System Event Log Troubleshooting Guide for Intel ® S5500/S3420 series Server Boards
Basic decoding of a SEL Record
Revision 1.0 Intel order number G74211-001 5
Byte Field Description
8
9
Generator ID
(GID) RqSA and LUN if event was generated from IPMB.
Software ID if event was generated from system software.
Byte 1
[7:1] - 7-bit I2C. Slave Address, or 7-bit system software ID
[0] 0b = ID is IPMB Slave Address
1b = system software ID
Software ID values:
 0001h – BIOS POST for POST errors, RAS Configuration/State,
Timestamp Synch, OS Boot events
 0033h – BIOS SMI Handler
 0020h – BMC Firmware
 002Ch – ME Firmware
 0041h – Server Management Software
 00C0h – HSC Firmware – HSBP A
 00C2h = HSC Firmware – HSBP B
Byte 2
[7:4] - Channel number. Channel that event message was received over. 0h if the event
message was received from the system interface, primary IPMB, or internally generated
by the BMC.
[3:2] - reserved. Write as 00b.
[1:0] - IPMB device LUN if byte 1 holds Slave Address. 00b otherwise.
10 EvM Rev
(ER) Event Message format version. 04h = IPMI v2.0; 03h = IPMI v1.0
11 Sensor Type
(ST) Sensor Type Code for sensor that generated the event
12 Sensor #
(SN) Number of sensor that generated the event (From SDR)
13 Event Dir |
Event Type
(EDIR) Event Dir
[7] - 0b = Assertion event.
1b = Deassertion event.
Event Type
Type of trigger for the event, for example, critical threshold going high, state asserted,
and so on. Also indicates class of the event. For example, discrete, threshold, or OEM.
The Event Type field is encoded using the Event/Reading Type Code.
[6:0] - Event Type Codes
01h = Threshold (States = 0x00 – 0x0b)
02h – 0ch = Discrete
6Fh = Sensor-Specific
70-7Fh = OEM
