Updating the BIOS and Cisco IMC Firmware
When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same version
or the server does not boot. Do not power off the server until the BIOS and Cisco IMC firmware are matching
or the server does not boot.
Cisco provides the Cisco Host Upgrade Utility to assist with simultaneously upgrading the BIOS, Cisco IMC,
and other firmware to compatible levels.
Caution
The server uses firmware obtained from and certified by Cisco. Cisco provides release notes with each firmware
image. There are several possible methods for updating the firmware:
• Recommended method for firmware update: Use the Cisco Host Upgrade Utility to simultaneously
upgrade the Cisco IMC, BIOS, and component firmware to compatible levels.
See the Cisco Host Upgrade Utility Quick Refer ence Guide for your firmware release at the documentation
roadmap link below.
• You can upgrade the Cisco IMC and BIOS firmware by using the Cisco IMC GUI interface.
See the Cisco UCS C-Series Rack-Mount Server Configuration Guide.
• You can upgrade the Cisco IMC and BIOS firmware by using the Cisco IMC CLI interface.
See the Cisco UCS C-Series Rack-Mount Server CLI Configuration Guide.
