Upgrading ROMmon on the NPE-G1 or NPE-G2 Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image instead of having to replace hardware (NPE-G1 or NPE-G2) to get a new image. Note ROMmon can be upgraded on the NPE-G1 or NPE-G2, but cannot be upgraded on any other network processor engine for the Cisco 7200 series routers. There are two ROMmon images: one ReadOnly image (the original image that shipped with your system) that is always available if you have the following: • NPE-G1 hardware EPROM version 4.0 with NPE-G1 ROMmon version 12.3(4r)T1 or later • NPE-G2 hardware You can choose to configure the system to point to the second ROMmon image, the upgradeable ROMmon image. At bootup, the system starts with the ReadOnly image and then, if configured, jumps to the upgradeable image. If the upgradeable ROMmon image fails to boot, the router will mark this ROMmon image as invalid and revert to the ReadOnly image. The first time a new ROMmon image is executed, you must allow the system to boot ROMmon before doing any additional resets or power cycling. If the ROMmon-executing process is interrupted, the stem interprets this as a bootup failure of the new ROMmon image. The router reverts to the ReadOnly image. Note The ROMmon upgrade image is marked as invalid if it fails to boot. Do not reset the router when it is performing an initial bootup.

Upgrading ROMmon on the NPE-G1 or NPE-G2
Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image
instead of having to replace hardware (NPE-G1 or NPE-G2) to get a new image.
Note
ROMmon can be upgraded on the NPE-G1 or NPE-G2, but cannot be upgraded on any other network
processor engine for the Cisco 7200 series routers.
There are two ROMmon images: one ReadOnly image (the original image that shipped with your
system) that is always available if you have the following:
•
NPE-G1 hardware EPROM version 4.0 with NPE-G1 ROMmon version 12.3(4r)T1 or later
•
NPE-G2 hardware
You can choose to configure the system to point to the second ROMmon image, the upgradeable
ROMmon image. At bootup, the system starts with the ReadOnly image and then, if configured, jumps
to the upgradeable image. If the upgradeable ROMmon image fails to boot, the router will mark this
ROMmon image as invalid and revert to the ReadOnly image.
The first time a new ROMmon image is executed, you must allow the system to boot ROMmon before
doing any additional resets or power cycling. If the ROMmon-executing process is interrupted, the stem
interprets this as a bootup failure of the new ROMmon image. The router reverts to the ReadOnly image.
Note
The ROMmon upgrade image is marked as invalid if it fails to boot. Do not reset the router when it is
performing an initial bootup.
