General Safety
WARNING: Observe the following instructions to help prevent potential for property
damage, personal injury, or death.
• The power supplies in your system may produce high voltages and energy hazards.
Opening or removing covers that are marked with the triangle symbol with a lightning bolt
may expose you to a risk of electric shock. Components inside these compartments should
be serviced only by a trained service technician.
The system may have more than one power supply cable. To reduce the risk of
electrical shock, a trained service technician may need to disconnect all power supply cables
before servicing the system.
Where the system regulatory label has the electric current rating suffixed by (X#),
# = maximum number of power supplies per system.
• Do not operate your equipment with any cover(s) removed.
• The internal components, including memory modules, can become extremely hot during
operation. Allow sufficient time to cool before handling.
• Do not use damaged equipment, including exposed, frayed, or damaged power cords.
• When connecting or disconnecting power to hot-pluggable power supplies:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– Disconnect all sources of power from the system by unplugging all power cables from
the power supplies.
• Do not use the equipment where it can get wet. Protect equipment from liquid intrusion.
If your equipment gets wet, disconnect power to the equipment and to any attached devices.
If the computer is connected to an electrical outlet, turn off the AC power at the
circuit breaker before attempting to remove the power cables from the electrical outlet.
Disconnect any attached devices.
• Do not push any objects into the air vents or openings of the equipment. Doing so can
cause fire or electric shock.
• Do not attempt to service the equipment yourself, except as explained in your
documentation or in instructions otherwise provided to you by the manufacturer.
Always follow installation and service instructions closely.
• If your hardware has a voltage selection switch on the power supply, be sure to set it
for the voltage that most closely matches the AC power available at your location.
