Updating the BIOS and Cisco IMC Firmware
Caution When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same
version or the server will not boot. Do not power off the server until the BIOS and Cisco IMC firmware
are matching or the server will not boot.
Cisco provides the Cisco Host Upgrade Utility to assist with simultaneously upgrading the BIOS, Cisco
IMC, and other firmware to compatible levels.
The server uses firmware obtained from and certified by Cisco. Cisco provides release notes with each
firmware image. There are several methods for updating the firmware:
Recommended method: Use the Cisco Host Upgrade Utility to simultaneously upgrade the Cisco
IMC, BIOS, LOM, LSI storage controller, and Cisco UCS P81E VIC firmware to compatible levels.
See the Cisco Host Upgrade Utility Quick Reference Guide for your firmware level at the
documentation roadmap link below.
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 below to update the BIOS and
Cisco IMC 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 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.
