Intel NetStructure
®
MPCBL0010 Single Board Computer
Technical Product Specification October 2006
146 Order Number: 304120
Figure 27 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 the base interface
Ethernet controller. This connectivity is not shared with IPMB-0 or any other I
2
C/
SMBus/IPMB connections that the IPMC may provide on the blade for hardware
management.
2. The base interface Ethernet controller, which provides a sideband interface port to
the IPMC over which SOL traffic is redirected
The Ethernet controller also filters packets based on MAC address, RMCP port
number, or IP address and forwards the packets to the 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 transformation
