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

• CMC firmware

• Chassis infrastructure firmware

Viewing currently installed firmware versions

You can view the currently installed firmware versions using the CMC web interface or RACADM.
