Parameters
The procedure in this section allows you to change the filename and IP
address of the emergency download parameters that are stored in
NVRAM. These values are used to retrieve a new image if the current
operational code on a module becomes corrupted. After the module
resets, the boot code detects that the operational code is corrupted and
automatically attempts to download a valid operational code image with
the stored filename and IP address. This image is not stored in permanent
memory. You must perform a normal download of this image at the EME
prompt to download this image into flash.
CAUTION: If you do not perform this normal download, the emergency
download repeats each time that the module resets until the maximum
number of module resets is reached.
This procedure is only required the first time that you upgrade a module
to software Release 3.0. From that point, any time that an image is
downloaded to the module, these parameters update automatically.
If the IP address of the file server that contains this file changes, or if the
directory where it is located changes, or if the actual filename changes,
you must use this procedure to update that information.
