DRM to search for latest firmware updates, see Using Dell Repository Manager to Search for the Latest

Updates on the Dell Support Site on the Dell Tech Center. For information on saving the inventory file

that DRM uses as input to create the repositories, see Saving Chassis Inventory Report Using CMC Web

Interface Saving Chassis Inventory Report Using CMC Web Interface. It is recommended to update the

firmware for a M1000e chassis in the following order:

• 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.
