Peripherals

3.5-inch Diskette Drive

The 3.5-inch diskette drive in the 3.5-inch peripheral bay supports 720 KB, and 1.44 MB media.
The drive is externally accessible from the front of the system.

3.5-inch Hard Drive Bays

The chassis contains one bay for two 3.5-inch-wide (1" high or 1-5/8" high) LVDS SCSI hard
drives with internal cabling. An optional hot-swap-capable backplane can accommodate six

3.5-inch-wide (1" high) or three 3.5-inch (1-7/8" high) hard drives, which are accessed externally
from the front of the system. To upgrade to a backplane, or to upgrade your existing backplane,
you must buy a kit.

As part of the hot-swap implementation, a drive carrier is required. The drives are mounted in the
carrier with four fasteners and the carrier snaps into the chassis. Drives whose power exceeds 15
watts require heatsinks and system fans for extra cooling. These parts are available in an optional
kit.

• For information on how and when to install heatsinks, see “Installing Heatsinks on High-

Power Drives” on page 82.

• For information on how and when to install extra fans, see “Installing Fans for High-Power

Drives” on page 106.

A single metal EMI shield and plastic door cover the drive bays. A hot-docking bay is provided
for drives that are 3.5 inches wide and 1 inch high. Drives can consume up to 22 watts of power
and must be specified to run at a maximum ambient temperature of 55 °C.

The system was designed to allow the user to install a Redundant Array of Independent Disks
(RAID). A software implementation with onboard SCSI or an add-in board can be used to set up
RAID applications.

5.25-inch Removable Media Device Bays

The chassis has three 5.25-inch half-height bays that are accessible from the front of the system.
These bays are intended to provide space for tape backup or other removable devices.

You can convert the 5.25-inch bays to a single full-height bay. We recommend that you do not use
these bays for hard disk drives, because they generate EMI (increasing ESD susceptibility), and
because of inadequate cooling.

16

Power Supplies

The chassis can be configured with one, two, or three 400-watt power supplies, each designed to
minimize EMI and RFI. Each supply operates within the following voltage ranges and is rated as
follows:

• 100-120 V∼ at 50/60 Hertz (Hz); 7.6 A maximum

• 200-240 V∼ at 50/60 Hz; 3.8 A maximum

The DC output voltages of each power supply are:

• +3.3 V at 36 A max

• +5 V at 24 A max (total combined output of +3.3 V and +5.5 V not to exceed 195 W)

• +12 V at 18.0 A with 19.0 A <10ms peak

• +24 V at 50mA

• -12 V at 0.5 A

• +5 V standby 1.5 A

Power is sourced through the power cable to the 20-pin main connectors on the baseboard.
Remote sensing signals are provided through the cable to the 14-pin auxiliary connector on the
baseboard.

System Cooling

The minimum chassis configuration includes three fans for cooling and airflow (and can accept up
to five more). The number of additional fans depends on your configuration: one fan for each
power supply (up to three) and two fans for cooling hard drives.

NOTE

✏

The access cover must be on the system for proper cooling.

Processor

Each Pentium II Xeon processor is packaged in a single edge contact (S.E.C.) cartridge. The
cartridge includes the processor core with an integrated 16 KB primary (L1) cache; the secondary
(L2) cache; a thermal plate; and a back cover.

™

The processor implements the MMX

™

the 8086, 80286, Intel386

, Intel486™, Pentium, and Pentium Pro processors. The processor's
numeric coprocessor significantly increases the speed of floating-point operations and complies
with ANSI/IEEE standard 754-1985.

Each S.E.C. cartridge connects to the baseboard through a 330-pin Slot 2 edge connector. The
cartridge is secured by a retention module attached to the baseboard. Depending on configuration,
your system has one to four processors.

The processor external interface is MP-ready and operates at 100 MHz. The processor contains a
local APIC unit for interrupt handling in multiprocessor (MP) and uniprocessor
(UP) environments.

The L2 cache is located on the substrate of the S.E.C. cartridge. The cache:

• Includes burst pipelined synchronous static RAM (BSRAM)

• Is offered in 512 KB, 1 MB, and 2 MB configurations

• Has ECC

• Operates at the full core clock rate

technology and maintains full backward compatibility with

21

Memory

Main memory resides on an add-in board, called a memory module, designed specifically for the
SC450NX MP server. The memory module contains slots for 16 DIMMs, each of which must be
at least 32 MB, and is attached to the baseboard through a 242-pin connector. Memory amounts
from 128 MB to 4 GB of DIMM are supported, with a 64/72-bit four-way-interleaved pathway to
main memory, which is also located on the module. The 16 slots are divided into four banks of
four slots each, labeled A through D. These banks support 4:1 interleaving. The memory
controller supports EDO DRAMs. The ECC used for the memory module is capable of correcting
single-bit errors (SBEs) and detecting 100 percent of double-bit errors over one code word. Nibble
error detection is also provided.

