6.3.8 System Event Sensor
The BMC supports a System Event sensor and logs SEL event for following events.
Table 20. Support System Event Sensor Offsets
Offset
Description
Event Logging
02h
OEM code (Undetermined system HW failure)
Assertion and
Deassertion
04h
PEF action
Assertion only
For offset 2, OEM code will be logged in event data byte 2 to indicate the type of failure. Only
one value will be supported at this time, but others may be added in the future. The code for this
particular fault will be 0x00 (PECI access failure) and all other values reserved. Upon detection
of the CPU PECI fault condition, the offset shall assert. It shall deassert upon system power
cycle or system reset. Assertion of offset 02h shall contribute a “fatal” condition to the system
status as reflected in the Front Panel system status LED.
6.4 Channel Management
This section describes the supported BMC communication interfaces:
 Host SMS interface by means of low pin count (LPC)/keyboard controller style (KCS)
interface
 Host SMM interface by means of low pin count (LPC)/keyboard controller style (KCS)
interface
 Intelligent Platform Management Bus (IPMB) I

C interface
 LAN interface using the IPMI-over-LAN protocols
6.4.1 Channel Management
Every messaging interface is assigned an IPMI channel ID by IPMI 2.0. Commands are
provided to configure each channel for privilege levels and access modes. Table 21 shows the
standard channel assignments:
