Rack Or Cabinet Hardware Installation - Dell EMC SD-WAN Edge 3000 Series Installation Manual

NOTE: Coat the one-hole lug with an antioxidant compound before crimping. Also, bring any unplated mating surfaces
to a clean finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from
contamination.
NOTE: The rack installation ears are not suitable for grounding.
Before you install the platform:
1. Cut the user-supplied ground cable to the wanted length. The cable length must facilitate proper operation of the fault interrupt
circuits. Use the shortest cable route allowable.
2. Attach the user-supplied ground lug using M3 screws.
Order a UL-certified GND lug with bracket separately.
3. Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.

Rack or cabinet hardware installation

You may either place the platform on a rack shelf or mount the application directly into a 19" wide, EIA-310- E-compliant rack.
The platform includes two-post rail assemblies.
WARNING: This document is a condensed reference. Read the safety instructions in your
Regulatory information booklet before you begin.
NOTE: The figures in this document are not intended to represent a specific platform.
NOTE: Do not the use the mounted two-post rails 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, and then work to the top. Do not exceed your load rating of the rack.
• 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 maximum ambient temperature of the platform.
• Reduced air flow—Install the equipment in the rack so that the amount of airflow that is 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.
