RACADM CLI
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, it requires CMC IP, username and password.
To use remote RACADM from your management station, install remote RACADM using the Dell Systems
Management Tools and Documentation DVD that is available with your system. For more information on Remote
RACADM
Web Interface Provides remote access to CMC using a graphical user interface. The Web interface is built into the CMC
rmware and is accessed through the NIC interface from a supported web browser on the management station.
For a list of supported Web browsers, see the Supported Browsers section in the Dell System Software Support
Matrix at dell.com/support/manuals.
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.
SNMP Simple Network Management Protocol (SNMP) is a set of protocol denitions for managing devices on the
networks. The CMC provides access to SNMP, which allows you to use SNMP tools to query the CMC for
Systems Management information. The CMC MIB le can be downloaded from the CMC Web interface, go to
Chassis Overview → Network → Services → SNMP. See the Dell OpenManage SNMP Reference Guide for
more information about the CMC MIB.
The following example show how the net-snmp snmpget command can be used to get the chassis service
tag from the CMC.
snmpget -v 1 -c <CMC community name> <CMC IP address>.

WSMan The WSMan Services is based on the Web Services for Management (WSMan) protocol to perform one-to-
many systems management tasks. You can use WSMan client such as WinRM client (Windows) or the
OpenWSMan client (Linux) to use the LC-Remote Services functionality. You can also use Power Shell and
Python script the WSMan interface.
WSMan 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 denes the semantics and information types that can be
modied 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 proles and extension proles.
NOTE: The SSL port used for transport security is the same as the CMC HTTPS port.
