Users Guide

• IPMI basic mode — Supports a binary interface for program access, such as the IPMI shell (ipmish) that is included with the Baseboard
Management Utility (BMU). For example, to print the System Event Log using ipmish via IPMI Basic mode, run the following command:
ipmish -com 1 -baud 57600 -flow cts -u root -p calvin sel get
• IPMI terminal mode — Supports ASCII commands that are sent from a serial terminal. This mode supports limited number of
commands (including power control) and raw IPMI commands that are typed as hexadecimal ASCII characters. It allows you to view the
operating system boot sequences up to BIOS, when you login to iDRAC through SSH or Telnet.
