Flash Memory and Switch Software
Flash memory on the MPX holds the Omni Switch/
Router’s executable images and configuration data for
each image file. When a switching module comes
online, the MPX downloads the appropriate image file
for that module to that module’s memory. Image files
(those with the .img extension) contain executable
code for different switching modules.
Not all image files loaded in flash memory are
required—only those that must be used with the
switching modules in your Omni Switch/Router. You
can remove any files that are not required for your
Omni Switch/Router configuration by using the
rm
command and free up space in flash memory. If you
need any switch files at a later date, you can use FTP
to back up the files to a PC before you delete them
from the switch.
The switch alters flash contents during execution when
a software command requests a configuration change,
when a remote administrator downloads a new execut-
able image, or when the switch fails and a record of
the failure is written to flash memory.
For detailed instructions on these procedures, refer to
your Omni Switch/Router User Manual and any manual
supplements that came with your Omni Switch/Router.
