The SCSI backplane includes SAF-TE (SCSI Accessed Fault Tolerant Enclosure) logic that provides an interface to the disk subsystem that supports status signals, hot swapping drives, and enclosure monitoring.

The transport mechanism for the standardized alert detection and status reporting is the SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually monitored and the conditions then reported over the SCSI bus to the system. When used with RAID management software the user can be alerted of impending or imminent disk conditions requiring attention. This allows the user to react to conditions that could normally go unnoticed until data loss.

SCSI Controller

The system board includes an embedded Adaptec AIC7899 dual function SCSI controller. The AIC7899 provides Ultra-160/M and Wide Ultra 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 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.

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.
