System BIOS and CIMC Firmware

This section includes information about the system BIOS and it includes the following topics:

•Updating the BIOS and CIMC Firmware, page 2-12

•Accessing the System BIOS, page 2-13

Updating the BIOS and CIMC Firmware

Caution When you upgrade the BIOS firmware, you must also upgrade the CIMC firmware to the same version or the server does not boot. Do not power off the server until the BIOS and CIMC firmware match or the server does not boot.

The server uses firmware that is obtained from and certified by Cisco. Cisco provides release notes with each firmware image. There are several methods for updating the firmware:

•Recommended method for systems running firmware level 1.2 or later—Use the Cisco Host Upgrade Utility to simultaneously upgrade the CIMC, BIOS, LOM, LSI storage controller, and Cisco UCS VIC firmware to compatible levels.

See the Cisco Host Upgrade Utility Quick Reference Guide for your firmware level at the documentation roadmap link that is listed in this section.

Note Your system firmware must be at minimum level 1.2 to use the Cisco Host Upgrade Utility. If your firmware is prior to level 1.2, you must use the methods listed in this section to update the BIOS and CIMC firmware individually.

•You can upgrade the BIOS using the EFI interface, or upgrade from a Windows or Linux platform.

See the Cisco UCS C-Series Rack-Mount Server BIOS Upgrade Guide.

•You can upgrade the CIMC firmware by using the CIMC GUI interface. See the Cisco UCS C-SeriesRack-Mount Server Configuration Guide.

•You can upgrade the CIMC firmware by using the CIMC CLI interface. See the Cisco UCS C-SeriesRack-Mount Server CLI Configuration Guide.
