The BMC provides a system status on the front panel LEDs. For more information, refer to
Section 5.7.2.

BMC Self Test
The BMC performs tests during initialization. If a failure is determined, such as a corrupt BMC
SDR, then the BMC stores the error internally. BMC or BMC subsystem failures detected during
regular BMC operation can also be stored internally. The
IPMI 2.0
Get Self Test Results
command can be used to return the first error detected.
Table 36 shows self-test errors that may be posted. Not all tests are performed as part of the
BMC initialization.

Messaging Interfaces
This section describes the supported BMC communication interfaces:
Host SMS Interface via low pin count (LPC)/keyboard controller style (KCS) interface
Host SMM interface via low pin count (LPC)/keyboard controller style (KCS) interface
Intelligent Platform Management Bus (IPMB) I
2
C interface
Emergency management port (EMP) using the IPMI-over-serial protocols for serial
remote access
LAN interface using the IPMI-over-LAN protocols
These specifications are defined in the following sub-sections.

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. The following table
shows the standard channel assignments:
