PC87431M/S/C mini-Baseboard Management Controller (m BMC) November 2002 Revision 1.4 PC87431M/S/C mini-Baseboard Management Controller (m BMC) General Description The National Semiconductor PC87431x family of mini Baseboard Management Controllers (m BMC) is a light version of the IPMI v1.5 BMC. It is targeted for a wide range of remote-controlled platforms such as servers, workstations, hubs and printers. The PC87431x incorporates an embedded microcontroller, three System Management Bus (SMBus®) interfaces, a Chassis Management interface, Bi-color LED control, an integrated flash, Fan control, 12 ADC channels, and Digital Input Event and General-Purpose Output pins. The PC87431x interfaces with the host via a slave SMBus interface; it interfaces with the LAN On Motherboard (LOM) and with peripherals via two independent master SMBus interfaces. The PC87431x also supports distributed management architecture via the Intelligent Platform Management Bus (IPMB). In addition, the PC87431x includes an inhibit strap to enable the system to work with the daughter board of an advanced BMC. The PC87431x, like other members of National’s Advanced I/O family, is PC01 and ACPI pliant ® Outstanding Features s s s s s s s s s s s s s s s s s s s s s Canned solution LAN mands follow IPMI v1.5 MD5 secure authentication Support for a variety of popular LOMs Field Replaceable Unit (FRU) Inventory System Event Log (SEL) Sensor Data Record (SDR) Repository Platform Event Filtering (PEF) Remote secure reset, Power On/Off Remote settable BIOS boot options BIOS Alerting interface System health monitoring using SMBus-based sensors LAN Alerting in PET format Watchdog Timer Host, LOM and Peripheral interfaces, via SMBus Intelligent Platform Management Bus (PC87431C) Digital Input Event pins and General-Purpose Output pins Integrated Fan control and ADC (PC87431S/C) Integrated flash, to reduce system cost Two LEDs, with Bi-color LED control Inhibit strap, to enable the system to work with...
