1-12 System Overview

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 six Ultra-160/M SCA drives. Controller B, the Wide Ultra 2 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 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 addresses and can be enabled separately. 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 for devices other than keyboard or mouse.

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 or direct connection to a manager system. Events monitored by the manager system include over-temperature and over-voltage 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.

1-14 System Overview

ACPI

The Advanced Configuration and Power Interface (ACPI) aware operating system can place the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. However, in this state the power supply is still on and the processors are still dissipating some power such that the power supply fan and processor fans are still running.

Note:

ACPI requires an operating system that supports its

feature.

This server system BIOS supports sleep states s0, s1, s4, and s5. However, with future versions of Microsoft Windows 9X that support ACPI, the system BIOS only supports sleep states s0, s1, and s5. With future versions of Microsoft Windows NT that support ACPI, the system BIOS will only support sleep states s0, s1, s4, and s5.

CAUTION

Only when the AC power is disconnected is the system completely off.

The sleep states are defined as follows:

s0: Normal running state.

s1: Processor sleep state.

No context will be lost in this state and the processor caches will maintain coherency.

s4: Hibernate or Save to Disk.

The memory and machine state are saved to disk. Pressing the power button or other wakeup event restores the system state from the disk and resumes normal operation. This assumes that no hardware changes have been made to the system while it was off.

s5: Soft off.

Only the RTC section of the chipset and the BMC are running in this state.

AC Link Mode

The AC link mode allows the system to monitor its AC input power so that when the AC input power is lost and then restored the system will return itself to one of three preselected settings, listed as follows:

Power On

Last State (Factory Default Setting)

Stay Off.

The AC link mode settings can be changed by running the BIOS Setup Utility (F2). Refer to Chapter 3 "Configuring Your System."

System Overview 1-15

Remote Power-On (Wake ON LAN) Function

The remote power-on function turns on the system power by way of a network or modem. If the system power is set to OFF, it can be turned on remotely by sending a specific packet from the main computer to the remote system. This feature can be enabled or disabled using the BIOS Setup Utility. See Chapter 3.

System Security

To help prevent unauthorized entry or use of the system, the system includes a full lockable front panel and Server Management software that monitors the system intrusion switches.

Security with Mechanical Locks and Monitoring

The front panel of the tower-based system contains a mechanical lock and an intrusion switch to prevent access to the front of the computer chassis. The computer chassis includes an interlock switch on the side cover. When any these covers are opened, the switch transmits an alarm signal to the system board, where server management software processes the signal.

Software Locks via the System Setup Utility

The BIOS Setup Utility provides a number of security features to prevent unauthorized or accidental access to the system. Once the security measures are enabled, access to the system is allowed only after the user enters the correct password(s). For example:

Enable the keyboard lockout timer so that the server requires a password to

reactivate the keyboard and mouse after a specified time-out period1 to 120minutes.

Set and enable an administrative password.

Set and enable a user password

Set secure mode to prevent keyboard or mouse input and to prevent use of the

front panel reset and power switches.

Disable writing to the diskette drive when secure mode is set.
