The Port Adapter Jacket Card installs into the I/O controller slot on the third PCI bus, mb0. The Port Adapter Jacket Card is designated slot 0, and the port adapter installed in it is designated port adapter slot 7 on the Cisco 7206 VXR router, and slot 5 on the Cisco 7204 VXR router. Guidelines for Installation Cisco 7200 series routers have a finite data-carrying capacity, referred to as bandwidth, that affects the port adapter distribution in the chassis, as well as the number and types of port adapters you can install. To ensure that your Cisco 7200 series router port adapter configuration is within the router operating limits, observe the following guidelines and requirements when planning to install a port adapter, network processing engine or network services engine, or I/O controller. Chapter 2, "Memory Requirements," provides information about various types of memory requirements for the hardware and software that support port adapters. Table 1-1 provides general guidelines for Cisco 7200 series routers. Cisco 7200 Series Port Adapter Hardware Configuration Guidelines 1-6 OL-3875-11
