The IMM2 also provides the following remote server management capabilities through the ipmitool
management utility program:
• Command-line interface (IPMI Shell)
The command-line interface provides direct access to server management functions through the IPMI 2.0
protocol. Use the command-line interface to issue commands to control the server power, view system
information, and identify the server. You can also save one or more commands as a text file and run the
file as a script.
• Serial over LAN
Establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely
view and change the UEFI settings, restart the server, identify the server, and perform other management
functions. Any standard Telnet client application can access the SOL connection.
