Cisco 7200 Series Port Adapter Installation Requirements
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.

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.

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.
