Architectural Components
IPMC
As shown in the block diagram in
UART interface to the blade’s serial port (COM1). This interface is used by the IPMC
firmware to write data to the blade’s serial port or to receive the blade’s serial port data
written by the EFI BIOS or the operating system. The serial port may be connected to
either to the IPMI controller or to RJ-45 connector(s) on the front panel and the RTM (if
available). The switching of the serial port between front-panel/RTM and the IPMC’s
UART port is controlled by the IPMC firmware.
The IPMC also provides a dedicated SMBus connection to the Ethernet controller, whose
ports are connected to the base Ethernet interface.
The KCS interface is used for interaction between the IPMC firmware and software
executing on the OS (for example, OpenIPMI or OpenHPI) by sending/receiving IPMI
messages, and does not play a role during SOL communication. The KCS interface
however, may be used for SOL-related IPMC configuration, as described below.
Ethernet Controller
The Ethernet controller provides an advanced pass-through mode of operation where
the controller allows the on-board IPMC to communicate over the Ethernet ports using
a sideband interface port.
The Ethernet controller embedded in ICH is available with standby (management)
power, so that it is possible to view the initial serial port data written by the EFI BIOS
or the OS.
Theory of Operation
Front Panel Serial Port or RTM
By default, the serial console is connected to the serial port connector(s) on the front
panel and RTM (if available).
If serial cables are connected to both the front panel and RTM connectors, both
connections will be active. However, only one user is allowed to use the serial session.
Serial Over LAN
IPMC firmware is pre-configured at manufacturing time with default serial port settings
(baud rate, parity bits, data bits, stop bits, flow control), user name and password for
RMCP+ sessions. The SOL feature, however, is disabled by default.
The IP address to be used by IPMC can be configured during initial setup of the blade in
the system.
• Client software running on any remote node that has LAN access to the blade
whose serial port data is to be accessed. The IPMC is responsible for controlling the
serial hardware MUX, the transformation of serial data to and from network
packets, and the transmission and reception of SOL network packets through the
Ethernet controller sideband interface port.
