Preparing for an Upgrade

Note Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup

sequence. See Chapter 10, “Boot Changes in Cisco IOS Release 12.2” 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 will

have to configure the new interfaces before they can be used to access the network. If you are also

removing the existing I/O controller, you will need to 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-G1and 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 do the following procedure.

To ensure a smooth upgrade, do the following procedure only if you are upgrading to an NPE-G1 or

NPE-G2 from an NPE-400 or earlier processing engine.
