152 Intel NetStructure ® MPCBL0001 Technical Product Specification
Serial Over Lan (SOL)
Figure 29 is a block diagram of the SOL implementation on the blade:
This architecture requires the following three components to perform Serial over LAN operations.
1. SOL capable firmware executing on the Intelligent Platform Management Controller (IPMC).
The IPMC also provides a dedicated SMBus connection to base interface Ethernet controller.
This connectivity is not shared with IPMB-0 or any other I

C/SMBus/IPMB connections that
the IPMC may provide on the blade for hardware management.
2. Base interface Ethernet controller that provides a Total Cost of Ownership (TCO) sideband
interface to IPMC over which SOL traffic is redirected. The Ethernet controller also filters
packets based on either MAC address, RMCP port number, or IP address and forwards them to
IPMC over the sideband interface.
3. 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
