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). It has two independent SCSI channels supporting devices at speeds up to
320 MB/sec. each. 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.

IDE Interface

The IDE interface provides support for an internal CD-RW or a DVD reader through an internal IDE
connector and cable. This interface supports the master capability.
The IDE controller (PCI649) supports the ATAPI zero (0) to five (5) modes (from 16 to 100 MB/s). The usable
speed on this system is limited to 16MHz (ATA-33 mode, 33 MB/s) because the slimline CD/DVD devices do
not support the ATA-66 and 100 modes.
The primary IDE channel is the only channel that is implemented. The IDE cable provides only one drive
connector, of the Master type, for the optical storage peripheral.

10/100 BT Management LAN C

The 10/100 LAN port provides:
• A management LAN interface for operating system level manageability applications.
