Install the Chassis
To install the S4820T system, Dell Networking recommends completing the installation procedures in the
order presented in this document.
You can install the S4820T switch on a rack shelf or mount it directly into a 19–inch wide, EIA-310-E-
compliant rack (four-post, two-post, or threaded methods). Dell Networking provides the Dell
ReadyRails™ system 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.
NOTE: Always handle the system and its components with care. Avoid dropping the S4820T chassis
or its field replaceable units.
NOTE: For proper ventilation, position the S4820T chassis in an equipment rack (or cabinet) with a
minimum of 5 inches (12.7 cm) of clearance around exhaust vents. The acceptable ambient
temperature ranges are listed in the Technical Specifications section under Environmental
Parameters .
NOTE: The illustrations in this document are not intended to represent a specific switch.
CAUTION: Always wear an electrostatic discharge (ESD)-preventive wrist or heel ground strap
when handling the S4820T and its components. As with all electrical devices of this type, take
necessary safety precautions to prevent injury when installing this system. ESD damage can occur
if components are mishandled.
WARNING: This is a condensed reference. Read the safety instructions in your Safety,
Environmental, and Regulatory information booklet before you begin.
Rack Mounting Safety Considerations
You can install the S4820T switch on a rack shelf or mount it 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 40°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.
