Overview

Your server is a modular, multiprocessing server based on the Intel Xeon microprocessor. It is a solid performer and offers the latest technology. The

combination of compute performance, memory capacity, and integrated I/O provides a high performance environment for many server market applications. These range from large corporations supporting remote offices to small companies looking to obtain basic connectivity capability such as file and print services, e-mail, web access, web site server, etc.

Your server is a rack-mount system. See Figure 1-1.Your server conveniently installs into a standard EIA 19-inch rack assembly.



Figure 1-1. System Front View

Your server includes a 3.5-inch diskette drive, a CD-ROM drive, six hot-swap SCSI hard disk drive bays, and a removable media device bay. The hot-swap SCSI hard disk drive bays support up to six 1.0-inch SCSI hard disk drives that can be swapped in or out of the system without powering it down, if RAID functionality is configured in the system.

Alternately, your server can be configured to include a 7th SCSI hard disk drive. This configuration includes a removable media drive bay and seven hot-swap SCSI hard disk drive bays. The removable media drive bay may be used for installation of a high-speed tape drive.

As application requirements increase, you can expand your server with an additional processor, additional memory, add-in boards and peripheral devices: tape devices, and hard disk drives.

1-2 System Overview

System Features

Your system features the following major components:

! Single or dual high-performance Intel™ Xeon™ 2.00GHz or 2.80GHz

processors.

! 256 MB to 6 GB of ECC SDRAM two way interleaved memory, using up to six

DIMMs.

! Six PCI expansion slots for add-in boards (three full-length, full height 64-

bit/100MHz PCI-X riser slots and three low profile 64-bit/100MHz riser slots).

! A maximum of seven hot-swap SCSI hard disk drive bays accessible from the

front of the chassis.

! Hot-swap SCSI disk drive backplane; a failed drive can be removed and replaced

with a new drive without system power being turned off (if an optional Redundant Array of Independent Disks (RAID) controller is installed.)

! High degree of SCSI disk fault tolerance and advanced disk array management

features through the use of RAID technology, if an optional RAID controller is installed.

! Embedded PC-compatible support (serial, parallel, mouse, keyboard, diskette,

USB, LAN, and video).

! Integrated onboard ATI RAGE XL Video Graphics Array (VGA) controller with

8MB of video memory (VRAM).

! Adaptec AIC-7902W SCSI controller providing dual channel Ultra-320 SCSI

interfaces.

! Integrated Network Interface Controller (NIC), a dual channel Intel 82546EB

Gigabit Ethernet LAN controller supporting 10Base-T/100Base-TX/1000Base-T network systems.

! Dual channel enhanced IDE controller (secondary channel supported only). ! One 3.5-inch removable media expansion bays. ! IDE 24X CD-ROM drive and 3 ½-inch diskette drive. ! Three integrated Universal Serial Bus (USB) ports, one located at the front panel

and two located at the rear panel.

! Hardware monitors (temperature, fans, and voltage) and software monitors to

indicate failures.

System Overview 1-3

! Chassis that supports up to two power supply modules. The additional power

supply is needed to provide hot-swappable redundant power (i.e., the system will continue to operate with a single power supply failure). With two power modules installed, one power module can be easily removed or installed from the back of the chassis without turning the system power off.

! Fully lockable front bezel including Server Management software that monitors

the front bezel intrusion switch.

1-4 System Overview

System Chassis

The system chassis (Figure 1-2) is an easy-to-expand, fabricated metal structure. The major system components are shown in the following illustrations.

A SCSI backplane B Power supply unit C Cooling fans D Processor duct (dashed-line) E Riser card (for full-height boards) F Processor (mounted under the CPU and heat sink) G DIMM (Two DIMMs are mounted as standard in slots #1A and #1B.) H Mother board I Riser card (for only low-profile boards) J Front panel board K Cover open sensor L CD-ROM drive M Backup device bay N Floppy disk drive O Flex bays P Disk bays

Figure 1-2. System Chassis

System Overview 1-5

Power Supply

The power supply consists of the power supply bay and one power supply module. A second power supply module can be purchased to provide a redundant, 1+1 system. With either configuration, the power supply provides 500 watts of power and is designed to minimize EMI.

The power subsystem supports implementation of remote management features including remote enable that permits power to be activated from a variety of sources.

Peripheral Bays

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

! A removable media front panel bay for mounting a half-height 3.5-inch

peripheral device such as an optional tape drive.

! Depending on your configuration, your server includes either six or seven hot-

swap SCSI hard disk drive bays for mounting hard disk drives installed in easily removable drive carriers.

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

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

The flex bay can be used with either the standard CD-ROM/FDD module or a seventh hot swappable SCSI HDD. The CD-ROM/FDD module may only be inserted or removed from the flex bay when system power is turned off. The CD-ROM/FDD module is NOT hot swappable. The standard 3.5-inch diskette drive supports 720 KB and 1.44 MB diskette media.

