Users Guide
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 rmware includes a signature. The CMC rmware performs a signature verication step
to ensure the authenticity of the uploaded rmware. The rmware update process is successful only if the rmware image is
authenticated by CMC to be a valid image from the service provider and has not been altered. The rmware update process is
stopped if CMC cannot verify the signature of the uploaded rmware image. A warning event is then logged and an appropriate error
message is displayed.
Signature verication can be performed on rmware versions 3.1 and later. For rmware downgrade to M1000e CMC versions earlier
than 3.1, rst update the rmware to a M1000e CMC version that is greater than or equal to 3.1 but less than 5.0. After this update,
rmware 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 les 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 rmware update is supported only for these rmware versions. For any version other than these, rst update
to any of these versions, and then update to the required version.
Viewing Currently Installed Firmware Versions
You can view the currently installed rmware 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 rmware 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 rmware for each listed component and allows you to update the
rmware 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
rmware, 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 rmware 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 rmware using Web interface or RACADM. The rmware update, by default, retains the current CMC settings.
During the update process, you can reset CMC conguration settings back to the factory default settings.
NOTE: To update rmware on CMC, you must have Chassis Conguration Administrator privilege.
If a Web user interface session is used to update system component rmware, the Idle Timeout setting must be set high enough to
accommodate the le transfer time. In some cases, the rmware le transfer time may be as high as 30 minutes. To set the Idle
Timeout value, see Conguring Services.
During updates of CMC rmware, it is normal for some or all of the fan units in the chassis to spin at 100%.
If you have redundant CMCs installed in the chassis, it is recommended to update both the CMCs to the same rmware version at
the same time with a single operation. If CMCs have dierent rmware and a failover occurs, unexpected results may occur.