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.

• Base memory is located at addresses 00000h to 9FFFFh (the first 1 MB).

• Extended memory begins at address 0100000h (1 MB) and extends to FFFFFFFFh (4 GB),

which is the limit of supported addressable memory. The top of physical memory is a
maximum of 4 GB (to FFFFFFFFh).

NOTE

✏

Addressable memory can be extended to 64 GB under certain
configurations, but this server is configured to support 4 GB.

Some OSs and application programs use base memory while others use both conventional and
extended memory. Examples:

• Base memory: MS-DOS

†

, OS/2†, Windows NT†, and UNIX

†

• Conventional and extended memory: OS/2, Windows NT, and UNIX
MS-DOS does not use extended memory; however, some MS-DOS utility programs like RAM

disks, disk caches, print spoolers, and windowing environments use extended memory for better
performance.

BIOS automatically detects, sizes, and initializes the memory array, depending on the type, size,
and speed of the installed DIMMs, and reports memory size and allocation to the system via
configuration registers.

In a 4 GB configuration, a small part of memory (typically 32 MB) is not remapped above 4 GB.
If your OS does not support more than 4 GB of physical memory, this small part of the memory is
effectively lost.

NOTE

Peripherals

Super I/O Chip

The 87309 device supports two serial ports, one parallel port, diskette drive, and PS/2-compatible
keyboard and mouse. The system provides the connector interface for each port.

Serial Ports

Both serial ports are relocatable. By default, port A is physically the top connector, port B on the
bottom. Each serial port can be set to one of four different COMx ports, and each 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

The 25/15-pin connector stacks the parallel port over the VGA. The 87309 provides one
IEEE 1284-compatible 25-pin bidirectional EPP (supporting levels 1.7 and 1.9). BIOS
programming of the 87309 registers enables the parallel port and determines the port address and
interrupt. When disabled, the interrupt is available to add-in boards.

Add-in Board Slots

The baseboard has one ISA slot that is full-length if the wide SCSI-B slot is not used (and half­length if the wide SCSI-B slot is used); the ISA slot supports slave-only boards and is shared with
PCI-B slot 4. The ISA has three embedded devices: the Super I/O chip, Baseboard Management
Controller (BMC), and flash memory for system BIOS. ISA features:

• Bus speed up to 8.33 MHz

• 16-bit memory addressing

• Type A transfers at 5.33 MB/sec

• Type B transfers at 8 MB/sec

• 8- or 16-bit data transfers

• Plug and Play ready

The baseboard has two 32-bit PCI bus segments: PCI-A and PCI-B. These provide seven slots for
PCI add-in boards: three on PCI-A and four on PCI-B. PCI-B4 is shared with the ISA slot.
PCI-A1 supports half-length boards only. The other slots support full-length boards. PCI features:

• 33 MHz bus speed

• 32-bit memory addressing

• 5 V signaling environment

• Burst transfers of up to 133 MB/sec

• 8-, 16-, or 32-bit data transfers

• Plug and Play ready

• Parity enabled

24

Video

The onboard, integrated Cirrus Logic CL-GD5480 64-bit VGA chip contains an SVGA controller

†

that is fully compatible with these video standards: CGA
VGA. The standard system configuration comes with 2 MB of 10 ns onboard video memory. The
video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 M colors.

The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced
and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.

You can not add video memory to this system. Depending on the environment, the controller
displays up to 16.7 M colors in some video resolutions. It also provides hardware-accelerated bit
block transfers (BITBLT) of data.

SCSI Controller

The baseboard includes two SCSI controllers. A narrow SCSI controller (SYM53C810AE) is on
the PCI-A bus, and a dual-channel wide LVD/SE (Ultra2/Ultra) SCSI controller (SYM53C896) is
on the PCI-B bus. The narrow provides support for the legacy 8-bit SCSI devices in the 5.25-inch
drive bays. The wide drives one SCSI backplane and provides support for external expansion.

Internally, each wide channel is identical, capable of operations using either 8- or 16-bit SCSI
providing 10 MB/sec (Fast-10) or 20 MB/sec (Fast-20) throughput, or 20 MB/sec (Ultra),
40 MB/sec (Ultra-wide) or 80 MB/sec (40 Mhz) (Ultra-2).

