2. Basic Decoding of a SEL Record
The System Event Log (SEL) record format is defined in the IPMI Specification. The following section provides a basic definition for
each of the fields in a SEL. For more details see the IPMI Specification.
The definitions for the standard SEL can be found in Table 1.
The definitions for the OEM defined event logs can be found in Table 3 and Table 4.
2.1 Default Values in the SEL Records
Unless otherwise noted in the event record descriptions the following are the default values in all SEL entries.
Byte [3] = Record Type (RT) = 02h = System event record
Byte [9:8] = Generator ID = 0020h = BMC Firmware
Byte [10] = Event Message Revision (ER) = 04h = IPMI 2.0
Table 1. SEL Record Format
ID used for SEL Record access.
[7:0] – Record Type
02h = System event record
C0h-DFh = OEM timestamped, bytes 8-16 OEM defined (See Table 3)
E0h-FFh = OEM non-timestamped, bytes 4-16 OEM defined (See Table 4)
Time when event was logged. LS byte first.
Example: TS:[29][76][68][4C] = 4C687629h = 1281914409 = Sun, 15 Aug 2010
23:20:09 UTC
Note: There are various websites that will convert the raw number to a date/time.
