Compaq 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.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ If the system has multiple power supplies, disconnect power from the system by
unplugging all power cords from the power supplies.
■ Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
■ Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
CAUTION: To properly ventilate the system, you must provide at least 30.5 cm (12 inches) of
clearance at the front and back of the computer.
CAUTION: The computer is designed to be electrically grounded (earthed). To ensure proper
operation, plug the AC power cord into a properly grounded AC outlet only.
NOTE: Any indications of component replacement or printed wiring board modifications may void any
warranty.

2-2 Compaq ProLiant ML350 Maintenance and Service Guide
Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage, observe the following precautions:
■ Transport products in static-safe containers such as conductive tubes, bags, or boxes.
■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
■ Cover workstations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded (earthed) tools and equipment.
■ Keep work area free of nonconductive materials, such as ordinary plastic assembly aids
and foam packing.
■ Make sure you are always properly grounded (earthed) when touching a static-sensitive
component or assembly.
■ Avoid touching pins, leads, or circuitry.
■ Always place drives with the PCB-assembly-side down.
■ Use conductive field service tools.
Symbols on Equipment
The following symbols may be placed on equipment to indicate the presence of potentially
hazardous conditions:
This symbol in conjunction with any of the following symbols indicates the
presence of a potential hazard. The potential for injury exists if warnings are
not observed. Consult your documentation for specific details.
This symbol indicates the presence of hazardous energy circuits or electric
shock hazards. Refer all servicing to qualified personnel.
WARNING: To reduce the risk of injury from electric shock hazards, do not
open this enclosure. Refer all maintenance, upgrades, and servicing to qualified
personnel.
This symbol indicates the presence of electric shock hazards. The area
contains no user or field serviceable parts. Do not open for any reason.
WARNING: To reduce the risk of injury from electric shock hazards, do not
open this enclosure.
This symbol on an RJ-45 receptacle indicates a Network Interface Connection.
WARNING: To reduce the risk of electric shock, fire, or damage to the
equipment, do not plug telephone or telecommunications connectors into this
receptacle.

Removal and Replacement Procedures 2-3
This symbol indicates the presence of a hot surface or hot component. If this
surface is contacted, the potential for injury exists.
WARNING: To reduce the risk of injury from a hot component, allow the
surface to cool before touching.
These symbols on power supplies or systems indicate the equipment is
supplied by multiple sources of power.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
Weight in kg
Weight in lb
This symbol indicates that the component exceeds the recommended weight
for one individual to handle safely.
WARNING: To reduce the risk of personal injury or damage to the equipment,
observe local occupational health and safety requirements and guidelines for
manual material handling.
CLASS 1 LASER PRODUCT
WARNING: This label or equivalent is located on the surface of the CD-ROM
drive. This label indicates that the product is classified as a CLASS LASER
PRODUCT.

2-4 Compaq ProLiant ML350 Maintenance and Service Guide
Preparation Procedures
WARNING: Only authorized technicians trained by Compaq should attempt to repair this
equipment. 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.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded (earthed) before beginning any installation procedure. See “Electrostatic
Discharge” earlier in this chapter for more information.
Before beginning any removal and replacement procedure for non-hot-plug devices:
1. Power down the ProLiant ML350 server and any peripheral devices.
2. Disconnect the AC power cord from the AC outlet, and then disconnect from the server.
3. Disconnect all external peripheral devices from the server.
NOTE: If you have installed a rack upgrade kit, you must remove the ProLiant ML350 server from the
rack and place it on a sturdy table or workbench. Refer to the Compaq ProLiant ML350 Setup and
Installation Guide for instructions.
Rack Warnings
WARNING: To reduce the risk of personal injury or damage to the equipment:
■ Always load the heaviest item first, and load the rack from the bottom up. This step makes
the rack “bottom-heavy” and helps prevent the rack from becoming unstable.
■ The bottom stabilizers on the equipment must be fully extended. Be sure that the
equipment is properly supported/braced when installing options and cards.
■ Extend only one component at a time. A rack may become unstable if more than one
component is extended for any reason. Be sure that the rack is adequately stabilized
before extending a component outside the rack.
■ Before beginning work on the rack, be sure that the leveling jacks are extended to the
floor, that the full weight of the rack rests on the level floor, and that either stabilizers are
installed or multiple racks are coupled for stability.
■ Because the rack allows you to stack computer components on a vertical rather than
horizontal plane, you must take precautions to provide for rack stability and safety and to
protect both personnel and property. Heed all cautions and warnings in the installation
instructions that come with the server.
■ Tipping can cause injury or death.
WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not
overload the AC supply branch circuit that provides power to the rack.

Removal and Replacement Procedures 2-5
Server Warnings and Precautions
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching them.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure.
CAUTION: The server must always be operated with system unit covers on. Proper cooling is
not achieved if the system unit covers are removed.

2-6 Compaq ProLiant ML350 Maintenance and Service Guide
Front Bezel Door
CAUTION: Before removing the front bezel door, make sure that the server is powered down,
all cables are disconnected from the back of the server, and the power cord is disconnected
from the grounded (earthed) AC outlet.
To remove the front bezel door:
1. Complete the preparation procedures. See “Preparation Procedures” earlier in this chapter.
2. If the keylock is locked, unlock using the included key (1).
3. Open the front bezel door fully to the right (2).
4. Lift the bezel door upward (3), and then away from the chassis.

Figure 2-1. Removing the front bezel door
Reverse steps 1 through 4 to replace the front bezel door.
NOTE: When replacing the front bezel door, ensure that the bottom hinge points are properly placed in the chassis
before rotating the front bezel door back into its original position.
