FPGA Recovery Upgrade on the NSE-150

Minimal boot mode is entered on the NSE-150 if an in-progress FPGA upgrade is abruptly stopped (due
to various factors such as a power outage, router crash, hardware OIR, or other reason).
In minimal boot mode, the Fast Ethernet management port (interface fastethernet 0) is the only working
port on the NSE-150.
If minimal boot mode is entered when using a Cisco 7304 with an NSE-150 because an FPGA upgrade
was interrupted, simply retry the upgrade in minimal boot mode using the upgrade fpga all command.
After upgrading the FPGA, the router can be booted using a Cisco IOS image on one of the Flash file
systems on the router or from another source.

Upgrading ROMmon

Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image
instead of having to replace hardware (NSE) to get a new image.
There are three ROMmon images: one "golden"—always there (ROM 0—one-time programmable) and
two others that you can configure the system to point to (ROM 1 and ROM 2). At bootup, the system
starts with the golden image and then jumps to the one to which you have pointed the system. If a new
ROMmon image you are pointing to fails to boot up Cisco IOS for the first time, then the router marks
this ROMmon image as invalid and will revert to the golden image after a subsequent reset or power
cycling.
After you have downloaded a new ROMmon image to the rewriteable ROMmon, you need to do a reload
of Cisco IOS (recommended) for the new ROMmon to take effect. This is required only for the new
ROMmon to take effect; it is not required otherwise.
The first time a new ROMmon image is loaded, you must allow the system to boot up Cisco IOS before
doing any additional resets or power cycling. If the ROMmon loading process is interrupted, the system
interprets this as a bootup failure of the new ROMmon image. The router reverts the ROMmon back to
the golden image in ROM 0.
Images are marked as invalid if the first Cisco IOS bootup is not completed. Do not reset the router when
Note
it is doing an initial bootup.

Using the show rom-monitor Command

Use the show rom-monitor command to determine which ROMmon images are available. See the
following example for information shown in the output of the show rom-monitor command:
