Install Rack or Cabinet Hardware

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 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 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
cause damage to 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.

Installing the Dell ReadyRails System

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 (two-post flush mount, two-post center mount, or four-post threaded).
1. With the ReadyRails flange ears facing outward, place one rail between the left and right vertical
posts. Align and seat the back flange rail pegs in the back vertical post flange. In the following
illustration, item 1 and its extractions show how the pegs appear in both the square and nonthreaded
round holes.
