Overview of Firmware
C-Series servers use Cisco-certified firmware that is 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.
Note |
If you choose to update the firmware of individual components, you must first update and activate the CMC firmware to the version that you want to update the individual component. |
Caution |
When you install the new BIOS firmware, it must be from the same software release as the firmware that is running on the server. Do not install the new BIOS firmware until after you have activated the matching 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, , 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 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 want to update the firmware manually, you must update the firmware first. The firmware update process is divided into the following stages to minimize the amount of time that the server is offline:
-
Installation—During this stage, installs the selected firmware in the nonactive, or backup, slot on the server.
-
Activation—During this stage, sets the nonactive firmware version as active, causing a disruption in service. When the server reboots, the firmware in the new active slot becomes the running version.
After you activate the firmware, you can update the BIOS firmware.
