Rack Mount Safety Considerations; One-Half U Front-Rack Installation - Dell EMC PowerSwitch S4100-ON Series Installation Manual

WARNING: This document is a condensed reference. Read the safety instructions in your
information booklet before you begin.
NOTE: The illustrations in this document are not intended to represent a specific switch.
NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.

Rack mount safety considerations

• Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, possibly damaging the equipment and causing
personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting at the bottom of the rack,
then work to the top. Do not exceed your rack's 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 installed 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 (113°F) maximum ambient temperature of the switch.
• Reduced air flow—Install the equipment in the rack so that the amount of airflow required for safe operation of the equipment is not
compromised.
• 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, use of power strips.
• Do not mount the equipment with the back panel facing downward.
