Chapter 2 Preparing for Installation

Site Requirement Guidelines

When planning your rack installation, consider the following guidelines:

•If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis. Figure 2-2shows the chassis footprint, which you need if you are designing a customized shelf. We recommend that you use the rack-mount kit designed for Cisco 7200 VXR routers.

Caution To prevent chassis overheating, never install the Cisco 7200 VXR in an enclosed rack or room that is not properly ventilated or air-conditioned.

•Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving port adapters, connecting cables, or replacing or upgrading components). Otherwise, allow 19 inches (48.3 cm) of clearance to remove Cisco 7200 VXR FRUs.

•If you are planning to install the cable-management brackets on a Cisco 7200 VXR router that you are rack-mounting from the front, you must install the cable-management brackets and the rack-mount brackets before you install the chassis in the rack.

•Provide an adequate chassis ground (earth) connection for your router chassis.

Note We strongly recommend that you provide a chassis ground connection. See the “Attaching a Chassis Ground Connection” section on page 3-17in Chapter 3, “Installing a Cisco 7200 VXR Router” for instructions.

To properly install a Cisco 7200 VXR chassis in a rack, see the instructions in the “Rack-Mounting a Cisco 7200 VXR Router” section on page 3-2in Chapter 3, “Installing a Cisco 7200 VXR Router.”

Temperature and Humidity Requirements

Table 2-1lists the operating and nonoperating environmental site requirements. The ranges listed are those within which the Cisco 7200 VXR routers continue to operate; however, a measurement that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols.
