For each port adapter in your system, check the footnotes in
Step 1
If you have any dual-wide port adapters in your system, carefully read the port adapter configuration
Step 2
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
Step 3
write down the bandwidth points requirements. Use the blank
to record your requirements.
Note
Assign each port adapter in your system to a chassis slot.

Make sure that the bandwidth points are evenly distributed between the left (odd-numbered slots) and
Step 5
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

For NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100, go to the
NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration Instructions" section

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.
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.
