Installing the Server OS
This chapter includes the following sections:
- OS Installation Methods
- KVM Console
- PXE Installation Servers
- Booting an Operating System from a USB Port
OS Installation Methods
C-Series servers support several operating systems. Regardless of the OS being installed, you can install it on your server using one of the following tools:
KVM Console
The KVM console is an interface accessible from Cisco IMC that emulates a direct keyboard, video, and mouse (KVM) connection to the server. The KVM console allows you to connect to the server from a remote location.
Instead of using CD/DVD or floppy drives physically connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives. You can map any of the following to a virtual drive:
-
CD/DVD or floppy drive on your computer
-
Disk image files (ISO or IMG files) on your computer
-
USB flash drive on your computer
-
CD/DVD or floppy drive on the network
-
Disk image files (ISO or IMG files) on the network
-
USB flash drive on the network
You can use the KVM console to install an OS on the server.
Note | To configure the KVM console successfully for the Cisco UCS C3260 server, you need to configure IP addresses for the Cisco IMC, CMC, and BMC components. You can configure the IP addresses for these components using the CLI interface or Web UI. For the CLI, use the command scope network, or view the setting using scope <chassis/server1/2><cmc/bmc><network>. To configure IP addresses for network components on the web interface, see the steps described in the section Configuring Network-Related Settings. |
Note | The KVM Console is operated only through the GUI. To launch the KVM Console, see the instructions in the Cisco UCS C-Series Servers Integrated Management Controller GUI Configuration Guide. |
Installing an OS Using the KVM Console
Because the KVM console is operated only through the GUI, you cannot install a server OS using the CLI. To install an OS using the KVM console, follow the instructions in the "Installing an OS Using the KVM Console" section of the Cisco UCS C-Series Servers Integrated Management Controller GUI Configuration Guide.

PXE Installation Servers
A Preboot Execution Environment (PXE) installation server allows a client to boot and install an OS from a remote location. To use this method, a PXE environment must be configured and available on your VLAN, typically a dedicated provisioning VLAN. Additionally, the server must be set to boot from the network. When the server boots, it sends a PXE request across the network. The PXE installation server acknowledges the request, and starts a sequence of events that installs the OS on the server.
PXE servers can use installation disks, disk images, or scripts to install an OS. Proprietary disk images can also be used to install an OS, additional components, or applications.
Note | PXE installation is an efficient method for installing an OS on a large number of servers. However, considering that this method requires setting up a PXE environment, it might be easier to use another installation method. |

What to Do Next
After the OS installation is complete, reset the LAN boot order to its original setting.
Booting an Operating System from a USB Port
All Cisco UCS C-series servers support booting an operating system from any USB port on the server. However, there are a few guidelines that you must keep in mind, prior to booting an OS from a USB port.
-
To maintain the boot order configuration, it is recommended that you use an internal USB port for booting an OS.
-
The USB port must be enabled prior to booting an OS from it.
By default, the USB ports are enabled. If you have disabled a USB port, you must enable it prior to booting an OS from it. For information on enabling a disabled USB ports, see topic Enabling or Disabling the Internal USB Port in the server-specific installation and service guide available at the following link:
http://www.cisco.com/en/US/products/ps10493/prod_installation_guides_list.html.
-
After you boot the OS from the USB port, you must set the second-level boot order so that the server boots from that USB source every time.
