52 Installing and Setting Up CMC
Accessing CMC Through a Network
After you have configured CMC network settings, you can remotely access
CMC using various interfaces. Table 2-1 lists the interfaces that you can use
to remotely access CMC.
NOTE: Since telnet is not as secure as the other interfaces, it is disabled by default.
Enable Telnet using web, ssh, or remote RACADM.
NOTE: CMC default user name is root and the default password is calvin.
You can access CMC and iDRAC Web interfaces through the CMC Network
Interface using a supported Web browser; you can also launch them from the
Dell Server Administrator or Dell OpenManage IT Assistant.
Table 2-1. CMC Interfaces
Interface Description
Web interface Provides remote access to 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 at
support.dell.com/manuals.
Remote RACADM
command line
interface
Provides remote access to CMC from a management station
using a command line interface (CLI). Remote RACADM uses
the racadm -r option with CMC’s IP address to execute
commands on CMC.
For more information on remote racadm, see "Accessing
RACADM Remotely" on page 81 and subsequent sections.
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 an insecure 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.
