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

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 specic 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 specied 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 airow 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 congure 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 ush 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.
1 Face the ReadyRails ange ears facing outward. Place one rail between the left and right vertical posts. Align and seat the back ange
rail pegs in the back vertical post ange.
The center extractions show how the pegs appear in both the square and nonthreaded round holes.
