Platform Management Architecture
5.1.5.1
Channel Management
The National Semiconductor PC87431 integrated management controller supports two
channels:
• System interface
• 802.3 LAN

5.1.5.2
User Model
The National Semiconductor PC87431 integrated management controller supports one
anonymous user (null user name) with a settable password. The IPMI command to set the
password is not supported.
5.1.5.3
Request/Response Protocol
All of the protocols used in the host interface and the LOM interface are Request/Response
protocols. A Request Message is issued to an intelligent device, to which the device responds
with a separate Response Message.
5.1.5.4
Host to National Semiconductor PC87431 integrated management
controller Communication Interface
The host communicates with the National Semiconductor PC87431 integrated management
controller via the System Management Bus (SMBus). The interface consists of three signals:
• SMBus clock signal (SCLH)
• SMBus data signal (SDAH)
• Optional SMBus alert signal (SMBAH). The signal notifies the host that the PC87431x
has data to provide.
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 National Semiconductor PC87431
integrated management controller SCLH, SDAH and SMBAH signals and the SMBus controller
signals. The passive bus isolation can be disabled by host SMBus isolation control to support
various system designs.
