Install Rack or Cabinet Hardware
You may either place the switch on the rack shelf or mount the switch directly into a 19" wide, EIA-310-E-compliant rack (four-
post, two-post, or threaded methods).
The ReadyRails system is provided for one 1U front-rack and two-post installations. The ReadyRails system includes two
separately packaged rail assemblies.
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, this 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 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 system 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 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 PSU side facing in the downward position.
Installing the Dell ReadyRails System
The ReadyRails rack mounting system is provided to easily configure your rack for system installation.
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
rear flange rail pegs in the rear vertical post flange. Item 1 of the following illustration and its extractions show how the
pegs appear in both the square and non-threaded round holes.
2
Align and seat the front flange pegs in the holes on the front side of the vertical post. See item 2 in the following
illustration.
3
Repeat this procedure for the second rail.
