Chassis Feature Summary
Table 2. Chassis Feature Summary
Feature Comment
Power system with r edundancy The 750 watt, 220 VAC autoranging power supplies include integrated
fans for cooling. When the server is configured with three supplies
(2 + 1), the third provides redundancy. The supplies can be replaced—
hot-swapped—without turning off server power. The server requires a
minimum of two power supplies. LEDs on the back of the power supply
indicate power on, failure, and predictive failure.
Server chassis The electrogalvanized metal used in manufacturing the server chassis
minimizes electromagnetic interference (EMI) and radio frequency
interference (RFI).
The peripheral bay provides the interface for 3.5- and 5.25-inch media.
It can support:
• One 5.25-inch IDE CD-ROM drive in the 5.25-inch half-height bay.
(Optional: any IDE or single-ended SCSI device, like a tape drive.)
• Two 3.5-inch wide by 1.0- or 1.6-inch hot-swappable low-voltage
differential SCSI (LVDS) hard disk drives mounted side-by-side in
the 3.5-inch hot-swapping bays. These bays allow hot-swapping of
hard disk drives without shutting down the server.
Ten hot-plug PCI I/O expansion slots (six 33 MHz PCI, four 100 MHz
PCI-X).
The plastic front bezel provides airflow and easy access to drives in the
hot-swapping bays. The removable top covers provide proper airflow
and easy access to components inside the server. Only technically
qualified personnel should remove the server covers.
Cooling system with redundancy Six fans (5 + 1) cool and circulate air through the server. The sixth fan
is redundant. The fans can be replaced—hot-swapped—without
turning off server power. An LED indicator mounted next to each fan
guarantees positive identification of the failed fan.
Integrated power supply fans—two or three—cool and circulate air
through the power supplies and the bottom of the chassis.
Server management Interintegrated circuit bus (I2C) for diagnostic and intrachassis
communication. Interchassis management bus (ICMB) for interchassis
platform management communications.
Real-time clock/calendar (RTC).
Front panel controls and indicators (LEDs).
Basic Input/Output System (BIOS), Power-on Self Test (POST), and
Setup Utility stored in a flash memory device.

Peripherals
The peripheral bay provides the interface for 3.5-inch and 5.25-inch media.
3.5-inch Diskette Drive
The 3.5-inch diskette drive in the 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 peripheral bay contains two hot-swapping bays for two 3.5-inch wide (1.0-inch high or
1.6-inch high) wide/fast-20 SCSI III SCA-type hard drives. The hard drives are externally
accessible at the front of the system and connect to a wide LVDS hot-swap SCSI backplane.
As part of the hot-swap implementation, a drive carrier with an integral heatsink is required. The
drives are mounted in the carrier with four fasteners and the carrier snaps into the chassis with a
locking handle. A single metal EMI shield and plastic door cover the drive bays. A hot-swapping
bay is provided for drives that are 3.5 inches wide and 1.0 or 1.6 inches high. Drives can consume
up to 24 watts of power and must be specified to run at a maximum ambient temperature of
40 °C (104 °F).
5.25-inch Removable Media Device Bay
The peripheral bay has one 5.25-inch half-height bay that is accessible from the front of the
system. This bay is intended to provide space for a tape drive for backup or for another removable
device.
We recommend that you do not use this bay for a hard disk drive, because hard disk drives
generate EMI (increasing ESD susceptibility), and because of inadequate cooling.
18 Chassis Descript ion
Hot-Swap Power Supplies
The chassis can be configured with two or three 750-watt power supplies in a 2 + 1 redundancy
configuration. If you have three supplies installed, you can hot-swap a failed supply without
affecting system functionality. If you have two supplies installed, they must occupy the left and
center bays (as you face the back of the server—see Figure 3 on page 17). Each supply is designed
to minimize EMI and RFI. This system is designed to operate at 100/200 VAC only.
The DC output voltages of each power supply are:
• +3.3 V at 36.0 A max
• +5 V at 36.0 A max (total combined output of +3.3 V and +5.5 V not to exceed 195 W)
• +12 V at 36.0 A with 42.0 A <10ms peak
• +24 V at 100 mA
• -12 V at 1.0 A
• +5 V standby 1.0 A
Each supply docks to a 36-pin connector on the system midplane.
System Cooling
The server contains two independent cooling subsystems:
• The upper system, cooling the front panel, profusion carrier, and I/O carrier
(5 + 1 redundancy)
• The lower system, cooling the memory modules, peripheral bay, and power supplies
(2 + 1 redundancy)
Both subsystems offer redundant cooling capabilities. As shipped from the factory, the minimum
configuration includes six system fans in the upper subsystem and two power supplies (each has an
integrated fan). You can install one additional power supply.
NOTE
✏
All chassis covers must be on the system for proper cooling.

