Terminal Mode Commands
Terminal mode allows you to directly interface to the server's Baseboard Management Controller
(BMC) using 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 Intelligent Platform
Management Interface (IPMI) version 1.5 specification using the hex-ASCII format
NOTE:
Many of the Terminal Mode features described in this section require an extensive knowledge of
IPMI to use. It
is strongly recommended that Terminal Mode users have an advanced
understanding of IPMI before using the commands documented in this section.
Security Information
Access to the BMC using terminal mode is governed by the proper setup of user names and
password in the SMU. A session must be established with the BMC prior to accepting any terminal
mode commands. A limited selection of text commands and binary hex-ASCII commands that are
assigned the lowest IPMI privilege level are available prior to session establishment with the BMC.
See "Configuring Your Managed System with the System Maintenance Utility (SMU)" for more
information.
Since the terminal mode password is sent using clear text, it is highly desirable that the terminal
mode session takes place in a secure location over a secure link, preferably via a direct connection.
Connection via a modem is supported but not recommended.
Syntax
Terminal mode messages follow the general syntax below:
[<message data>]<newline sequence>
