Technician Notes
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> WARNING <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Only authorized technicians trained by Compaq should attempt to repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indications of component replacement or printed wiring board modifications may void any warranty.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
To properly ventilate your system, you must provide at least 12 inches (30.48 cm) of clearance at the front and back of the computer.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
The computer is designed to be electrically grounded. To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet only.

Chapter 2. Removal and Replacement Procedures

Chapter 2.0 Introduction
This chapter provides subassembly/module-level removal and replacement procedures for the Compaq ProSignia 300 Server. After completing all necessary removal and replacement procedures, run the DIAGNOSTICS program to verify that all components operate properly.
NOTE: Refer to the support software guide for procedures on using the
Compaq System Configuration utility when installing or removing expansion boards, mass storage devices, and Extended Industry Standard Architecture (EISA) or Peripheral Component Interconnect (PCI) options.
To service the Compaq ProSignia 300 Server, you will need the following:
o Torx T-15 screwdriver
o Ethernet loop back plug
o System Configuration software
o Diagnostics software
o Drive Array Advanced Diagnostics software
Chapter 2.1 Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or micro-circuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage observe the following precautions:
o Transport products in static-safe containers such as conductive tubes,
bags, or boxes.
o Keep electrostatic-sensitive parts in their containers until they arrive
at static-free stations.
o Cover work stations with approved static-dissipating material. Provide a
wrist strap connected to the work surface and properly grounded tools and equipment.
o Keep work area free of non-conductive materials such as ordinary plastic
assembly aids and Styrofoam.
o Always be properly grounded when touching a static sensitive component or
assembly.
o Avoid touching pins, leads or circuitry.
o Always place drives' PCB assembly side down on the foam.
o Use conductive field service tools.
Chapter 2.2 Preparation Procedures
Before beginning any of the removal and replacement procedures, complete the following steps:
1. Turn the server and any peripheral devices off.
2. Disconnect the AC power cord from the AC outlet, then from the system
unit.
3. Disconnect all external peripheral devices from the server.
Chapter 2.3 Side Access Panel/Front Bezel

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
To remove the Side Access Panel
1. Loosen thumb screws (3) on back bezel.
2. Slide side access panel back and then out.
To remove the Front Bezel
1. Remove front bezel retaining screw (1).
2. Push friction tabs up (located underneath bottom edge of bezel) and pull
forward.
3. Pull bezel forward at the middle pressure points shown in figure above.
Chapter 2.4 J Hood
1. Remove side access panel.
2. Unscrew Torx T-15 screws (4) at back panel.

server's components except the system I/O board.
1. Press the retaining latch (A) and swing the air baffle out away from
the chassis.
2. Place a flat bladed screw driver between the fan bracket and the air
baffles hinge as shown (B).
3. Gently pry the hinge pin out of the fan bracket and tilt the air baffle
away from the bracket.

Chapter 2.7 Boards
This section describes how to remove and replace the processor board, memory modules, option boards, and the system board.
Processor Board
1. Remove retaining screw and pull board straight out.
2. Reverse steps for processor board installation.
Memory
1. Remove processor board.
2. Press SIMM connector latches outward (A).
3. Tilt SIMM module forward (B).
4. Lift SIMM module out (C).
5. To replace SIMM module reverse steps.
6. Run Compaq System Configuration Utility if installed memory size has
changed.
The Compaq ProSignia 300 Server comes standard with 16 MB of ECC system memory. Memory can be expanded to a maximum of 208 MB by installing combinations of 4, 8, 16, or 32 MB 60 or 70 ns industry-standard SIMM modules in the six SIMM sockets on the processor board. The following guidelines MUST be followed when installing or replacing memory:
o SIMMs must be installed in matched pairs; for example: two 16 MB modules.
o Install SIMM pairs in banks 1, 2, or 3.
o SIMM modules must be 60 or 70 ns. Do not install 80 ns SIMMs in the server.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Use only JEDEC standard SIMMs. Non-JEDEC SIMMs may adversely affect data integrity.
