You must perform the following steps in the sequence given below to upgrade and activate the firmware:

Procedure


Step 1

Update BIOS Firmware

Step 2

Activate BIOS

Step 3

Update and Activate other Firmwares using HUU ISO



Note


If the BIOS firmware is not upgraded before the HUU ISO upgrade, then the BIOS will not be loaded properly and the boot options will not be displayed.


Update BIOS Firmware

Procedure


Step 1

Check the BIOS check box and click Update.

Step 2

Click Install BIOS Firmware Through Browser Client and select the BIOS image.

Step 3

Click Install Firmware.

Step 4

Choose the BIOS version and click Activate Firmware.

Step 5

Choose Host Power > Power On after activating the BIOS.


Update and Activate other Firmwares using HUU ISO

Procedure


Step 1

In the Cisco Integrated Management Controller toolbar, click Launch vKVM to launch the KVM console.

Step 2

In the KVM console, choose Virtual Media > vKVM-Mapped vDVD.

Step 3

Click Browse and browse for the HUU .iso file.

Step 4

Step 8

Click Update & Activate.

Step 9

In the Update & Activate All window, check the Power Cycle to Activate check box and click Update & Activate.

Note

 

BIOS upgrade is skipped during this step because BIOS is already upgraded to the latest version (see Update BIOS Firmware and Activate BIOS).

Step 10

The system is restarted after the firmware upgrade. Log in back to verify the upgraded firmware versions.


Verify the Firmware Version

Choose Admin > Firmware Management and verify the upgraded firmware versions in the Running Version column.

Choose Chassis > Summary and verify the firmware versions.


Note


Rollback of BMC and BIOS is not recommended while upgrading using the HUU ISO because it might cause compatibility issues.
