Ethernet connection

Use these instructions to connect to the CMM through an Ethernet connection to use the CMM web interface.

Note: The HTTP connection is not available when the CMM security policy is set to secure (the factory default setting). When the security policy is set to secure, Ethernet connections must be made using HTTPS.

Complete the following steps:

  1. Connect an Ethernet cable from the client computer to the CMM by direct connection (Remote management and console connector) or through a network.
  2. To connect to the CMM for the first time, you might have to change the Internet Protocol properties on the client computer. Make sure that the subnet of the client computer is set to the same value as the CMM (the default CMM subnet is 255.255.255.0). The IP address of the CMM must also be in the same local domain as the client computer.
  3. Open a web browser on the client computer, and direct it to the CMM IP address. You must use a secure connection (https://).
    For the first connection to the CMM, use the default IP address of the CMM; if a new IP address has been assigned to the CMM, use that one instead.
    Note: The factory-defined static IPv4 IP address is 192.168.70.100, the default IPv4 subnet address is 255.255.255.0, and the default host name is MMxxxxxxxxxxxx, where xxxxxxxxxxxx is the burned-in MAC address. The MAC address is on a label on the CMM, below the IP reset button (see Lenovo Flex System Chassis Management Module CMM controls and indicators for the IP reset button location). See IPv6 addressing for initial connection for information about determining IPv6 addressing for initial connection.
  4. Enter the CMM user name and password to start the remote session.
    • The user ID and password are case sensitive. The same user ID and password are used for all methods of connecting to the CMM.
    • The default CMM user name is USERID, and the default password is PASSW0RD (note the number zero, not the letter O, in PASSW0RD).
    Note: Be sure to set the timeout value you want for your web session.
  5. If you are connecting to the Chassis Management Module for the first time, perform initial configuration of the CMM.
    Note: Do not restart the CMM using the initial configuration.
  6. Set the system-management processor (IMM/FSP) IP addresses for each of the compute nodes in the chassis, including the Flex System Manager management node, if one is installed. From the CMM user interface, select Chassis Management > Component IP configuration. Then select the device to change the IP address.
    Note:
    You must restart each device to show the new IP address.
  1. Cable the CMM to the management network and restart the CMM.
  2. Configure the Flex System Manager management node Ethernet ports, if a management node is installed:
    1. Use the console breakout cable to connect your client computer (or a keyboard, mouse, and monitor) to the KVM connector on the Flex System Manager management node, if one is installed. See Connecting to the management node locally by using the console breakout cable for more information.
    2. Start the Flex System Manager management node, if one is installed, and complete the initial setup.
      Note: If you are connecting to a single network for both data and management, configure management node Ethernet port Eth0 only during initial setup. If you are connecting to separate management and data networks, you must configure both management node Ethernet ports Eth0 and Eth1. Make sure that these ports point to networks that are on different subnets.
    3. After completing the management node Ethernet port configuration, you should be able to access the Flex System Manager user interface to complete the setup and begin managing chassis. On a computer connected to the management network, point your web browser to https://IP_address, where IP_address is the IP address that you entered during initial configuration.
  3. Log on to each of the I/O modules in the chassis and configure them.
