Software Requirements
For minimum software release information, see the “Software Requirements” section on page 8-4.
Note The NPE-G2 has its own Cisco IOS software image with the prefix “c7200p-” in the software images
filenames, including the boot image. The NPE-G2 does not boot up with a software image with the prefix
“c7200-”. Previous network processing engines, or the network services engine, do not boot up with the
“c7200p-” boot image. They use the prefix “c7200-”.
NPE-G2 Description and Overview
This section contains information about the NPE-G2 components and the system management functions.

Like the NPE-G1, the NPE-G2 provides the functionality of both a network processing engine and I/O
controller. If used without an I/O controller, an I/O controller blank panel must be in place.
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
Adapter Jacket Card.
