Installation Requirements Based on the NPE or NSE Installed Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements Sample Bandwidth Configuration for the NPE-225, NPE-200, NPE-175, and NPE-150 The following sample configurations are for a Cisco 7200 series router with an I/O controller and NPE-225 installed. The maximum points allowed is 800 points per chassis. Table 1-4 Valid Configuration-Cisco 7200 Series Router with NPE-225 Left Bus Bandwidth Resource Bandwidth Requirement Points Port Adapters: PA-MC-8T1 Low 0 PA-MC-8T1 Low 0 PA-8E Medium 80 I/O Controller: C7200-I/O-2FE/E High 400 Total points left bus: 480 Total high, medium, and low port adapters: 3 high, 2 medium, 2 low Total points per chassis: 740 Right Bus Port Adapters: PA-A3-T3 PA-A3-T3 PA-8E Total points right bus: Bandwidth Resource Requirement Bandwidth Points High 90 High 90 Medium 80 260 The sample configuration in Table 1-4 follows the rule of keeping below the 800 maximum bandwidth points, and having no more than three high-bandwidth port adapters, and having no more than five highand medium-bandwidth port adapters in a chassis with an NPE-225. All three rules must be followed for a configuration to be valid. The I/O controller is considered a port adapter in point calculation. Table 1-5 Invalid Configuration-Cisco 7200 Series Router with NPE-225 Left Bus Bandwidth Resource Bandwidth Requirement Points Port Adapters: PA-FE-TX High 200 PA-MC-8T1 Low 0 PA-MC-8T1 Low 0 I/O Controller: C7200-I/O-2FE/E High 400 Total points left bus: 600 Total high, medium, and low port adapters: 4 high, 3 low Total points per chassis: 780 Right Bus Port Adapters: PA-A3-T3 PA-A3-T3 PA-MC-8T1 Total points right bus: Bandwidth Resource Requirement Bandwidth Points High 90 High 90 Low 0 180 The configuration in Table 1-5 is invalid because, although the bandwidth points are less than 800, there are four high-bandwidth port adapters installed, not three high-bandwidth port adapters as the rules allow. All three rules (no more than 800 bandwidth points, no more than three high-bandwidth port adapters, and no more than five high- and medium-bandwidth port adapters in a chassis with an NPE-225) must be followed for the configuration to be valid. The I/O controller is considered a port adapter in point calculation. 1-12 Cisco 7200 Series Port Adapter Hardware Configuration Guidelines OL-3875-11
