Chapter 1 Cisco 7200 VXR Product Overview

Field-Replaceable Units

Adjacent to the power supply bays are two chassis grounding receptacles that provide a chassis ground connection for ESD equipment or a two-holegrounding lug. (See Figure 1-4.)

Three internal fans draw cooling air into the chassis and across the internal components to maintain an acceptable operating temperature. (See Figure 1-4.) The three fans are enclosed in a tray that is located inside the chassis.

Caution To ensure the proper flow of cooling air across the internal components, make sure blank port adapters are installed in unoccupied port adapter slots, and power supply filler plates are installed in unoccupied power supply bays.

The I/O controller, port adapters, Port Adapter Jacket Card, power supplies, and network processing engine or network services engine slide into their respective chassis slots and connect directly to the router’s midplane; there are no internal cables to connect. The midplane distributes power from the power supplies to the I/O controller, port adapters, Port Adapter Jacket Card, fan tray, and network processing engine or network services engine.

The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to packet memory on the network processing engine or network services engine, arbitrates traffic across the PCI buses, and generates the clock signals for the port adapters on each PCI bus.

Note The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in the Port Adapter Jacket Card does support OIR.

The Cisco 7206VXR operates as either a tabletop or a rack-mounted unit. A rack-mount kit is standard equipment included with all Cisco 7200 VXR routers when they are shipped from the factory. The kit provides the hardware needed to mount the router in a standard 19-inch equipment rack or a 2-post rack. Steps for installing the Cisco 7206VXR router in an equipment rack are the same for all Cisco 7200 VXR routers and are explained in Chapter 3, “Installing a Cisco 7200 VXR Router.” If you are not rack-mounting your Cisco 7206VXR, place it on a sturdy tabletop or platform.

A fully configured Cisco 7206VXR, with two installed power supplies and all chassis slots filled, weighs approximately 50 pounds (22.7 kilograms [kg]). For clearance requirements and rack-mount installation considerations, see Chapter 2, “Preparing for Installation,” the “Site Requirement Guidelines” section on page 2-3.

Field-Replaceable Units
