Microcode - Cisco 7000 Series Hardware Installation And Maintenance Manual

If this initial diagnostic test fails, the system remains off line for another 15 seconds while it
performs a second set of diagnostic tests to determine whether or not the interface processor is faulty
and if normal system operation is possible.
If the second diagnostic test passes, which indicates that the system is operating normally and the
new interface processor is faulty, the system resumes normal operation but leaves the new interfaces
disabled. If the second diagnostic test fails, the system crashes, which usually indicates that the new
interface processor has created a problem in the bus and should be removed.
The system brings on line only interfaces that match the current configuration and were previously
configured as up; all other interfaces require that you configure them with the configure command.
On interface processors with multiple interfaces, only the interfaces that have already been
configured are brought on line.

Microcode

The Cisco 7000 series routers support downloadable microcode for most upgrades, which enables
you to load new microcode images into Flash memory instead of replacing the microcode ROMs on
the boards.The latest microcode version for each interface processor type is bundled with the system
software image. New microcode images are now distributed on floppy disk as part of a software
maintenance release; microcode upgrades are no longer distributed individually.
The default operation is to load the microcode from the bundled image. At system startup, an internal
system utility scans for compatibility problems between the installed interface processor types and
the bundled microcode images, then decompresses the images into running memory (RAM). The
bundled microcode images then function the same as images loaded from the individual microcode
ROMs on the processor modules. You can override the default and instruct the system to load a
specific microcode image from a Flash memory file or from the microcode ROM with the
microcode [card type] flash [file name] command.
Note
package. Overriding the bundle could possibly result in incompatibility between the various
interface processors in the system.
The show microcode command lists all of the microcode images that are bundled with the system
software image. In order to support OIR, the system loads a microcode image for all available
processor types.
Following is an example of the show microcode command:
