Rack Mounting a N30xx Switch
You may either place the switch on the rack shelf or mount the switch directly
into a 19" wide, EIA-310-E compliant rack (four-post, two-post, or threaded
methods). The Dell ReadyRail system is provided for 1U front-rack, and two-
post installations. The ReadyRail system includes two separately packaged rail
assemblies.
WARNING: This is a condensed reference. Read the safety instructions in your
Safety, Environmental, and Regulatory information booklet before you begin.
NOTE: The illustrations in this document are not intended to represent a specific
switch.
Rack Mounting Safety Considerations
• Rack loading—Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to equipment and possible personal injury.
Stabilize racks in a permanent location before loading begins. Mount
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 multiple electrical components are installed in a rack, ensure
that the total component power ratings do not exceed 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 room
ambient. Use care not to exceed the 45 degrees C 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 supply connections other than
direct connections to the branch circuit, for example: use of power strips.
• Product should not be mounted with the rear panel facing in the
downward position.
