4.2.1.2 IPMC - System Manager Interface
The Section 24 of [IPMI 2.0] describes how IPMI messages can be sent to and from the IPMC encapsulated in
RMCP (Remote Management Control Protocol) packets datagrams. This capability is also referred to as “IPMI
over LAN” (IOL). IPMI also defines the associated LAN-specific configuration interfaces for setting things
such as IP addresses other options, as well as commands for discovering IPMI-based systems. The Distributed
Management Task Force (DMTF) specifies the RMCP format. This LAN communication path make the Front
Blade Unit reachable to the System Manager for any management action (IPMC firmware upgrade, query of all
FRU Data, CPU reset etc.) without the need to go through the ShMC.
4.2.1.3 IPMC - System Event Log
The Kontron IPMC implementation includes a Local System Event Log device as specified in the Section 31 of
[IPMI 2.0]. The local System Event Log is a nonvolatile repository for the front board and all managed FRU
events (RTM). The local SEL provides space for more than 5000 entries. However, even if blade events are
logged into the local SEL, the IPMI platform event messages are still generated by the IPMC's Event
Generator and sent to the centralized SEL hosted by the Shelf Manager through the IPMB-0 communication
path - [PICMG 3.0] chapter 3.5; [IPMI 2.0] Section 29. Local SEL is useful for maintenance purposes and
provides access to the events when the FRU is extracted from the Shelf.

4.3.1 Supported commands
The table below lists the IPMI commands supported by the IPMC. This table is identical as the one provided by
AMC.0 and PICMG 3.0. The last column states the Kontron support for the specific command.
