1Introduction
This specification details the feature set of the Intel®LB440GX 2U rack server chassis, an ATX-form
factor server chassis designed for the Intel®L440GX+ server board.
IntelLB440GX features include:
•2U rack mount chassis (3.46” H x 16.75”W x 28” L)
•One floppy drive
•Two 32-bit/33 MHz PCI slots on the included PCI Riser Card
•Four hot-swap hard drive bays capable of supporting two 1”and two 1.6”LVD SCSI hard drives
•Two system fans
•One 300-Watt PFC PS/2* power supply
2Chassis
The chassis is 3.46 inches high, 16.75 inches wide, and 28 inches long. The rear I/O panel conforms
to the ATX Specification version 2.03, supporting two expansion cards.
2.1 Chassis Color
The primary exterior chassis color will match Intel Color Standard 513505 (dusty beige).
2.2 Front Panel Features
The front panel is pressed SECC with four removable SCSI drive bays, two 1.6” and two 1”. The front
panel also allows for a floppy drive and full-size CD-ROM. The front panel contains a power button
power indicator LED, and hard drive activity LED’s.
2.3 Security
At the chassis level, no security option is provided (no chassis intrusion).
2.4 I/O panel
All input/output connectors are accessible on the rear of the chassis and an ATX 2.03-compatible
cutout is provided for I/O shield installation. A metal I/O shield with appropriate Electromagnetic
Interference (EMI) gasket is installed in the cutout in order to maintain EMI-compliance levels. The
I/O cutout dimensions (measured in inches) are shown in Figure 1 below.

3Chassis Power Subsystem
This chassis uses a single standard PS/2 form factor power supply. Variations may be chosen for
future board sets to satisfy the chassis power, power distribution, thermal performance, acoustic
noise and cost requirements.
The form factor was chosen to optimize the overall chassis dimensions. The typical PS/2 form factor
power supply with a remote enable feature can be used. The remote enable feature permits the
chassis power to be activated from a variety of sources, allowing the implementation of “Wake On
LAN*” (WOL) or other remote management features. The 300-watt PFC (Power Factor Correction)
power supply features a 24-pin main power connector and a 6-pin Auxiliary ATX power connector.
The following table is a brief overview:
ATX 300W Non-PFC 719680-
002 P/S Rating, Maximum Continuous Current
+5 VDC Output26 Amp Max
+12 VDC Output 10 Amp Max
-12 VDC Output 0.5 Amp Max
-5 VDC Output 0.25 Amp Max
+3.3 VDC Output 16 Amp Max
+5 VDC Standby 800mA Max
Output balancing Total combined output power of +3.3V
and +5V shall not exceed 167 W.
AC Line Voltage Autorange
AC Line Frequency 50/60 Hz
AC Input Current 4.6 Amp at 115 VAC 2.3 Amp at 220 VAC
Table 2. Power Supply Output Summary
3.1 Mechanical Outline
The mechanical outline and dimensions of the power supply adhere to the standard PS/2 Form factor.
The approximate dimensions are: 140mm high x 86mm wide x 150mm deep.
3.2 Fan Requirements
The power supply incorporates an 80mm low-acoustic-noise fan to exhaust air. The sound pressure
level is measured at a distance of 0.1 meter from each side of the power supply in a free field. The
worst-case peak value of the measurements shall not exceed 38 dBA at 23°C ±2°C.
Due to the increased output requirements of the 5V standby circuit, power supply thermal margins
are difficult to maintain while the system is in the “off” state. For this reason, the power supply fan
will run at a reduced RPM when the system is off.
3.3 AC Power Line
The power supply is specified to operate from 100-120VAC, 200-240VAC, at 50 or 60Hz and is auto-
ranging. The power supply is tested to meet these voltages, and has been tested (but not specified)
in a configured system at ±10% of the voltage ranges, and similarly ±3Hz on the line input
frequency.
The power supply, in a configured system, is specified to operate without error at full power supply

output load, nominal input voltage, with line source interruptions not to exceed one period of the AC
input power frequency (i.e. 20 milliseconds at 50Hz).
The power supply is not damaged by AC surge ring wave up to 3.0kV/500A. This ring wave is a
100kHz damped oscillatory wave with a specified rise-time for the linear portion of the initial half-
cycle of 0.5µsec. Additionally, the chassis will not be damaged by a unidirectional surge waveform of
up to 1.5kV/3000A, with a 1.2µsec rise time and 50µsec duration. Further details on these
waveforms can be obtained in ANSI/IEEE STD C62.45-1992.

