Overview of Firmware

C-Series servers use Cisco-certified firmware specific to the C-Series server model that you are using. You can download new releases of the firmware for all supported server models from Cisco.com.

Caution When you install new BIOS firmware, it must be from the same software release as the CIMC firmware running on the server. Do not install new BIOS firmware until after you have activated the matching CIMC firmware or the server will not boot.

To avoid potential problems, we strongly recommend that you use the Cisco Host Upgrade Utility (HUU), which upgrades the BIOS, CIMC, and other firmware to compatible levels. For detailed information about this utility, see the Cisco Host Upgrade Utility Guide for the version of the HUU that goes with the CIMC software release that you want to install. The HUU guides are available at the following URL: http:// www.cisco.com/en/US/products/ps10493/products_user_guide_list.html.

If you elect to update the firmware manually, you must update the CIMC firmware first. The CIMC firmware update process is divided into the following stages to minimize the amount of time the server will be offline:

•Installation. During this stage, CIMC installs the selected CIMC firmware in the non-active, or backup, slot on the server.

•Activation. During this stage, CIMC sets the non-active firmware version as active and reboots the server, causing a disruption in service. When the server reboots, the firmware in the new active slot becomes the running version.
