Support for both 10 Mbps and 100 Mbps networks, capable of full or half

duplex, with back-to-back transmit at 100 Mbps

Support for Wake On LAN.

SCSI Controller

The system board includes an embedded Adaptec AIC7899 dual function SCSI controller. The AIC7899 provides Ultra-160/M and Wide Ultra2 SCSI interfaces as two independent PCI functions. As implemented on the system board, interface A attaches to an Ultra-160/M SCSI backplane that supports up to seven Ultra-160/M SCA drives. Controller B the Wide Ultra2 SCSI interface may be used to support SCSI devices in the removable media bays.

Video Controller

The system has an integrated ATI Rage IIC 64 bit high-performance SVGA subsystem that supports the following:

BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA

4 MB of 10 ns onboard Synchronous Graphics Memory (SGRAM)

Pixel resolutions up to 1280 X 1024

Analog VGA monitors (single and multiple frequency, interlaced and

noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.

Peripheral Controller

The advanced integrated peripheral controller supports two serial ports, two universal serial bus ports, one parallel port, diskette drive, PS/2-compatible keyboard and mouse, and integrated Real Time Clock (RTC). The system provides the connector interface for each port.

Serial Ports

Both serial ports are relocatable. Each serial port can be set to one of four different COM ports and can be enabled separately. When enabled, each port can be programmed to generate edge or level sensitive interrupts. When disabled, serial port interrupts are available to add-in boards.

Parallel Port

One IEEE 1284-compatible 25-pin bidirectional EPP (supporting levels 1.7 and 1.9) parallel port is provided. BIOS programming enables the parallel port and determines the port address and interrupt. ECP mode is supported with 2 possible DMA channels. When disabled, the interrupt is available to add-in boards.

External Device Connectors

The external I/O connectors provide support for a PS/2 compatible mouse and a keyboard, for a SVGA monitor, 2 serial port connectors, a parallel port connector, LAN port, and two USB connections.

System Board Management Controller (BMC)

Server management is concentrated in the System Board Management Controller (BMC). The BMC and associated circuitry are powered from a 5Vdc standby voltage, which remains active when system power is switched off, but the ac power source is still on and connected.

The BMC supports the Management Workstation Application (MWA), which allows remote server management via a modem, LAN, or direct connection to a manager system. Events monitored by the manager system include over-temperature and overvoltage conditions, fan failure, or chassis intrusion.

Information on the Management Workstation Application (MWA) may be found in Appendix B of this User’s Guide.

One major function of the BMC is to autonomously monitor system management events, and log their occurrence in the nonvolatile System Event Log (SEL). The events being monitored include overtemperature and overvoltage conditions, fan failure, or chassis intrusion. To enable accurate monitoring, the BMC maintains the nonvolatile Sensor Data Record (SDR), from which sensor information can be retrieved. The BMC provides an ISA host interface to SDR sensor information, so that software running on the server can poll and retrieve the server's current status.

The BMC performs the following:

Monitors server board temperature and voltage

Monitors processor presence and controls Fault Resilient Boot (FRB)

Detects and indicates baseboard fan failure

Manages the SEL interface

Manages the SDR Repository interface

Monitors the SDR/SEL timestamp clock

Monitors the system management watchdog timer

Monitors the periodic SMI timer

Monitors the event receiver

Controls secure mode, including video blanking, diskette write-protect monitoring,

and front panel lock/unlock initiation

Controls Wake On LAN via Magic Packet support.
