System Overview 1-7

Power Supply

Your server may be configured with one power factor correction (PFC) 300-Watt power supply for non-redundant non-hot-swap systems or two 350-Watt thin power supply units for redundant hot-swap systems.

Each power supply unit has auto-ranging inputs that select 100 – 120 Vac or 200 – 240 Vac at an operating frequency of 50/60 Hz. It is designed to comply with existing emission standards and provides sufficient power for a fully loaded system configuration.

Peripheral Bays

The system supports a variety of standard PC AT-compatible peripheral devices. The chassis includes these peripheral bays:

A 3.5-inch front panel bay for mounting the standard 3.5" diskette drive

(supports 720 KB and 1.44 MB diskette media).

A front panel bay for mounting the standard 24X (slim) CD-ROM drive.

Two 5.25-inch removable media front panel bays for mounting half-height 5.25"

peripheral devices: optional tape drives, etc.

Your system may include hot-swap SCSI hard disk drive bays for mounting up to

five hot-swap disk drives in easily removable drive carriers. Each drive has a set of two lights to indicate the fault or other status: power-on (green LED), activity (flashing green LED), fault (yellow LED). For mounting additional SCSI hard disk drives an optional five SCSI hard disk drive cage is available

Note:

swap back plane that require an 80-pin single connector attachment (SCA) connector on the drives that you install.

SAF-TE Logic

Note:

SCSI disk drive cage. SAF-TE Logic is not available in systems that include the non-hot-swap hard SCSI disk drive cage.

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.

The hot-swap SCSI hard disk drive bays contain a hot-

System Overview 1-9

Pentium III Processor

Depending on system configuration, each system includes one or two Pentium III processors. Each Pentium III processor plugs into a standard PGA370 connector. The processor comes with either 256K or 512K cache.

When two processors are installed, both processors must be of identical bus and core speed. When only one processor is installed, the other processor socket must have a terminator card installed.

The processor external interface operates at a maximum of 133 MHz. The second-level cache is located on the substrate of the processor cartridge. The cache includes burst pipelined synchronous static RAM (BSRAM).

System Memory

The system board contains six 168-pin DIMM sockets. Memory is partitioned as three banks of registered SDRAM DIMMs (PC133 compatible) that must be populated in pairs, each providing 72 bits of buffered two-way interleaved memory (64-bit main memory plus ECC). Your system may include from 256 MB to 6 GB of memory, using up to six DIMMs.

System memory begins at address 0 and is continuous (flat addressing) up to the maximum amount of DRAM installed (exception: system memory is noncontiguous in the ranges defined as memory holes using configuration registers). The system supports both base (conventional) and extended memory.

I/O Expansion Slots

The server's expansion capabilities meet the needs of file and application servers for high performance I/O by providing PCI expansion slots.

Real-Time Clock/Calendar

The real-time clock provides system clock/calendar information stored in a non-volatile memory (NVRAM). The real-time clock lithium battery provides power backup for the real-time clock.

BIOS

A BIOS and Setup Utility are located in the Flash EPROM on the system board and include support for system setup and legacy device configuration. A number of security, reliability, and management features also have been incorporated to meet vital server needs.

IDE Controller

The system includes a dual channel enhanced IDE 32 bit interface controller for compatible IDE devices. The controller has a connector located on the system board that supports a master and a slave device. The IDE controller provides support for the internally mounted CD-ROM and supports ATA-66 synchronous DMA mode transfers.

The device controls:

PIO and DMA transfer modes

Mode 4 timings

Transfer rates up to 66 MB/s

Buffering for PCI/IDE burst transfers

Master/slave IDE mode

Up to two devices.

Keyboard and Mouse Controller

The keyboard and mouse controller is PS/2 compatible.

Network Controller

The system board includes two 10BASE-T/100BASE-TX network controllers based on the Intel 82550 Fast Ethernet PCI Bus Controller. As a PCI bus master, the controller can burst data at up to 132 MB/sec. The controller contains two receive and transmit FIFO buffers that prevent data overruns or underruns while waiting for access to the PCI bus. The controller has the following:

32-bit PCI bus master interface (direct drive of bus), compatible with PCI Bus

Specification, Revision 2.1

Chained memory structure with improved dynamic transmit chaining for

enhanced performance

Programmable transmit threshold for improved bus utilization

Early receive interrupt for concurrent processing of receive data

On-chip counters for network management

Autodetect and autoswitching for 10 or 100 Mbps network speeds

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 AIC7899W dual function SCSI controller. The AIC7899W provides Ultra-160 SCSI interfaces as two independent PCI functions. As implemented on the system board, interface A attaches to an Ultra-160 SCSI backplane that supports up to ten Ultra-160 SCA drives in redundant configuration. Controller B may be used to support SCSI devices in the removable media bays or external to the cabinet.

Video Controller

The system has an integrated ATI Rage XL 64 bit high-performance VGA 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 super I/O (PC87417) advanced integrated peripheral controller supports two serial ports (one on rear I/O panel and one 10 pin header connector on the system board), four 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, VGA monitor, two serial port connectors, a parallel port connector, two LAN ports, and four USB connections (three on rear I/O panel and one on front panel) 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 Records (SDRs), 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.
