Rack Mounting Safety Considerations - Dell Networking S3048 Guía De Inicio

CAUTION: Always wear an electrostatic discharge (ESD)-preventive
wrist or heel ground strap when handling the S3048–ON and its
components. As with all electrical devices of this type, take all
necessary safety precautions to prevent injury when installing this
system. ESD damage can occur if components are mishandled.
CAUTION: The S3048–ON contains two power cords. Disconnect
both power cords before servicing.
CAUTION: Only trained and qualified personnel should install this
equipment. Read this guide before installing and powering up the
S3048–ON.

Rack Mounting Safety Considerations

• Rack mounting — You may either place the switch on a rack shelf or
mount the switch directly into a 19" wide, EIA-310-E- compliant rack.
• Rack loading — Overloading or uneven loading of racks may result in shelf
or rack failure, which may damage the equipment and cause personal
injury. Stabilize the racks in a permanent location before loading begins.
Mount the components beginning at the bottom of the rack, then work to
the top. Do not exceed your rack load rating.
• Power considerations — Connect only to the power source specified on
the unit. When you install multiple electrical components in a rack, ensure
that the total component power ratings do not exceed the circuit
capabilities. Overloaded power sources and extension cords present fire
and shock hazards.
• Elevated ambient temperature — If you install the equipment in a closed
rack assembly, the operating temperature of the rack environment may be
greater than the room ambient temperature. Use care not to exceed the
45°C maximum ambient temperature of the switch.
• Reduced air flow — Install the equipment in the rack so that you do not
compromise the amount of airflow required for safe operation of the
equipment.
• Reverse air flow — To ensure cool air intake and to avoid hot air blow out
from the I/O panel, ensure that you have the necessary clearance.
• Reliable earthing — Maintain reliable earthing of rack-mounted
equipment. Pay particular attention to the supply connections other than
the direct connections to the branch circuit; for example, the use of the
power strips.
• Do not mount the equipment with the Utility panel facing in the
downward position.
