Cisco 7200 Series Port Adapter Hardware Configuration Guidelines
OL-3875-11
Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements
Installation Requirements Based on the NPE or NSE Installed
Step 5 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.
Step 6 Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in Chapter 2.
You are finished calculating your port adapter configuration.
Note Dual-width port adapters occupy two horizontally aligned port adapter slots when installed in a
Cisco 7200 series router; however, dual-width port adapters do not use both PCI bus mb1 (left bus) and
PCI bus mb2 (right bus) when operating in the router.
The dual-width PA-A2 port adapter uses only PCI bus mb2 (right bus) when installed in a Cisco 7200
series router.
The dual-width PA-12E/2FE port adapter autoselects PCI bus mb1 (left bus) or PCI bus mb2 (right bus)
based on bandwidth availability—the port adapter selects the PCI bus that has the most available
bandwidth. Therefore, do not include the bandwidth points for the PA-12E/2FE when calculating the
combined bandwidth point total for a combination of installed port adapters in PCI bus mb1 (left bus)
and PCI bus mb2 (right bus). Instead, add the bandwidth points for the PA-12E/2FE to the PCI bus that
has the most PCI bus bandwidth availability (the PCI bus the PA-12E/2FE will autoselect) after
completing the initial calculation.
Sample Bandwidth Configuration for the NPE-400, NPE-300, and NSE-1
This sample configuration is for a Cisco 7200 VXR chassis with an NPE-400 installed. The maximum
points allowed for each PCI bus is 600 points. The I/O controller is considered a port adapter in
bandwidth point calculation.
