Configuring CMC to Use Command Line Consoles 63
Using a Serial or Telnet Console
When you connect to the CMC command line, you are able to enter these
commands:
Connecting to Modules With the Connect
Command
While in a command line connection, the CMC supports the connect
command to establish a serial connection to server and IOM modules.
Connection to server modules is only provided for operating system
debugging. To connect to server modules to use operating system remote
consoles, you should use the iDRAC Web interface console redirection
feature or the iDRAC Serial Over LAN (SOL) functionality.
NOTICE: When executed from the CMC serial console, the connect -b option stays
connected until the CMC resets. This connection is a potential security risk.
NOTE: The connect command provides the –b (binary) option. The –b option
passes raw binary data, and cfgSerialConsoleQuitKey is not used. Additionally,
when connecting to a server using the CMC serial console, transitions in the DTR
signal (for example, if the serial cable is removed to connect a debugger) do not
cause a logout.
NOTE: If an IOM does not support console redirection, the connect command will
display an empty console. In that case, to return to the CMC console, type the
Escape sequence. The default console escape sequence is <Ctrl>\.
