Chapter 3 Installing a Cisco 7200 VXR Router

General Tabletop or Workbench Installation

Installing the Chassis in the Rack

After installing the brackets on the chassis, you mount the router by securing the rack-mount brackets to two posts or mounting strips in the rack using the six slotted screws provided. Because the brackets support the weight of the entire chassis, be sure to use all six slotted screws to fasten the two rack-mount brackets to the rack posts. Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5show typical installations in 19-inch, four-post and two-post equipment racks.

We recommend that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the router and any equipment directly above and below it.

To install the chassis in the rack, complete the following steps:

Step 1 On the chassis, ensure that all captive screws on the network services engine (NSE) or network processing engine (NPE), the I/O controller, and each power supply are tightened and the port adapter levers are in the locked position.

Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.

Step 3 Position the chassis so that the front end is closest to you. Lift the chassis and move it to the rack. To prevent injury, avoid sudden twists or moves.

Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the chassis) meet the mounting strips or posts on both sides of the equipment rack.

Step 5 While keeping the brackets flush against the posts or mounting strips, position the router so the holes in the brackets are aligned with those in the mounting strips.

Step 6 Insert all six 10-32 x 3/8 slotted screws (three on each side) through the brackets and into the mounting strip (use the top and bottom bracket holes, as shown in Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5). Using a 1/4-inch flat-blade screwdriver, tighten all the screws.

This completes the procedure for installing the chassis in the rack. Proceed to the “Connecting Port Adapter Cables” section on page 3-19to continue the installation.

General Tabletop or Workbench Installation

The router should already be in the area where you will install it, and your installation location should already be determined. If not, see Chapter 2, “Preparing for Installation,” the “Site Requirement Guidelines” section on page 2-3and the Site Preparation and Safety Guide.

When installing a Cisco 7200 VXR router on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following:

•The router requires at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (the right and left sides of the router).

•The router should be installed off the floor. (Dust that accumulates on the floor is drawn into the interior of the router by the cooling fans. Excessive dust inside the router can cause overtemperature conditions and component failures.)

•There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the router for installing and replacing router field-replaceable units (FRUs), or accessing network cables or equipment.

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. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
