Lenovo Flex System x220, Installation And Service Manual

192.168.70.100 for the chassis and 192.168.70.10x for the compute node. For example, bay 1 in the
compute node is 192.168.70.101, bay 2 in the compute node is 192.168.70.102, and so forth.
• You can also assign IP addresses through the CMM ifconfig command. For
more information about the CMM ifconfig command, see the "Flex System
Chassis Management Module: Command-Line Interface Reference Guide" at
http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/com.lenovo.acc.cmm.doc/cli_command_
ifconfig.html. To change the IP address and configuration method, complete the following steps:
1. From the CMM web interface, click Chassis Management .
2. Click Component IP Configuration .
3. Click the device name.
4. Click the IPv4 or IPv6 tab.
• The IMM2 user ID and password are provisioned through the CMM. Use the login account of the CMM
to log in to the IMM2 web interface.
• If the CMM and compute nodes are set to use DHCP, and the CMM loses connectivity to the network, the
CMM attempts to acquire a new IP address when network connectivity is restored. The compute nodes
will not attempt to acquire an IP address again, and the compute nodes continue to use their existing
IP addresses. Therefore, if you experience network problems on compute nodes after connectivity
between the CMM and the network has been restored, you might have to reset the system-management
processor on each of the compute nodes in the chassis (including Flex System Manager management
software, if it is installed).
• You must set the CMM to use the Secure security policy for the IMM2 to power on the compute node
and for the IMM2 to function properly. See “Secure security policy” in the Lenovo Flex System Chassis
Management Module Installation Guide .
To log in to the IMM2 web interface, complete the following steps:
1. Open a web browser and in the Address or URL field, type the IP address or host name of the IMM2 to
which you want to connect.
2. On the Login page, type the CMM user name and CMM password. You are then directed to the main
page of the IMM2 web interface. If you are using the IMM2 for the first time, you can obtain the user
name and password from your system administrator. All login attempts are documented in the IMM
event log.
3. Click IMM Management > User > Global Login Settings > General to modify the timeout value.
The IMM2 will log you out of the web interface if your browser is inactive for the number of minutes
that you have specified for the timeout period
IMM2 action descriptions
Navigate to activities you perform with the IMM at the top of the IMM window. The title bar identifies the user
name that is logged in, allows you to configure
Settings for the status screen refresh rate and a custom
trespass message, and Log out of the IMM web interface. Beneath the title bar are tabs that allow you to
access various IMM2 functions, as listed in Table 4 “IMM2 actions” on page 50.
