44 Installing and Setting Up the CMC
Accessing the CMC Through a Network
After you have configured the CMC network settings, you can remotely
access the CMC using any of the following interfaces:
•Web interface
•Telnet console
•SSH
• Remote RACADM
Telnet is enabled via one of the other interfaces; telnet is not as secure as the
other interfaces so it is disabled by default.
Table 2-1 describes each CMC network interface.
NOTE: The CMC default user name is root and the default password is calvin.
Table 2-1. CMC Interfaces
Interface Description
Web interface Provides remote access to the CMC using a graphical user
interface. The Web interface is built into the CMC firmware 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 on the
Dell Support website at support.dell.com/manuals.
Remote RACADM
command line
interface
Provides remote access to the CMC from a management station
using a command line interface (CLI). Remote RACADM uses
the racadm -r option with the CMC’s IP address to execute
commands on the CMC.
Telnet Provides command line access to the 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 an unsecure protocol that transmits all data—
including passwords—in plain text. When transmitting sensitive
information, use the SSH interface.
SSH Provides the same capabilities as Telnet using an encrypted
transport layer for greater security.