2 Boardset Description
The modular scaleable architecture of the SRPL8 rack server supports symmetrical
multiprocessing (SMP) and a variety of operating systems. The server comes with Peripheral
Component Interconnect (PCI) and Industry Standard Architecture (ISA) buses. ISA buses are
used internally only. The system has no ISA slots or a way for the user to make use of the ISA
bus. The server boardset consists of a set of printed circuit boards:
• Profusion carrier
Processor mezzanine board(s)
Front side bus (FSB) terminator modules
Cache coherency filters
• PCI hot-plug (PHP) I/O carrier
Low-voltage differential SCSI (LVDS) hot-swap disk backplane
I/O riser board
• Two memory modules
• Front panel controller board
• Midplane
The profusion carrier is mounted horizontally toward the front of the chassis, and the PHP I/O
carrier is mounted horizontally towards the rear of the chassis. The carriers plug into connectors
on the midplane mounted between the two carriers. The midplane interconnects the carriers with
the memory modules and power supplies. The front panel board is mounted in front of the
profusion carrier in the same plane. This board provides the user interface, server management,
cooling system control, and power control.

Processor Overview
Each Pentium III Xeon processor is packaged in a single edge contact (S.E.C.) cartridge. The
cartridge includes:
• The processor core with an integrated 32 KB primary (L1) cache
• The secondary (L2) cache
• A thermal plate
• A back cover
Processors used with the SRPL8 server must be:
• 5/12 volts
• 100 MHz FSB
• 1 or 2 MB cache
• Validated by Intel for SRPL8 systems
Each processor implements the MMX™ technology with streaming SMID extensions and
maintains full backward compatibility with 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 one of two processor mezzanine boards through a 330-pin
Slot 2 edge connector (SC330.1). The cartridge is secured to the mezzanine carrier by a retention
bracket. Each mezzanine board connects to the profusion carrier. Depending on configuration,
your system has one to eight processors.
The processor external interface is multiprocessor (MP)-ready and operates at 100 MHz. The
processor contains a local APIC unit for interrupt handling in MP and uniprocessor
(UP) environments.
The L2 cache is located on the same die as the processor core and L1 cache. The cache:
• Is offered in 1 MB and 2 MB configurations
• Is ECC protected
• Operates at the full core clock rate
24 Boardset Description
Memory Overview
Main memory resides on two add-in boards, called memory modules. Each memory module
contains slots for 16 DIMMs and is attached to the profusion carrier through a 300-pin connector
on the midplane. The memory controller supports PC 100-registered SDRAM DIMMs. Various
DIMM sizes are supported, but each DIMM must be at least 128 MB. Memory amounts from
128 MB to 16 GB per module are supported. The ECC used for the memory module is capable of
correcting single-bit errors (SBEs) and detecting 100% of double-bit errors over one code word.
Nibble error detection is also provided.
You can install:
• From 1 to 32 DIMMs (total number of DIMMs for two memory modules)
• Equal number of DIMMs on each memory module (except when only one DIMM is used)
NOTE
✏
When only a single memory module is installed, DIMM sizes on that
module may vary, but when both memory modules are installed, the DIMM
configuration on the two modules should be identical to support memory
interleaving for performance gains.
Depending on how the memory modules are installed, the memory subsystem can operate in two
different modes: interleaved and single-port.
• Interleaved mode (two memory modules installed): The memory modules share a common
address range. One memory module responds to even-numbered cache lines, while the other
responds to odd-numbered cache lines. This configuration offers the highest performance
because it allows the two modules to be used in a balanced fashion, reducing address conflicts.
To operate in interleaved mode, the DIMMs MUST BE INSTALLED IN PAIRS (ONE ON
EACH MODULE) AND IN THE SAME LOCATIONS ON EACH MODULE.
• Single port mode (one memory module installed): The single memory module responds to all
memory addresses. The DIMMs on this single carrier need not be installed in pairs and can be
installed one DIMM at a time.
SRPL8 Server System Product Guide 25
DIMM Installation Sequence
A single carrier will support DIMM population in various configurations (empty sockets included).
However, when fewer than 16 DIMMs are installed on a memory module, the preferred population
order is to start from the lowest J number and populate sequentially to the highest. This
recommendation helps maintain optimal signal integrity and thermal performance.
NOTE
✏
Maximum capacity is limited to 16 GB with one memory module installed.
This increases to 32 GB with two modules.
Some OSs and application programs use base memory while others use both conventional and
extended memory. Examples:
• Base memory: MS-DOS
• 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.

