152 Using the CMC Web Interface
To view firmware versions:
1
Log in to the Web interface (see "Accessing the CMC Web Interface" on
page 93).
2 Click Chassis in the system tree.
3 Click the Update tab. The Updatable Components page appears.
Updating Firmware
NOTE: To update firmware on the CMC, you must have Chassis Configuration
Administrator privilege.
NOTE: The firmware update retains the current CMC and iKVM settings.
NOTE: If a web user interface session is used to update system component
firmware, the "Idle Timeout" setting must be set high enough 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" on page 143.
NOTE: The iDRAC firmware is updatable through the iDRAC Web-based user
interface or remote RACADM. However, if the CMC user interface detects the
presence of a server but is unable to communicate with it, it indicates a corruption.
In such cases, iDRAC Firmware Update will be available from the Updatable
Components page. To open the Updatable Components page, select Chassis in the
system tree, and then click the Update tab.
The Updatable Components page displays the current version of the
firmware for each listed component and allows you to update the firmware to
the latest revision by uploading the firmware image file (package).
NOTE: Be sure you have the latest firmware version. You can download the latest
firmware image file from the Dell Support website.
Updating the CMC Firmware
NOTE: During updates of the CMC firmware or the iDRAC firmware on a server,
some or all of the fan units in the chassis will spin at 100%. This is normal.
NOTE: The Active (primary) CMC resets and becomes temporarily unavailable after
the firmware has been uploaded successfully. If a standby CMC is present, the
standby and active roles will swap; the standby (secondary) CMC becomes the
active (primary) CMC. If an update is applied only to the active (primary) CMC, after
the reset is complete the primary CMC will not be running the updated image, only
the standby (secondary) will have that image.
