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.

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.
