Baseboard Management Controller

The baseboard management controller (BMC) 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: local and remote diagnostics, 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 server console port
• Remote access and intelligent chassis management bus (ICMB) support
2
• Three I C primary/secondary 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 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-3 Specification (SPI-3). It has two independent SCSI channels supporting devices at speeds up to
320 Mb/second 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 controller (PCI649) supports the ATAPI zero to five modes (from 16 to 100 Mb/s). The usable speed
on this server is limited to 16 MHz (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 primary type, for the DVD peripheral.