The SYM53C810AE (narrow) contains a high-performance SCSI core capable of Fast 8-bit SCSI
transfers in single-ended mode. It provides programmable active negation, PCI zero wait-state
bursts of faster than 110 MB/sec at 33 MHz, and SCSI transfer rates from 5 to 10 MB/sec. The
narrow SCSI comes in a 100-pin rectangular plastic quad flat pack (PQFP) and provides an “AND
tree” structure for testing component connectivity.

The Sym53C896 (wide) contains a high-performance SCSI bus interface. It supports SE mode
with 8-bit (10 or 20 MB/sec) or 16-bit (20 or 40 MB/sec) transfers and LVD mode with
8-bit (40 MB/sec) or 16-bit (80 MB/sec) transfers in a 329-pin ball grid array (BGA) package.

Each controller has its own set of PCI configuration registers and SCSI I/O registers. As a
PCI 2.1 bus master, the SYM53C896 supports burst data transfers on PCI up to the maximum rate
of 132 MB/sec using on-chip buffers.

In the internal bay, the system supports up to six one-inch SCSI hard disk drives, plus, in the

5.25-inch removable media bays, three SCSI or IDE devices (the controller itself supports more
devices, but the 5.25-inch bay can contain a maximum of three devices). A wide SCSI cable
provides two connectors for Ultra SCSI devices (one of these connectors is for the optional SCSI
backplane, if your system has that). However, SCSI devices do not need to operate at the ultra
transfer rate. All drives on the bus must be Ultra-2 (LVD) to run at 80MB/sec (40Mhz). The 5,
10, and 20Mhz operations can coexist on the bus and each device will interact at its appropriate
speed.

No logic, termination, or resistor loads are required to connect devices to the SCSI controller other
than termination in the device at the end of the cable. The SCSI bus is terminated on the baseboard
with active terminators that can be disabled.

25

IDE Controller

IDE is a 16-bit interface for intelligent disk drives with AT† disk controller electronics onboard.
The PCI/ISA/IDE Accelerator, called PIIX4E, is a multifunction device on the baseboard that acts
as a PCI-based Fast IDE controller. The device controls:

• PIO and IDE DMA/bus master operations

• Mode 4 timings

• Transfer rates up to 22 MB/sec

• Buffering for PCI/IDE burst transfers

• Master/slave IDE mode

• Up to two drives for one IDE channel

NOTE

✏

18-inch maximum length of IDE cable on each channel: you can connect
an IDE signal cable, up to a maximum of 18 inches, to the IDE connector on
the baseboard. The cable can support two devices, one at the end of the
cable and one six inches from the end.

Keyboard and Mouse

The PS/2-compatible keyboard and mouse connectors are mounted in a single-stacked housing
with the mouse connector over the keyboard. External to the system, they appear as two
connectors.

The user can plug in the keyboard and mouse to either connector before powering up the system.
BIOS detects these and configures the keyboard controller accordingly.

The keyboard controller is functionally compatible with the 8042A microcontroller. The system
can be locked automatically if no keyboard or mouse activity occurs for a predefined length of
time, if specified through the SSU. Once the inactivity (lockout) timer has expired, the keyboard
and mouse do not respond until the previously stored password is entered.

26

Server Management

Server Management features are implemented using one microcontroller, the Baseboard
Management Controller (BMC).

Baseboard Management Controller (BMC)

The BMC and associated circuitry are powered from 5V_Standby, which remains active when
system power is switched off.

The primary function of the BMC is to autonomously monitor system platform management events
and log their occurrence in the nonvolatile System Event Log (SEL). These events include
overtemperature and overvoltage conditions, fan failure, or chassis intrusion. While monitoring,
the BMC maintains the nonvolatile sensor data record repository (SDRR), from which run-time
information can be retrieved. The BMC provides an ISA host interface to SDRR information, so
software running on the server can poll and retrieve the current status of the platform. A shared
register interface is defined for this purpose.

SEL contents can be retrieved after system failure for analysis by field service personnel using

®

system management tools like Intel
by 5V_Standby, SEL (and SDRR) information is also available via the interperipheral
management bus (IPMB). An emergency management board like the Intel LANDesk SMM board
can obtain the SEL and make it remotely accessible using a LAN or telephone line connection.
During monitoring, the BMC performs the following functions:

• Baseboard temperature and voltage monitoring

• Processor presence monitoring and FRB control

• Baseboard fan failure detection and indicator control

• SEL interface management

• Sensor Data Record Repository (SDRR) interface management

• SDR/SEL timestamp clock

• Baseboard Field Replaceable Unit (FRU) information interface

• System management watchdog timer

• Periodic SMI timer

• Front panel NMI handling

• Event receiver

• ISA host and IPMB interface management

• Secure mode control, front panel lock/unlock initiation, and video blank and diskette write

protect monitoring and control

• Sensor event initialization agent

• Wake on LAN via Magic Packet

• ACPI Support

• Emergency Management Port (EMP) support

System Security

To help prevent unauthorized entry or use of the system, the system includes a three-position key
lock/switch to permit selected access to drive bays (position is communicated to BMC). The
system also includes server management software that monitors the chassis intrusion switch.

