Blade components firmware
CMC firmware
For more information on the update sequence for M1000e chassis, see the CMC Firmware 5.0 Release Notes on support site.
Signed CMC Firmware Image
For M1000e CMC version 5.0 and later, the 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 the firmware image
is authenticated by CMC 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.
Signature verification can be performed on firmware versions 3.1 and later. For firmware downgrade to M1000e CMC versions
earlier than 3.1, first update the firmware to a M1000e CMC version that is greater than or equal to 3.1 but less than 5.0. After
this update, firmware downgrade to earlier, unsigned M1000e CMC versions can be performed. CMC versions 5.0 and above
carry the signature as part of the released image and also carry the signature files of CMC versions 3.10, 3.20, 3.21, 4.0, 4.10,
4.11, 4.30, 4.31, 4.45, and 4.5 only. Therefore, CMC firmware update is supported only for these firmware versions. For any
version other than these, first update to any of these versions, and then update to the required version.
Viewing Currently Installed Firmware Versions
You can view the currently installed firmware versions using the CMC Web interface or RACADM.
Viewing Currently Installed Firmware Versions Using CMC Web
Interface
In the CMC Web interface, go to any of the following pages to view the current firmware versions:
Chassis Overview > Update
Chassis Overview > Chassis Controller > Update
Chassis Overview > Server Overview > Update
Chassis Overview > I/O Module Overview > Update
Chassis Overview > iKVM > Update
The Firmware Update page displays the current version of the firmware for each listed component and allows you to update
the firmware to the latest revision.
If the chassis contains an earlier generation server whose iDRAC is in recovery mode or if CMC detects that iDRAC has
corrupted firmware, then the earlier generation iDRAC is also listed on the Firmware Update page.
Viewing Currently Installed Firmware Versions Using RACADM
To view the currently installed firmware versions using RACADM, use the getkvminfo subcommand. For more information, see
the Chassis Management Controller for Dell PowerEdge M1000e RACADM Command Line Reference Guide.
Updating CMC Firmware
You can update CMC firmware using Web interface or RACADM. The firmware update, by default, retains the current CMC
settings. During the update process, you can reset CMC configuration settings back to the factory default settings.
NOTE: To update firmware on CMC, you must have Chassis Configuration Administrator privilege.
