5.12 Serial Over LAN
Serial over LAN (SOL) enables suitably designed blades and servers to transparently redirect a
serial character stream of a baseboard UART to/from a remote client via LAN over RMCP+
sessions. This enables users at remote consoles to access the serial port of a blade/server and
interact with a text-based BIOS console, operating system, command line interfaces, and serial
text-based applications.
The IPMC provides a dedicated sideband connection to the Base Interface Ethernet controller.
This connectivity is not shared with IPMB-0 or any other I2C/SMBus/IPMB connections that the
IPMC may use on the Blade for hardware management. Data from the payload serial
redirection is routed thru the sideband connection to the Base I/F. Vice versa the Ethernet
controller filters packets based on either MAC address, RMCP port number, or IP address and
forwards them to the serial redirection over the sideband interface.
Client software like openIPMI is required to enable SOL and to communicate with the SOL
based serial console.
5.13 Control Logic
The blade provides control logic for specific functions including:
 Payload power supervision and sequencing
 Payload resets
 Multiple HW interfaces between payload and IPMC
 Support for sensors as required
Any control circuitry based on programmable logic whether intended for payload supervision
or as part of the payload is remotely upgradeable. Crisis recovery circuitry is provided to
prevent board lock-ups as the result of a failed remote upgrade of the board control logic.
5.14 Front Board Face Plate
The blade's face plate provides the following interfaces and control elements:
 Two USB 2.0 ports
 Two 10/1000/1000Base-T Ethernet ports
