Be sure to calculate the amount of Flash Memory used by the User File System in the Flash
ROM. Use one of the following two commands to determine the amount of memory in use:
# df –k
or
# df
If the flash memory is full, you will no longer be able to save data to the Flash ROM. To free up
some memory, use the console cable to connect to the EM-1220-LX’s serial console terminal,
and then delete files from the Flash ROM.
