1 Introduction

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

2 Chassis

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.
