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.
