Interface Description
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 Chassis Management Controller Version 5.0 Release
Notes at dell.com/support/manuals.
Remote RACADM command
line interface
Use this command line utility to manage CMC and its components. You
can use remote or firmware 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 firmware 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 prefix.
Chassis LCD Panel Use the LCD on the front panel to:
• View alerts, CMC IP or MAC address, user programmable strings.
• Set DHCP
• Configure 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 configured.
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.
WS-MAN The LC-Remote Services is based on the WS-Management protocol to
do one-to-many systems management tasks. You must use WS-MAN
client such as WinRM client (Windows) or the Open WSMAN client
(Linux) to use the LC-Remote Services functionality. You can also use
Power Shell and Python to script to the WS-MAN 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 defines the semantics and
information types that can be modified in a managed system.
