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 system.

It is recommended to follow the following update order while updating firmware for the chassis:

• Blade components firmware
