This support document provides an overview for the steps required to
set up CIMC network connectivity for the UCS C-Series server.
Cisco recommends that you:
Have a working knowledge of the Cisco UCS C-Series Server Blade
hardware and software administration.
Be familiar with UCS C-Series Servers Cisco Integrated Management
Understand the impact and implications of the different commands
described in this document.
Be familiar with the UCS C-Series components and
The information in this document is based on Cisco UCS C-Series
The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a default configuration. If your network is live, make sure that you understand
the potential impact of any command.

This is an overview of how to setup CIMC network connectivity for UCS
Overview of KVM features:
Cisco C-Series Rack Servers provides a physical local video and two
usb connections for a usb keyboard, video monitor, and usb mouse connection
through the front panel of the Rack Server using the Cisco provided dongle
All Rack Servers can have up to 4 active KVM over IP sessions in
addition to the local connection at front or rear panels. All active sessions
have full control of the console
KVM over IP supports text and graphics modes of the graphics
controller and needs no manual setting to view data
Graphics modes supported are up to the video chips maximum
capabilities of 1600 x 1200 with 16 bit color.
KVM sessions over Linux may, depending on Linux distribution, require
If KVM responsiveness seems slow; many factors such as network
bandwidth latency can effect this. Reducing the color depth and resolution can
improves the responsiveness.
Remote KVM shows exactly what is on the video. This is not a “serial
terminal” view but rather a pixel by pixel rendition
If recording the session is desired you can use utilities on the
local client such as webex or other screen capture
If text logging of keystrokes is desired use SOL (Serial Over Lan)
features and a terminal program to capture the text.

Complete these steps in order to power up the server:
Plug the power cord into the chassis.
CIMC initializes system standby (Power Off
CIMC is active and can be controlled through GUI or CLI, if you
know the IP address.
Depress Front Panel Power:
The Fans begins to spin up.
Then POST sequence begins.
At this point you can either boot up or begin the installation
Note that for large memory, models can display a blank screen for
For C-250—If you immediately depress the power switch, you
interrupt the CIMC initialization.
It is possible that the Fans spin down and the indicator turns
If this happens, wait and then press the power button again.
While the server boots up, you can access BIOS, Cisco Splash Screen in
Press ESC in order to watch POST.
Once the system begins to boot, press F2 in order to access the BIOS
configuration screen. These steps require a physical KVM, either directly
attached monitor and keyboard, or a local/remote KVM. Once the chassis boots,
press F2 in order to get to this screen.
Press F6 in order to manually choose the boot
Press F12 for the network boot.
While in BIOS you can press F8 for the CIMC IP address configuration
and password reset.
Choose either DHCP or Static config.
Enter the VLAN tag if needed.
Enter the CIMC password.
After you make a change to IP or enable DHCP, you can press F5 in
order to display the configured IP.
Press F10 in order to save the configuration.
Complete these steps:
The POST and the option ROM config is displayed during the boot up
These are the Option ROM config screens, which are
HBA/CNA if installed
Then point a Web browser to the configured CIMC IP address.
Choose Admin > Network Settings and check
In order to revert to DHCP, from the Admin tab in the GUI, choose
Network and in IPv4 properties, check the Use
DHCP box. Reboot the chassis.
Monitor your DHCP server to see when the IP is assigned to your
MAC. Then point to the new IP server.
Once you logged into the CIMC, you can check the network
