Options for Upgrading Firmware
You can use either the Cisco Host Upgrade Utility (HUU) to upgrade the firmware components or you can upgrade the firmware components manually.
-
HUU—We recommend that you use the HUU ISO file to upgrade all firmware components, which include the CIMC and BIOS firmware.
- Manual Upgrade—To manually upgrade the CIMC and BIOS firmware, you must first obtain the firmware from Cisco Systems, and then use the CIMC GUI or the CIMC CLI to upgrade it. After you upgrade the firmware, reboot the system.
