Figure 29. SOL Block Diagram

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 I2C/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
