Chapter 1 Product Overview System Specifications The I/O controller, port adapters, power supplies, and network processing engine slide into their respective chassis slots and connect directly to the router midplane; there are no internal cables to connect. The midplane distributes DC power from the power supplies to the I/O controller, port adapters, fan tray, and network processing engine. The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to packet static random-access memory (SRAM) on the network processing engine, arbitrates traffic across the PCI buses, and generates the clock signals for the port adapters on each PCI bus. The Cisco 7206 operates as either a tabletop or rack-mounted unit. A rack-mount kit is standard equipment included with all Cisco 7206 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 7206 router in an equipment rack are explained in Chapter 3, "Installing the Cisco 7206," the "Rack-Mounting the Cisco 7206" section on page 3-2. If you are not rack-mounting your Cisco 7206, place it on a sturdy tabletop or platform. A fully configured Cisco 7206, 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, refer to Chapter 2, "Preparing for Installation," the "Site Requirements" section on page 2-2.
