5.2.20.1
The mBMC supports two channels:
5.2.20.2
The mBMC supports one anonymous user (null user name) with a settable password. The IPMI
Set User Password command is supported.
5.2.20.3
All of the protocols used in the above mentioned interfaces are Request/Response protocols. A
Request Message is issued to an intelligent device, to which the device responds with a
Response Message.
As an example, with respect to the IPMB interface, both Request Messages and Response
Messages are transmitted on the bus using SMBus Master Write transfers. In other words, a
Request Message is issued from an intelligent device acting as an SMBus master, and is
received by an intelligent device as an SMBus slave. The corresponding Response Message is
issued from the responding intelligent device as an SMBus master, and is received by the
request originator as an SMBus slave.
5.2.20.4
The host communicates with the mBMC via the System Management Bus (SMBus). The
interface consists of three signals:
When the system main power is off (PWRGD signal is low), the host interface signals are in
TRI-STATE to perform “passive” bus isolation between the mBMC SCLH, SDAH and SMBAH
signals and the SMBus controller signals. The passive bus isolation can be disabled by host
SMBus isolation control (offset 05h;) to support various system designs.
The mBMC is a slave device on the bus. The host interface is designed to support polled
operations. Host applications can optionally handle an SMBus alert interrupt, in case the mBMC
