About This Guide
WARNING: To reduce the risk of personal injury from electric shock and hazardous
energy levels, do not exceed the level of repairs specified in these procedures.
Because of the complexity of the individual boards and subassemblies, do not attempt
to make repairs at the component level or to make modifications to any printed wiring
board. Improper repairs can create conditions that are hazardous.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• 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 7.6 cm (3.0 in.) of
clearance at the front and back of the server.
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.

Removal and Replacement Procedures
This chapter provides subassembly/module-level removal and replacement procedures for the
Compaq ProLiant ML350 Generation 2 server. Run the diagnostics program to be sure that
all components operate properly.
To service the server, you may need a Torx T-15 screwdriver.

Removal and Replacement Procedures
Electrostatic Discharge Information
An electrostatic discharge (ESD) 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. Use 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 that 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 Printed Circuit Board (PCB) assembly-side down.
• Use conductive field service tools.

Symbols on Equipment
These symbols may be located on equipment in areas where hazardous conditions may exist.
WARNING: 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.
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 that 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.
This symbol indicates that the component exceeds the recommended
weight for one individual to handle safely.
Weight in kg
Weight in lb
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.

Removal and Replacement Procedures
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 (ESD) can damage electronic components. Be sure that
you are properly grounded (earthed) before beginning any installation procedure. Refer to
“Electrostatic Discharge Information” earlier in this chapter for more information.
Before removing any serviceable parts, determine whether the part is hot-pluggable or
non-hot-pluggable.
Non-Hot-Pluggable Device
If the device is non-hot-pluggable, the server must be powered down. Non-hot-pluggable
devices in the server include the processor, all boards, memory modules, fans, and drive
cages.
Powering Down the Server
System power in the server does not completely power down when the front panel power
button is pressed. The button toggles between on and standby, rather than on and off. The
standby position removes power from most electronics and the drives, but some internal
circuitry remains active. To completely remove all power from the system, you must
disconnect all power cords from the server.
WARNING: To reduce the risk of injury from electric shock, disconnect all power cords
to completely remove power from the system.
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 when the system unit covers are removed.
To power down the server:
1. Press the power button to toggle to standby. This places the server in standby mode,
thereby disabling the main power supply output and providing auxiliary power to the
server. Standby does not completely disable or remove power from the system.

COMPAQ CONFIDENTIAL Codename: Forge Part Number: 236634-002 Last Saved On: 5/14/02 12:00 PM
2. Be sure that the system LED closest to the right on the front panel is amber and that the
fan noise has stopped.
3. Disconnect the AC power cord from the AC outlet, and then from the server.
4. Disconnect all external peripheral devices from the server.
Rack Stability Warning
For stability and safety, properly positioning the server is critical.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure
that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are connected to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more
than one component is extended for any reason.
