port adapter slot numbering for the Cisco 7200 VXR routers with the Port Adapter Jacket Card installed.
For the Cisco 7202, Cisco 7204, and Cisco 7206 routers, port adapters in odd-numbered slots connect to
PCI bus mb1 (left bus). Port adapters in even-numbered slots connect to PCI bus mb2 (right bus). The
I/O controller connects to PCI bus mb0 (left bus), port adapter slot 0. The I/O controller is considered
part of the left bus when calculating bandwidth points.
For the Cisco 7204VXR and Cisco 7206VXR routers, port adapters in odd-numbered slots connect to
PCI bus mb1 (left bus). Port adapters in even-numbered slots connect to PCI bus mb2 (right bus). The
I/O controller connects to PCI bus mb0 (left bus), port adapter slot 0. The I/O controller is considered
part of the left bus when calculating bandwidth points, except in the case of the NPE-G1 or NPE-G2.
With the NPE-G1 or NPE-G2 installed, the I/O controller connects on the third PCI bus, mb0, which
connects directly into the NPE-G1 or NPE-G2, and so does not use bandwidth points.
The NPE-G1 and NPE-G2 installs only in the Cisco 7204VXR and Cisco 7206VXR routers.
