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 denitions 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 CMC 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 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.
NOTE: The SSL port used for transport security is the same as the CMC HTTPS port.
