Cisco Host Upgrade
Utility (hereafter referred to as HUU) is a
tool that you can use to upgrade the firmware on a Cisco UCS C-Series server.
HUU includes an option that enables you to download a container for a selected
platform on a Windows operating system. You can download the container from the
HUU ISO by burning the ISO on a physical media. When you insert the physical
media into the server, auto-run launches an Index.html page in your browser.
This index.html page provides access to the location from where you can
download the container. You also can download the container from the ISO using
the standard ISO extraction utilities.
HUU provides a user
interface where you can choose the firmware components that need an upgrade. In
the previous releases (1.4(x)), HUU provided a text menu from which you could
choose the components and initiate the upgrade. From version 1.5(x) onwards,
HUU provides a graphical user interface to accomplish this task.
You can upgrade the
firmware on the following components using HUU:

firmware for a particular server, HUU discovers and displays only the
components supported by that server.
