1. Download Dell Networking OS software image file from the iSupport page to the local (FTP or TFTP)
server. The published hash for that file is displayed next to the software image file on the iSupport
page.
2. Go on to the Dell Networking system and copy the software image to the flash drive, using the copy
command.
3. Run the verify {md5 | sha256} [ flash://]img-file [hash-value] command. For example, verify sha256
flash://FTOS-SE-9.5.0.0.bin
4. Compare the generated hash value to the expected hash value published on the iSupport page.
To validate the software image on the flash drive after the image has been transferred to the system, but
before the image has been installed, use the verify {md5 | sha256} [ flash://]img-file [hash-value]
command in EXEC mode.
