The BMC messaging interfaces comply with the Intelligent Platform Management
Interface Specification, Version 2.0. The MIC-3392 provides 4 messaging interface
channels.
! LPC/KCS channel: Connects the H8S/2167 to the system LPC bus. Firmware
sets 1 host interface over LPC:KCS for SMS.
! IPMB channel: Connects IPMB devices or connects to the H8S/2167's I2C_0
interface.
! Serial port: The H8S/2167 supports one serial port for out-of-band manage-
ment (OOB) as well as one serial port for firmware flash update. Serial Port 0 is
selected for OOB serial port
! LAN channel: OOB management over LAN is accomplished by a sharing a NIC
(LAN2 or LAN3). This messaging interface channel connects the H8S/2167's
I2C interface to the NIC's SMBus interface.
