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 IPMI 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
Three I2C primary/secondary ports (one port 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/s 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.
