Although this bus supports IPMB and IPMI protocols, it is a private bus.Figure 7. BMC IPMB Message Reception4.8 IPMI Serial FeatureThe IPMI 2.0 Intel implementation of IPMI-over-serial was known as the emergencymanagement port (EMP) interface before IPMI 1.0. The EMP nomenclature is no longer used.The BMC only supports terminal mode – direct connect on the serial interface.The primary goal of providing an out-of-band RS-232 connection is to give systemadministrators the ability to access low-level server management firmware functions by usingcommonly available tools. To make it easy to use and to provide high-compatibility with LANand IPMB protocols, this protocol design adopts some features of both the LAN and IPMBprotocols.Revision 1.1Intel ® Confidential 63
