• Chassis Overview → Chassis Controller → Update• Chassis Overview → Server Overview → Server Component UpdateThe Firmware Update page displays the current version of the firmware for each listed component and allows you to update thefirmware to the latest version.If the chassis contains an earlier generation server, whose iDRAC is in recovery mode or if CMC detects that iDRAC has corruptedfirmware, then the earlier generation iDRAC is also listed on the Firmware Update page.Viewing currently installed firmware versions using RACADMYou can view the currently installed firmware versions using racadm getversion command. For more information about otherRACADM commands, see the Dell Chassis Management Controller for PowerEdge FX2/FX2s RACADM Command Line ReferenceGuide.Updating the CMC firmwareYou can update the CMC firmware using web interface or RACADM. The firmware update, by default, retains the current CMCsettings.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 itcontains 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 isnot 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 setto a higher value to accommodate the file transfer time. In some cases, 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 onthe Sessions page. To open the Sessions page, click Chassis Overview in the left pane, click Network, and then click the Sessions.When transferring files to and from CMC, the file transfer icon spins during the transfer. If your icon is not animated, make sure thatyour browser is configured to allow animations. For more information about allowing animations in the browser, see Allow Animationsin Internet Explorer.NOTE: In a chassis supported by 2400W AC PSUs, if you attempt to update/downgrade the firmware with a version thatis not supported by 2400W AC PSUs, an error message is displayed. The 2400W AC PSUs support CMC 1.40-A00 andlater images.Updating CMC firmware using web interfaceTo update the CMC firmware using the CMC web interface:1.
