Preparing for an Upgrade
Note Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup
sequence. See the “Boot Changes in Cisco IOS Release 12.2” section on page 10-2 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.
