Updating the CMC firmware

You can update the CMC firmware using web interface or RACADM. The firmware update, by default, retains the current CMC settings.
  • NOTE: To update firmware on CMC, you must have the Chassis Configuration Administrator privilege.
  • NOTE: You cannot update the CMC firmware if the firmware image file does not contain a verification signature or it contains a verification signature, which is not valid or corrupted.
  • NOTE: You cannot downgrade the CMC firmware to an earlier version if the computed signature of that earlier version is not recognized by the current CMC firmware.

If a Web user interface session is used to update system component firmware, the Idle Timeout ( 0, 60–10800) setting must be set to a higher value to accommodate the file transfer time. Sometimes, the firmware file transfer time may be as high as 30 minutes. To set the idle timeout value, see Configuring Services.

During CMC firmware updates, it is normal for some or all of the fan units in the chassis to rotate at 100% speed.

To avoid disconnecting other users during a reset, notify authorized users who may log in to CMC and check for active sessions on the Sessions page. To open the Sessions page, click Chassis Overview in the left pane, click Network, and then click the Sessions.

During the final phases of the firmware update process in CMC, the browser session and connection with CMC is lost temporarily as the CMC is not connected to the network. CMC generates the chassis overall health as critical owing to the temporary network loss. When CMC restarts after a few minutes, log in to it. The CMC then generates the chassis overall health as healthy and the CMC network link is up. After CMC resets, the new firmware version is displayed on the Firmware Update page.

When transferring files to and from CMC, the file transfer icon spins during the transfer. If your icon is not animated, make sure that your browser is configured to allow animations. For more information about allowing animations in the browser, see Allow Animations in Internet Explorer .

  • NOTE: In a chassis supported by 2400W AC PSUs, if you attempt to update/downgrade the firmware with a version which the 2400W AC PSUs do not support, an error message is displayed. The 2400W AC PSUs support CMC 1.40-A00 and later images.
  • NOTE: If you have configured the slot name length to more than 15 characters in the current version of CMC, downgrading the CMC firmware truncates the slot name length to 15 characters.
