Warning Statements Chapter 5 Specifications, Compliance, and Regulatory Statements
PN 200972-001 Rev B 41
• To disconnect power from the server, disconnect all power cables from all power supplies.
(If you only disconnect one hot-swappable power supply, the system will automatically
switch to a redundant one.)
• The power supplies in the server may produce high voltages and potential energy hazards. By
opening the cover of the server you may be exposed to a risk of electric shock. The components
inside the server housing should only be serviced by a trained service technician.
• Inside the housing, the power supply may have more than one power supply cable. To reduce
the risk of electric shock, a trained service technician may need to disconnect all power supply
cables before servicing the system.
• The server should not be operated with the cover removed.
• Components inside the server housing may become extremely hot during normal operations.
These components include the memory and CPU modules. Allow sufficient time for
components to cool before handling.
• The server should not be operated in environments that can get wet. Protect the server at all
times from liquid intrusion.
• If your server gets wet, turn off the AC power at the circuit breaker before attempting to remove
the power cables from the electrical outlet. Then disconnect power to the equipment and to any
attached devices.
• Avoid obstructing the air vents on the server or pushing objects into the openings. This could
lead to fire or electric shock.
CAUTION To prevent hardware damage or loss of data, observe the following precautions:
• Follow installation instructions carefully.
• Do not attempt to service the equipment yourself. The server should be serviced by a trained
service technician.
• You should operate this equipment from the type of external power source indicated on the
electrical ratings label.
• Wait 30 seconds after turning off the equipment before removing a component from the system
or disconnecting a peripheral device from the server.
• Always leave at least 4 inches (10.2cm) of physical clearance on all vented sides of the server.
This permits the airflow required for proper ventilation.
• Avoid placing equipment too close together such that it is subject to re-circulated (pre-heated)
air. Avoid placing equipment too close to an server or exhaust vent.
• Ensure that cables are connected to the server without stress and that nothing rests on the cables.
• If the equipment is located in a rack, move it with caution. Ensure that all casters and/or
stabilizers are firmly connected. While moving the equipment, avoid uneven surfaces and
sudden stops.
• Do not place other equipment, monitors, or other devices on top of the server.
• To protect the server from fluctuations in electrical power, use a surge suppressor, line
conditioner or uninterruptible power supply (UPS).