The chassis includes four 60-mm non-hot-swappable system fans for cooling the processor(s), hard drives, and add-in cards. The system fans are mounted in a fan assembly located in the middle of the chassis to pull cooling air through the chassis. The power supply contains a single fan for cooling.

SAF-TE Logic

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.

Depending on system configuration, each system includes one or two Intel Xeon

2.00GHz or 2.80GHz processors. Each processor plugs into a INT3/FCPGA socket package. The processor includes a 512K cache. When two processors are installed, both processors must be of identical bus and core speed.

The processor external interface operates at a maximum of 400MHz. 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 (DDR200 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.

PCI Riser Slots

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

The system board has three full-length, full height 64-bit/100MHz PCI-X slots (riser slot B) and three low profile 64-bit/100MHz PCI slots (riser slot A).

Riser slot A provides the following features:

! Bus speed up to 100MHz ! 184 pin, 5 volt keyed, 64-bit expansion slot connector ! Support for a 3-slot PCI riser card ! Support for only low profile PCI cards

Riser slot B provides the following features:

! Bus speed up to 100 MHz ! 184 pin, 5 volt keyed, 64-bit expansion slot connector ! Support for a 3-slot PCI riser card ! Support for only full length, full height PCI cards.

1-8 System Overview

Video Controller

The system board uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM. The embedded SVGA video subsystem supports:

! Resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D ! CRT and LCD monitors up to 100 Hz vertical refresh rate.

The system board supports disabling of the onboard video through the BIOS setup menu or when a plug in video card is installed in any of the PCI slots.

SCSI Controller

The system board includes an embedded Adaptec AIC7902W dual function SCSI controller. The AIC7902W provides Ultra-320 SCSI interfaces as two independent PCI functions. As implemented on the system board, the interface attaches to an Ultra-320 SCSI backplane that supports up to seven Ultra-320 SCA drives.

Network Controller

The system board uses a dual-channel Intel® 82546EB Gigabit Ethernet Controller and supports 10Base-T/100Base-TX/1000Base-T network subsystems.

The 82546EB controller supports the following features:

! 64-bit, 100 MHz PCI-X interface ! Integrated IEEE 802.3 10Base-T, 100Base-TX, and 1000Base-T compatible

Keyboard and Mouse

The keyboard/mouse controller is PS/2-compatible. The server may be locked automatically if there is no keyboard or mouse activity for a predefined length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse do not respond until the previously stored password is entered. A Y-cable can be used if both a PS/2 mouse and keyboard are required at the same time.

RJ-45 Serial Port

The rear RJ-45 serial port is a fully functional serial port that supports any standard serial device and provides support for serial concentrators. For server applications that use a serial concentrator to access the server management features of the mother board, a standard 8-pin CAT-5 cable from the serial concentrator is plugged directly into the rear RJ-45 serial port. The 8 pins of the RJ-45 connector can be configured to match either of two pin-out standards used by serial port devices.

To accommodate either standard, the J5A2 jumper block located directly behind the rear RJ-45 serial port must be jumpered appropriately according to the desired standard.

ACPI

An 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.

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.

1-10 System Overview

Note: The system is Off only when the AC power cord is disconnected.

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.

System Functions

The following subsections describe select system functions.

Degradation Feature

The degradation feature automatically isolates a failed DIMM or processor to assure continuous operation of the server when the POST (Power On Self-Test, self-diagnosis program after power on) detects such a DIMM or processor.

Note: The degradation feature is only available when at least four

DIMMs or two processors are installed.

Failed DIMMs and processors may be identified by POST displays, or by using the BIOS setup utility (see Chapter 3). They may also be identified on a system that has ESMPRO installed.

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."

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.

1-12 System Overview

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 front bezel intrusion switch.

Security with Mechanical Locks and Monitoring

The front bezel contains a mechanical lock and an intrusion switch to prevent access to the front of the computer chassis. The computer chassis includes an intrusion switch on the top cover. When any of 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 120minutes.

! Set and enable an administrative password.

 1 to

! 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.

! Activate a hot key combination to enter secure mode quickly. ! Disables access to the boot sector of the operating system hard disk drive. ! Disable writing to the diskette drive when secure mode is set.

Using Passwords

You can set either the user password, the supervisor password, or both passwords. If only the user password is set, you:

! Must enter the user password to enter BIOS Setup. ! Must enter the user password to boot the server if Password on Boot is enabled in

the BIOS Setup.

! Must enter the user password to exit secure mode.

If only the supervisor password is set, you:

! Must enter the supervisor password to enter BIOS Setup. ! Must enter the supervisor password to boot the server if Password on Boot is

enabled in the BIOS Setup.

! Must enter the supervisor password to exit secure mode.

Secure Mode

Configure and enable the secure boot mode by using the BIOS Setup. When secure mode is in effect:

! You can boot the server and the operating system will run, but you must enter the

switches.

Taking the server out of secure mode does not change the state of system power. That is, if you press and release the power switch while secure mode is in effect, the system will not be powered off when secure mode is later removed. However, if the front panel power switch remains depressed when secure mode is removed, the server will be powered off.
