RODUCT DESCRIPTION

This chapter describes the model offerings and features of Compaq Deskpro EP Series of Personal Computers.

Compaq Deskpro EP Series of Personal Computers

Compaq Deskpro EP Series of Personal Computers 1-1

1.1 Model Overview

Compaq Deskpro EP Series of Personal Computers ship as either desktop or minitower models. They contain the unique, flexible Compaq ATX chassis, which allows you to easily reconfigure the unit as a minitower by (1) removing the drives from the computer, (2) standing the unit on its side, (3) rotating the drives and bezel blanks 90 degrees, then (4) reinserting the drives into the drive bays.

✎

The Compaq Deskpro EP Series, Intel 440BX chipset models will be referred to in this MSG as 440BX.

The Compaq Deskpro EP Series, Intel 810 chipset models will be referred to in this MSG as 810 or Intel 810.

The Compaq Deskpro EP Series, Intel 810e chipset models will be referred to in this MSG as 810e or Intel 810e.

1-2 Product Description

1.2 System Design

! Desktop models of the Compaq Deskpro EP Series of Personal Computers use an

innovative chassis to house the removable system board, expansion boards, power supply, and mass storage devices.

Internal components are accessible when the access panel is removed.

The front bezel is a multi-part assembly that attaches to the chassis with release

latches. Attached to the back of the front bezel is a subpanel that holds the bezel blanks.

! The system board may be removed from the chassis after the access panel is

removed. Details of the disassembly procedure are found in Chapter 4, “Removal and Replacement Procedures.”

! The drive bays are located in the front of the chassis; there are two 3.5-inch drive

bays for internal hard drives and three 5.25-inch drive bays for accessible mass storage.

The chassis design allows drive installation without the use of rails. Guide screws

installed on each side of the drive ensures its proper alignment within the drive bay. Extra guide screws are provided in the front of the chassis.

! The desktop model of this computer may be converted to a minitower

configuration. See Chapter 4, “Removal and Replacement Procedures,” for additional information and instructions.

Detailed descriptions of the system components are presented in the sections that follow.
