Rack or cabinet hardware installation
You may either place the switch on a 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 EMC 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.
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 specic 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, 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’s load rating.
• Power considerations—Connect only to the power source specied 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 re 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 maximum ambient temperature of the switch.
• Reduced air ow—Install the equipment in the rack so that the amount of airow 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.
ReadyRails system installation
The ReadyRails rack mounting system is provided to easily congure your rack for installation of your S3048–ON switch.
You can install the ReadyRails system using the 1U tool-less method or one of three 1U tooled methods—two-post ush mount, two-post
center mount, or four-post threaded.
1 With the ReadyRails ange ears facing outward, place one rail between the left and right vertical posts.
Align and seat the rear ange rail pegs in the rear vertical post ange. In the following illustration, item 1 and its extractions show how
the pegs appear in both the square and non-threaded round holes.
