Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements Installation Requirements Based on the NPE or NSE Installed Sample Bandwidth Configuration for the NPE-G1 or NPE-G2 This sample configuration is for a Cisco 7200 VXR chassis with an NPE-G1 or NPE-G2 installed. The maximum points allowed for each PCI bus is 600 points. When any I/O controller is installed with the NPE-G1 or NPE-G2, no bandwidth points are used. The Gigabit Ethernet interfaces on the NPE-G1 or NPE-G2 also require no bandwidth points. Table 1-2 Valid Configuration-Cisco 7200 VXR Router with NPE-G1 or NPE-G2 Left Bus Port Adapters: PA-E3 PA-E3 PA-4E1G/120 I/O Controller: C7200-I/O-2FE/E Total points left bus: Bandwidth Points 90 90 0 Right Bus Port Adapters: PA-E3 PA-2E3 PA-2E3 0 180 Total points right bus: Bandwidth Points 90 180 180 450 NPE-G1 or NPE-G2 with a Port Adapter Jacket Card-Bandwidth Calculation and Configuration Instructions The Port Adapter Jacket Card works only with the NPE-G1 or NPE-G2 installed in Cisco 7200 VXR router. Because of the third PCI bus provided by these network processing engines, the Port Adapter Jacket Card PCI bus mb0 provides an additional 600 bandwidth points. Only one port adapter can be inserted into the port adapter slot in the Port Adapter Jacket Card. Because no port adapter is assigned more than 600 bandwidth points, there is no need to do any calculation of points for port adapter slot 5 (Cisco 7204 VXR) or slot 7 (Cisco 7206 VXR), PCI bus mb0. NPE-400, NPE-300, and NSE-1 Bandwidth Calculation and Configuration Instructions Step 1 Step 2 Step 3 Step 4 For the I/O controller and each port adapter in your system, check the footnotes in Table 1-6 to see if any apply to your system. If you have any dual-wide port adapters in your system, carefully read the port adapter configuration document to see what special conditions apply to these port adapters. Calculate the bandwidth points requirements. For the I/O controller and each port adapter in your system, go to Table 1-6 and write down the bandwidth points requirements. Use the blank Bandwidth Calculation Table, page 1-22, to record your requirements. Assign each port adapter in your system to a chassis slot. • Make sure that the total bandwidth points for slots 0, 1, 3, and 5 (left bus) are less than or equal to 600. • Make sure that the total bandwidth points for slots 2, 4, and 6 (right bus) are less than or equal to 600.
