Baseboard Management Controller
The baseboard management controller supports the industry-standard Intelligent
Platform Management Interface (IPMI) specification. This specification describes the
management features that have been built into the system board. These features
include: diagnostics (both local and remote) console support, configuration management,
hardware management and troubleshooting.
The baseboard management controller provides the following:
• Compliance with Intelligent Platform Management Interface 1.0
• Tachometer inputs for fan speed monitoring
• Pulse width modulator outputs for fan speed control
• Push-button inputs for front panel buttons and switches
• One serial port, multiplexed with the system console port
• Remote access and intelligent chassis management bus (ICMB) support
• Three I2C master/slave ports (one the ports is used for IPMB)
• Low pin count (LPC) bus provides access to three keyboard controller style (KCS)
and one-block transfer (BT) interface
• 32-bit ARM7 RISC processor
• 160-pin low profile flat pack (LQFP) package
• Firmware is provided for the following interfaces:
— Intelligent platform management interface (IPMI)
— Intelligent platform management bus (IPMB)
SCSI Controller
The SCSI controller is an LSI Logic 53C1030 chip. This chip is fully compliant with the
SCSI Peripheral Interface-4 Specification (SPI-4). The 53C1030 adheres to the PCI-X
addendum to the PCI Local Specification and is hard-wired to PCI ID 1 which
corresponds to bit 17 of the PCI AD bus.
