DIAG OS installation or update
Load or update the DIAG-OS—the diag installer image—using the onie-nos-install command. The DIAG-OS installer runs
in two modes: Update mode or Install mode.
● In Update mode, the DIAG-OS updates the existing DIAG-OS and boots back to ONIE.
● In Install mode, the DIAG-OS erases the existing DIAG-OS and loads the new DIAG-OS.
NOTE: If you have a recovery USB plugged into your system, remove it before using the onie-nos-install command.
NOTE: Before you begin, go to www.dell.com/support and download the diagnostic package.
1. Enter the onie-discovery-stop command to stop ONIE Discovery mode.
2. Assign an IP address to the management interface and verify the network connectivity.

3. Upgrade the DIAG Installer.
NOTE:
In Install mode, the DIAG-OS installation removes any existing NOS and DIAG-OS partition. If you do not create
file /tmp/diag_os_install_mode, the DIAG-OS installs in Upgrade mode. In this case, the installation process
does NOT touch any existing NOS.
NOTE: The Z9432F-ON switch has the Secure Boot feature. For this feature only, the .bin file is replaced with
the .tar file. The .tar archive file has both the .bin file and the .sig file to verify the secure boot .bin file. You
do not have to untar the .tar file to access the .bin file. If you specify the .bin file, the .sig file MUST be in the
same location as the .bin file.