Mechanical Locks and Monitoring

The system includes a chassis intrusion switch. When the access cover is opened, the switch
transmits an alarm signal to the baseboard, where server management software processes the
signal. The system can be programmed to respond to an intrusion by powering down or by locking
the keyboard, for example.

Software Locks via the SSU or BIOS Setup

The SSU 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, the SSU allows you to:

• Enable the keyboard lockout timer so the server requires a password to reactivate the keyboard

and mouse after a specified time-out period of 1 to 120 minutes

• Set and enable administrator and user passwords

• 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

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

Using Passwords

If you set and enable a user password but not an administrator password, enter the user password to
boot the system and run the SSU.

If you set and enable both a user and an administrator password:

• Enter either one to boot the server and enable the keyboard and mouse

• Enter the administrator password to access the SSU or BIOS Setup to change the system

configuration

Secure Mode

Configure and enable the secure boot mode by using the SSU. When secure mode is in effect, you:

• Can boot the system and the OS will run, but you must enter the user password to use the

keyboard or mouse

• Cannot turn off system power or reset the system from the front panel switches
Secure mode has no effect on functions enabled via the Server Manager Module or power control

via the real-time clock (RTC).
Taking the system 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 power off
when secure mode is later removed. However, if the front panel power switch remains depressed
when secure mode is removed, the system will power off.

Summary of Software Security Features

Table 5 lists the software security features and describes what protection each offers. In general,
to enable or set the features listed here, you must run the SSU and go to the Security Menu
(described in this manual on page 41). The table also refers to other SSU menus and to the Setup
utility. For greater detail, see Chapter 3, beginning on page 31.

How to enter secure mode:

Setting and enabling passwords automatically puts the system into secure

mode.

If you set a hot-key combination (through the SSU or Setup), you can secure

the system simply by pressing the key combination. This means you do not

have to wait for the inactivity time-out period. See “Security Menu” on

page 41.

When the system is in secure mode:

The system can boot and run the OS, but mouse and keyboard input is not

accepted until the user password is entered.

At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A,

the system prompts for a password. When the password is entered, the

system boots from CD or diskette and disables the secure mode.

If you have not yet installed a CD-ROM drive, if there is no CD in the drive or

diskette in drive A, the system boots from drive C and automatically goes into

secure mode. All enabled secure mode features go into effect at boot time.

To leave secure mode:

Enter the correct password(s).

password is entered. To set these features, see “Secure Mode Boot” and

“Floppy Write Protect” in “Security Menu,” page 41.

If this protection feature is enabled by the SSU, the power and reset buttons

are disabled when in secure mode.

You can specify and enable an inactivity time-out period of from 1 to

120 minutes. If no keyboard or mouse action occurs for the specified period,

attempted keyboard and mouse input will not be accepted. To set this

feature, see “Secure Mode Timer” in “Security Menu,” page 41.

If video blanking is enabled, the monitor display will go blank until the correct

password(s) is entered. To set this feature, see “Video Blanking” in “Security

Menu,” page 41.

Table 5. Software Security Features

Feature Description

Control access to using
the SSU: set
administrator password

To control access to setting or changing the system configuration, set an

administrator password and enable it through Setup or the SSU.

If both the administrator and user passwords are enabled, either can be used

to boot the system or enable the keyboard and/or mouse, but only the

administrator password allows changes to Setup and the SSU.

Once set, passwords can be disabled by setting the password to a null string

or by changing the Clear Password jumper. See “Security Menu,” page 41;

or, to change a jumper, see “Baseboard Jumpers,” page 151.

during POST, BIOS automatically detects and tests the keyboard, if present,

and displays a message. No entry exists in the SSU for enabling or disabling

a keyboard. Do not plug in a keyboard while power is applied to the system.

The sequence you specify in the Boot Device Priority Submenu (see page 44)

of the SSU’s Boot Menu determines the boot order. If secure mode is

enabled (user password is set), you will be prompted for a password before

the system boots fully. If secure mode is enabled and the “Secure Mode

Boot” option is also enabled, the system boots fully but requires a password

before accepting any keyboard or mouse input.
