Like the NPE-G1, the NPE-G2 provides the functionality of both a network processing engine and I/O

While its design provides I/O controller functionality, it can also work with any I/O controller supported
in the Cisco 7200 VXR routers or Cisco uBR7200 series routers. The NPE-G2, when installed with an
I/O controller, provides the bootflash and NVRAM that the Cisco IOS software uses to boot.

Note
An I/O controller can be used with the NPE-G2, but an I/O controller is not necessary for system
functionality. Installing an I/O controller in a chassis with the NPE-G2 activates the console and
auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the
NPE-G2. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G2
and I/O controller when both cards are installed.

The NPE-G2 maintains and executes the system management functions for the Cisco 7200 VXR routers
and Cisco uBR7200 series routers and also holds the system memory and environmental monitoring
functions. The NPE-G2 consists of one board with multiple interfaces.

The NPE-G2 can be used with the Port Adapter Jacket Card installed in the I/O controller slot. If you
are upgrading to an NPE-G2 and Port Adapter Jacket Card at the same time, see the Port Adapter Jacket
Card Installation Guide for information about the order of installation of both the NPE-G2 and the Port