4Chassis Cooling
Two system fans and the power supply fan provide cooling for the processor(s), hard drives, and
add-in cards. Two 80mm system fans are mounted in the middle of the chassis.All chassis fans
provide a single tachometer output for RPM detection that the server board can make available for
server management monitoring and alert functions. Removal of the top cover gives access to the
fans, which then can be easily changed with the system powered down.

5Chassis Peripheral Bays
5.1 3.5" Floppy Drive Bay
The chassis provides for the installation of a 3.5“ floppy drive above the 5.25” CD-ROM drive bay.
Removal of the top cover provides access for replacement of the floppy drive.
5.2 5.25" Drive Bay
The chassis supports one half-height (1.6” high) removable media peripheral devices (typically CD-
ROM). As a guideline based on cooling capabilities, the maximum recommended power per device is
17W. Thermal performance of specific devices must be verified to ensure compliance to the drive
manufacturer’s specifications.
The 5.25" peripherals are removable from the front of the chassis after removal of the top cover.
5.3 LVD SCSI Hot-Swap Drive Bays
The LB440GX 2U rack server chassis supports up to four (two 1” high and two 1.6” high)3.5" LVD
Ultra-2 SCSI hard drives which are accessible from the front of the chassis. Four low-cost SECC
carriers are provided with the chassis to be installed on the hard drives.
Thermal performance of specific hard drives must be verified to ensure compliance to the drive
manufacturer’s specifications. Peripherals must be specified to operate at a maximum ambient
temperature of 50°C.

7Hot-Swap SCSI Subsystem
The IntelLB440GX 2U rack server chassis has two independent, identical hot-swap backplanes.
Each backplane supports two Ultra2 SCSI hot-swappable drives. Two configurable switches on the
back of each backplane (see Figure 11) determine the identification of each drive. The backplanes
are then daisy chained with a standard 68-pin Ultra-2 SCSI cable. The hot-swap SCSI subsystem
supports the following features:
§Hot-swapping of Ultra-2 SCSI drives, that allows connection of SCSI devices while the power
is on.
§Full dual mode LVD operation, compliant with Fast, Ultra and Ultra-2 SCSI bus operation.
7.1 Subsystem Purpose
The IntelLB440GX 2U rack server chassis hot-swap SCSI backplane performs the tasks associated
with hot-swappable SCSI drives. The backplane design allows for:
§Four high density 68 pin connectors for four LVD Ultra-2 compatible SCSI drives
§Active termination on SCSI bus
§Per-drive power control, including automatic slot power down upon drive removal
7.2 Abstract
The IntelLB440GX hot-swap SCSI backplane is made up of the following functional blocks:
§SCSI Bus with Ultra-2 high density LVD 68 pin drive connectors, and active terminators
§SCSI drive power control
§Configuration jumpers

7.3 Hot-Swap Backplane Board Layout
The backplanes reside in the hot-swap drive bay of the IntelLB440GX 2U rack server chassis. Note
this is a passive backplane, which means there is no firmware associated with it (no SAF-TE ASIC).
As a result, server management will not be able to determine the status of each drive.
The following diagram shows the layout of components and connectors on the hot-swap SCSI
backplane printed circuit board.

7.4.1 68 pin LVD high density Hot-Swap Connectors
The IntelLB440GX contains two hot swap backplane boards with two high-density LVD connectors
on each backplane. The connectors provide power and SCSI signals using a single connector. Each
SCSI drive attaches to the backplane using one of these connectors.
7.4.2 SCSI Interface
The SCSI interface on the IntelLB440GX Hot-swap SCSI Backplane provides the required circuitry
between the SCSI bus and the Adaptec controller, which contains the intelligence for the backplane.
The interface consists of an Altera EPLD. After powering on, the Altera EPLD detects the presence of
disks in the slots and powers them on. The SCSI ID configuration of the disks is configured on the
backplanes by using two DIP-switches located on the boards. See section 7.3.1 for the SCSI ID
configuration options.

8Dual-Slot PCI Riser
The IntelLB440GX employs a dual-slot PCI riser, which provides two full-length 32-bit/33Mhz PCI.
The riser is an active riser due to the extra PCI Bus Bridge on the card. The riser resides in PCI slot
number 5 of the IntelL440GX+ server board.
