Remote RACADM command line
interface
Use this command line utility to manage CMC and its components. You can use remote or
rmware RACADM:
• Remote RACADM is a client utility that runs on a management station. It uses the out-of-
band network interface to run RACADM commands on the managed system and uses the
HTTPs channel. The –r option runs the RACADM command over a network.
• Firmware RACADM is accessible by logging in to CMC using SSH or telnet. You can run the
rmware RACADM commands without specifying the CMC IP, user name, or password.
After you enter the RACADM prompt, you can directly run the commands without the
racadm prex.
Chassis LCD Panel Use the LCD on the front panel to:
• View alerts, CMC IP or MAC address, user programmable strings.
• Set DHCP
• Congure CMC static IP settings.
• View CMC MAC address for the active CMC.
• View the CMC VLAN ID appended to the end of CMC IP, if the VLAN is already congured.
Telnet Provides command line access to CMC through the network. The RACADM command line
interface and the connect command, which is used to connect to the serial console of a server
or IO module, are available from the CMC command line.
NOTE: Telnet is not a secure protocol and is disabled by default. Telnet transmits all
data, including passwords in plain text. When transmitting sensitive information, use
the SSH interface.
SSH Use SSH to run RACADM commands. It provides the same capabilities as the Telnet console
using an encrypted transport layer for higher security. The SSH service is enabled by default on
CMC and can be disabled.
WSMan The CMC Services is based on the WS-Management protocol to do one-to-many systems
management tasks. You must use WSMan client such as WinRM client (Windows) or the Open
WSMan client (Linux) to use the CMC Services functionality. You can also use Power Shell and
Python to script to the WSMan interface.
Web Services for Management (WS-Management) is a Simple Object Access Protocol
(SOAP)–based protocol used for systems management. CMC uses WS–Management to
convey Distributed Management Task Force (DMTF) Common Information Model (CIM)–based
management information. The CIM information denes the semantics and information types
that can be modied in a managed system.
The CMC WSMan implementation uses SSL on port 443 for transport security, and supports
basic authentication. The data available through WS-Management is provided by CMC
instrumentation interface mapped to the DMTF proles and extension proles.
For more information, see the following:

• DTMF Web site — dmtf.org/standards/proles/
• WSMan release notes or Read Me le.

Web services interfaces can be utilized by leveraging client infrastructure, such as Windows
WinRM and Powershell CLI, open source utilities like WSManCLI, and application programming
environments like Microsoft .NET.
