Compaq Technician Notes
WARNING: To reduce the risk of personal injury from electric shock and hazardous energy
levels, do not exceed the level of repair 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 could
create conditions that are hazardous.
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.
IMPORTANT: Any indications of component replacement or printed wiring board modifications may void
any warranty.
Rack Stability
CAUTION: This unit is designed to be electrically grounded. To ensure proper operation, plug
the AC power cord into a properly grounded (earthed) AC outlet only.
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 attached 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.

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 properly grounded (earthed) when touching a static-sensitive
component or assembly.
■ Avoid touching pins, leads, or circuitry.
■ Always place drives PCB assembly-side down.
■ Use nonconductive field service tools.

2-4 Compaq ProLiant ML570 Maintenance and Service Guide
Preparation Procedures
The system power in the ProLiant ML570 server does not completely power down with the
front panel Power On/Standby switch. The switch toggles between On and Standby, rather than
On and Off. The Standby position removes power from most electronics and the drives, but
portions of the power supply and some internal circuitry remain active. To completely remove
all power from the system, you must disconnect all power cords from the server. For more
information about removing power from the system, see “Powering Down the Server” later in
this chapter. See “Server Warnings and Precautions” later in this chapter for further safety
information.
IMPORTANT: Before beginning to remove any serviceable part, determine whether the part is
hot-pluggable or non-hot-pluggable. Hot-pluggable devices in the ProLiant ML570 server include SCSI
hard drives, fans, and power supplies.
Hot-Pluggable Parts
If the part is hot-pluggable, do not perform a power shutdown of the server. The access panel
can be removed without causing system shutdown. Hot-pluggable devices in the
ProLiant ML570 server includes Wide Ultra2 and Ultra3 SCSI hard drives, some expansion
boards, fans, and power supplies.
IMPORTANT: It is not necessary to power down the server to replace hot-pluggable devices such as
power supplies, fans, or PCI Hot Plug boards when they are not in active use.
Non-Hot-Pluggable Parts
If the part is non-hot-pluggable, the server must be shut down. Non-hot-pluggable parts include
the processors, some expansion boards, DIMMs, and drive cages. See “Powering Down the
Server” later in this chapter for complete powering down instructions.
WARNING: To reduce the risk of personal injury or damage to the equipment, the installation
of options other than hot-pluggable power devices should be performed only by individuals who
are qualified in servicing computer equipment and trained to deal with products capable of
producing hazardous energy levels.
WARNING: To reduce the risk of personal injury or damage to the equipment when moving the
server, be sure that:

Rack Warnings
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 attached to the rack if it is a single-rack installation.
■ The racks are coupled 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.
■ You are careful when pressing the component rail release latches and sliding the
component into the rack. The slide rails could pinch your fingertips.
■ You load the rack from the bottom up and load the heaviest item into the rack first.
■ You do not attempt to move equipment racks without adequate assistance due to their
height and weight.
■ You do not attempt to move an equipment rack on an incline that is greater than
10 degrees from horizontal.
■ You do not attempt to move a fully loaded equipment rack. Remove equipment from the
rack before moving the rack.

Removal and Replacement Procedures 2-7
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ The installation of internal options and routine maintenance and service of this product
should be performed by individuals who are knowledgeable about the procedures,
precautions, and hazards associated with equipment containing hazardous energy levels.
■ Allow the product to cool before removing covers and touching internal components.
■ Do not use conductive tools that could bridge live parts.
■ Remove all watches, rings, or loose jewelry when working in hot-plug areas of an
energized server.
■ Understand the hot-plug access panel provides access to hazardous energy circuits.
■ Understand the panel should remain locked during normal operation.
-Or-
Install the server in a controlled access location where only qualified personnel have
access to the server.
■ Power down the equipment and disconnect all AC power cords before removing any
access covers for non-hot-pluggable areas.
■ Do not replace non-hot-pluggable components while power is applied to the product. First,
shut down the product and disconnect all AC power cords.
■ Do not exceed the level of repair specified in the procedures in the product documentation.
All troubleshooting and repair procedures are detailed to allow only subassembly or
module-level repair. 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 a safety hazard.
■ Verify that the AC power supply branch circuit that provides power to the rack is not
overloaded. Maintaining a low electric current draw reduces the risk of personal injury, fire,
or damage to the equipment. The total rack load should not exceed 80 percent of the
branch circuit rating. Consult the electrical authority having jurisdiction over your facility for
wiring and installation requirements.
■ Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord
by the plug.
■ 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: The ProLiant ML570 server must always operate with the system unit covers and
air baffles in place. Proper cooling cannot be achieved if the system unit covers or air baffles
are removed for extended periods.
IMPORTANT: The installation of options and servicing of this product must be performed by individuals
who are knowledgeable of the procedures, precautions, and hazards associated with equipment
containing hazardous energy circuits.
