The NPE-G1 and NPE-G2 contain an I/O controller, which includes the bootflash and NVRAM
memory. After you install the NPE-G1 or NPE-G2 in a chassis, you can no longer access the
bootflash and NVRAM on the I/O controller. You therefore must make the existing Cisco IOS
software image and configuration files available to the NPE-G1 or NPE-G2, either by putting these
files on a CompactFlash Disk or on a TFTP server.
The NPE-G1 and NPE-G2 include three Gigabit Ethernet interfaces. If you want to use these
interfaces to replace the Ethernet or Fast Ethernet interfaces on the existing I/O controller, you must
configure the new interfaces before they can be used to access the network. If you are also removing
the existing I/O controller, you must remove the configuration for its Ethernet or Fast Ethernet
interfaces.
Note
The NPE-G2 provides a Fast Ethernet Management port, as well as three RJ-45 Gigabit
Ethernet ports.
The NPE-G1 and NPE-G2 use Type 1 CompactFlash Disk memory instead of the Type 2 Flash Disk
memory used in existing I/O controllers. You must transfer any information currently saved on Flash
Disks to CompactFlash Disks so that it can be used after the upgrade to the NPE-G1 or NPE-G2.
