Installation Requirements Based on the NPE or NSE Installed Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements Installation Requirements Based on the NPE or NSE Installed To ensure that your Cisco 7200 series port adapter configuration is within the router operating limitations, determine your model of network processing engine or network services engine and observe the following guidelines: • For NPE-G1 or NPE-G2, go to the "NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration Instructions" section on page 1-8. • NPE-G1 or NPE-G2 with a Port Adapter Jacket Card-Bandwidth Calculation and Configuration Instructions, page 1-9 • For NPE-400, NPE-300 and NSE-1, go to the "NPE-400, NPE-300, and NSE-1 Bandwidth Calculation and Configuration Instructions" section on page 1-9. • For NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100, go to the "NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration Instructions" section on page 1-11. NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration Instructions Step 1 Step 2 Step 3 For 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 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. Note Do not calculate bandwidth points for an I/O controller if it is installed in the Cisco 7200 VXR router with an NPE-G1 or NPE-G2. With the NPE-G1 or NPE-G2, I/O controllers do not use bandwidth or bandwidth points. Step 4 Step 5 Step 6 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. Make sure that the bandwidth points are evenly distributed between the left (odd-numbered slots) and right (even-numbered slots) buses. Include the I/O controller in your determination of balance for the left odd-numbered slots. Fill the slots in the following order: 2, 1, 4, 3, 6, 5. Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in Chapter 2, "Memory Requirements.". You are finished calculating your port adapter configuration.
