Chapter 4. Accessing the IMM2
Use this information to access the IMM2 remotely by using the command-line interface, Serial over LAN, or
web interface; or locally through the LAN over USB interface.
The IMM2 is a second generation hardware control device that provides enhanced systems-management
processor functions, video controller, and remote presence function in a single chip.
For more information about the IMM2, see http://publib.boulder.ibm.com/infocenter/
systemx/documentation/topic/ com.lenovo.sysx.imm2.doc/ printable_doc.html.
Accessing the IMM2 remotely
The IMM2 provides the following remote systems-management capabilities:
•
Command-line interface
The command-line interface provides direct access to systems-management functions through the IPMI
2.0 protocol. Use the command-line interface to issue commands to control the compute node power,
view system information, and identify the compute node. You can also save one or more commands as
a text file and run the file as a script.
For more information about the command-line interface, see http://publib.boulder.ibm.com/infocenter/
systemx/documentation/topic/ com.lenovo.sysx.imm2.doc/ printable_doc.html.
Note:
Remote IPMI and SNMP are disabled by default. To get IPMI access, create a local IMM user
account (separate from the CMM accounts). When this local account is created, the IPMI and SNMP
ports are automatically opened.
•
Secure Shell (SSH)
Use SSH to log into a remote compute node and execute commands.
•
Serial over LAN
Establish a Serial over LAN (SOL) connection to manage compute nodes from a remote location. You
can remotely view and change the UEFI settings, restart the compute node, identify the compute node,
and perform other management functions. Any standard Telnet client application can access the SOL
connection.
See your operating-system documentation for information about SOL commands that you can enter
by using the command-line interface.
•
Telnet
Use Telnet to log into a remote compute node and execute commands.
•
Web interface
Use the secure IMM2 web interface to perform systems-management activities within a web browser. For
information about accessing the web interface, see “Logging in to the IMM2 Web interface” on page 48.
Viewing the network access tag
Use this information to locate the IP address by viewing the network access tag, or by using the Setup
utility or systems-management software.
To access the web interface, you need the IP address of the IMM2. You can locate the IP address by viewing
the network access tag. The network access tag is attached to the front of the compute node. The front
