3.3.2. Connecting IPMI option
IPMI Version 1.5 defines a serial connection to access certain system parameters and to perform
system actions like powering down the system or performing a hard reset. Modern server systems,
supporting the IPMI V1.5 specification, provide a modus where the externally available COM2
serial connection can be configured as system management port (sometimes also referred to as
emergency management port ). LARA may connect to this port in order to enable remote system
management operations.
At http://developer.intel.com/design/servers/ipmi/index.htm You will find further information
about IPMI 1.5.
In order to use the IPMI over serial interface it has to be enabled in the host system. This can
be done using BIOS settings or special utilities provided by the server manufacturer. Refer to the
server manufacturer’s manual site to find out how the IPMI over serial line can be enabled and
configured and where the IPMI serial port is placed.
Hint:
IPMI V1.5 is only supported by modern server systems. No server system manufactured before
2002 supports IPMI 1.5. By the date of printing this manual only the Intel SDS2 server main
board has a proper support of IPMI Verson 1.5.
Connect the IPMI option serial cable to the RS232 port 1 on the rear side of LARA and to the
serial port of the controlled system.
