Rack Mounting the 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 ReadyRails™ system is provided for 1U front-rack, and
two-post installations. The ReadyRails system includes two separately
packaged rail assemblies and two rails that are shipped attached to the sides
of the switch.

Rack Mounting Safety Considerations
Rack loading—Overloading or uneven loading of racks may result in shelf
•
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize 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 multiple electrical components are installed 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 40°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 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 rear panel facing in the downward
•
position.
