Rack Mount Safety Considerations; Readyrails Installation - Dell Z9100-ON Installation Manual

WARNING: This guide 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.
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 and can damage the equipment and possible
personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting 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 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 45°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 back panel facing in the downward position.

ReadyRails installation

The ReadyRails rack mounting system is provided to easily configure your rack for installation of your Z9100–ON system.
You can install the ReadyRails system using the 1U tool-less method or one of three possible 1U tooled methods. The tooled installation
methods include two-post flush mount, two-post center mount, or four-post threaded.
CAUTION: Do not use this method if you need your system to be NEBS Earthquake Z4-compliant.

rail pegs in the back vertical post flange.
The center extractions show how the pegs appear in both the square and nonthreaded round holes.
