Installing The Dell Readyrails System - Dell Networking S3100 Series Getting Started Manual

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.
4. To remove each rail, pull on the latch release button on each flange ear and unseat each rail. See
item 3 in the following illustration.
