Preparing for an Upgrade
Note
Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup 
sequence. See the 
 for more information.
Upgrading to the NPE-G1 or NPE-G2 is a different procedure than previous processor upgrades because 
of the following considerations:
  •
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. 
Note
If you are upgrading to an NPE-G2 from an NPE-G1, you do not need to perform the following 
procedure.
To ensure a smooth upgrade, perform the following procedure only if you are upgrading to an NPE-G1 
or NPE-G2 from an NPE-400 or earlier network processing engine.
