The Lenovo Flex SystemChassis Management Module 2 (CMM) command-line interface (CLI) provides direct access to Flex System management functions as an alternative to using the web-based user interface.

The Lenovo Chassis Management Module 2 supports multiple Flex System chassis types. The CMM automatically detects the chassis type where it is installed. The CMM firmware adjusts the features and command options it supports based on its operating environment.

Using the CLI, you can issue commands to control the power and configuration of the CMM and other components that are in a Flex System chassis. The command-line interface also provides access to the text-console command prompt on each compute node through a Serial over LAN (SOL) connection.


You access the CMM CLI through a direct serial or Ethernet connection to the CMM, through a Telnet connection to the IP address of the CMM, or through a Secure Shell (SSH) connection to the CMM. You can initiate connections from the client system by using standard remote communication software; no special programs are required. You must authenticate with the CMM before you issue commands. You enter commands one at a time; however, you can use command scripting to enter multiple commands. The CLI does not support keyboard shortcuts, except for the special key sequence, Esc (, that terminates an SOL session.

Important: When interfacing with the CMM through an external script-based interface, observe the following restrictions to improve CMM reliability:
