a) Copy the file from a network location or local device plugged into the MIO/UMIO/MIO2 using the copy command.
[local]host_name# copy from_url to_url [-noconfirm]
b) Transfer the file to the /flash device using an FTP client with access to the system. The FTP client must be configured
to transfer the file using binary mode.
c) Transfer the file to the /flash device using an SFTP client with access to the system.
In release 20.0 and higher Trusted StarOS builds, FTP is not supported.
Step 4
Verify that the image file was successfully transferred to the /flash device by running the Exec mode the following
command:
[local]host_name# directory /flash
Step 5
Run the show version /flash/image_filename command to verify the build information.
Any CRC errors will be displayed in the output of this command. If any errors appear, check the build and re-transfer it
onto the chassis. Confirm that the correct image version and build description is displayed
