Signed CMC firmware image
The CMC firmware includes a signature. The CMC firmware performs a signature verification step to ensure the authenticity of the
uploaded firmware. The firmware update process is successful only if CMC authenticates the firmware image to be a valid image
from the service provider and has not been altered. The firmware update process is stopped if CMC cannot verify the signature of
the uploaded firmware image. A warning event is then logged and an appropriate error message is displayed. The firmware update
includes upgrade and downgrade.
Downloading CMC firmware
Before beginning the firmware update, download the latest firmware version from support.dell.com, and save it to your local