NOTE
DIMM sizes and compatibility: Use DIMMs that have been tested for
compatibility. Contact your sales representative or dealer for a list of
approved DIMMs.

Peripherals
Super I/O Chip
The 37C937 Super I/O 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 left connector (as you look at
the back of the system — see Figure 3 on page 17), port B the right connector. 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 37C937 provides one
IEEE 1284-compatible 25-pin bidirectional EPP (supporting levels 1.7 and 1.9). BIOS
programming of the Super I/O 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 I/O carrier has ten 64-bit PCI buses contained in four PCI segments:
• PCI-A provides for PCI slots 1 and 2 (33 MHz), dual-channel LVDS SCSI controller, video,
and PIIX4E.
The PIIX4E controls communications to IDE, onboard ISA, USB, and Super I/O for
handling the keyboard, mouse, diskette drive, parallel port, and serial ports.
• PCI-B provides for PCI slots 3 through 6 (33 MHz).
• PCI-C provides for slots 7 and 8 (two of the 100 MHz PCI-X, 3.3 V slots).
• PCI-D provides for slots 9 and 10 (the two other 100 MHz PCI-X, 3.3 V slots).
Video
The onboard, integrated ATI Rage XL 64-bit VGA chip contains an SVGA controller that is fully
compatible with legacy video standards. The standard system configuration comes with 8 MB of
onboard SDRAM memory. The video controller supports pixel resolutions of up to 1600 x 1200 at
85 Hz 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 up to 100 Hz.
You cannot 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.
SRPL8 Server System Product Guide 27
SCSI Controller
A QLogic 12160 Ultra 160 SCSI chip provides two 16-bit high-speed SCSI channels. This
high-performance SCSI controller is capable of providing data rates up to 160 MB/sec per channel
in 16-bit operations to ensure maximum data throughput while minimizing PCI bus overhead.
Each channel is 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),
80 MB/sec (40 MHz) (Ultra-2), or 160 MB/sec (40 MHz double clocked) (Ultra 160).
The QLA12160 has its own set of PCI configuration registers and SCSI I/O registers. As a
PCI 2.1 bus master, the controller supports burst data transfers on PCI up to the maximum rate of
132 MB/sec using on-chip buffers.
In the hot-swap SCSI hard drive bay, the system supports up to two 1-inch SCSI hard disk drives.
The 5.25-inch removable media bay supports one SCSI or IDE device (the controller itself
supports more devices, but the 5.25-inch bay can contain a maximum of one device). SCSI
devices do not need to operate at the ultra transfer rate. All drives on the bus must be Ultra 160
(LVD) to run at 160 MB/sec. The 5, 10, and 20 MHz 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
I/O carrier with active terminators.
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 I/O carrier 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 (33 MB/sec using ultra DMA transfers)
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
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 (see security options in “Security Add-In” on page 57). Once
the inactivity (lockout) timer has expired, the keyboard and mouse do not respond until the
previously stored password is entered.
28 Boardset Description
Server Management
Most of the server management features are implemented using three microcontrollers, the
baseboard management controller (BMC) on the I/O carrier, the front panel controller (FPC) on the
front panel board, and the hot-swap controller (HSC) on the LVDS backplane.
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). 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 or during regularly scheduled maintenance. To
retrieve SEL contents, field service personnel use tools such as the SSU SEL Viewer or the
®
Server Control management software.
Intel
The BMC:
• Provides temperature and voltage monitoring
• Monitors processor presence and performs Fault Resilient Booting (FRB) control
• Manages SEL interface
• Manages SDRR interface
