● 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 <username> -p <password> sel get
NOTE: The default iDRAC user name and password are provided on the system badge.
● 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. You need to logout from
the IPMI terminal using [sys pwd -x], below are the example for IPMI Terminal mode commands.
