Terminal Mode
The Terminal Mode feature allows you to directly interface to the server’s Baseboard
Management Controller via a serial port connection and execute text-based commands. Two
types of text commands are supported:
• A limited selection of text commands
• Standard binary IPMI 1.5 hex-ASCII commands
Using the terminal mode feature you can do the following:
• Power the server on or off
• Reset the server
• Retrieve the server’s health status
• Configure and retrieve the server management subsystems boot options
• Configure and retrieve the BMC’s terminal mode configuration
• Execute any platform supported binary command specified in the IPMI v1.5 specification
using the hex-ASCII format
See Terminal Mode Configuration on page 79 for details about the terminal mode configuration
screen.
Setup and Configuration
Connection Mechanism
Two types of connection mechanisms are supported as follows:
• Direct connection, where a local host is connected to the target system directly
• Modem connection, where the local host is connected to the target system via a modem
Hardware Setup
Hardware setup is dependent upon the type of connection mechanism being employed as
follows:
• For a direct connection, a null modem cable is needed to connect the local host to the target
system
• For a modem connection, the local host and target systems must both be connected to
modems via serial cables
Configuration Using System Maintenance Utility (SMU)
Configuration of terminal mode requires proper configuration of the following:
• The serial channel
• User login information (user name and password)
• The terminal mode configuration parameters
The SMU provides methods to access and manipulate all the necessary parameters for terminal
mode configuration.
