Mounting the Chassis

If you are planning to rack-mount the router, do so before making network and power connections. If you need to install network modules or interface cards, you can do so either before or after rack-mounting the router. Ideally, you would install modules and interface cards when you have the best access to the rear panel of the router.

Note The Cisco 3725 requires additional clearance on the left side (as viewed from the front of the chassis) to accommodate cooling fans. This clearance is provided through the use of special brackets. Be sure to install the wide bracket (marked right) on the side of the chassis with the cooling fans.

The Cisco 3725 router is shipped with rack-mounting brackets for 19-inch racks. (See Figure 3-1.)

3700 Series specifications

Cisco Systems 3700 Series routers are a pivotal part of Cisco's portfolio, designed for medium to large enterprises aiming to deliver secure and efficient networking capabilities. Introduced as a versatile solution, these routers provide a comprehensive blend of performance, scalability, and investment protection.

One of the standout features of the Cisco 3700 Series is its modular architecture, allowing organizations to customize their router according to specific needs. This modularity supports various modules for different functions, including voice, data, and video, making the 3700 Series an ideal choice for converged networking environments. Administrators can enhance functionality through an array of WAN and voice interface cards that adapt as the organization's needs evolve.

The 3700 Series is built on Cisco's IOS (Internetwork Operating System), ensuring robust and high-quality performance. It supports advanced routing protocols including EIGRP, OSPF, and BGP, facilitating efficient data transmission across diverse environments. This versatility helps organizations implement sophisticated multi-site connectivity and enables reliable performance in complex network scenarios.

Security is a paramount concern in modern networking, and the Cisco 3700 Series delivers with features such as integrated firewall services, VPN support, and intrusion detection capabilities. These security measures protect sensitive data and ensure secure communication between remote sites—critical in today’s cyber landscape.

Another key characteristic of the 3700 Series is its support for Quality of Service (QoS), which prioritizes time-sensitive traffic such as voice and video. By ensuring that critical applications receive the bandwidth they require, organizations can maintain the quality of service that their users expect.

Moreover, the Cisco 3700 Series is designed with redundancy in mind. Features like dual power supplies and hot-swappable fan trays enhance reliability and uptime, which are crucial for mission-critical applications.

Furthermore, energy efficiency is an increasingly important consideration in network design. The Cisco 3700 Series adheres to modern energy standards, helping reduce the overall carbon footprint while supporting high-performance capabilities.

In summary, the Cisco Systems 3700 Series routers stand out for their modularity, advanced routing capabilities, robust security features, and energy efficiency, making them an optimal choice for enterprises that not only need performance but also flexibility and reliability in their networking solutions. As businesses continue to evolve and adapt, the Cisco 3700 Series is a dependable partner in their connectivity journey, ensuring they can meet current demands while preparing for future challenges.
