Rack Mounting an N30xx Switch

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 Dell ReadyRail system is provided for 1U front-rack, and twopost installations. The ReadyRail 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.

•

Rack loading — Overloading or uneven loading of racks may result in shelf or rack failure, causing damage to equipment and possible

personal injury. Stabilize racks in a permanent location before loading begins. Mount components beginning 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 multiple electrical components are installed in

a rack, ensure that the total component power ratings do not exceed 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 room ambient. Use care not to exceed the 45 degrees 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 supply connections other than

direct connections to the branch circuit, for example: use of power strips.

•

Do not mount the product with the rear panel facing in the downward position.

The ReadyRails rack mounting system is provided to easily configure your rack so that you can install your switch.

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).

1U Tool-less Configuration

To install the Dell ReadyRails system using the 1U tool-less configuration with four-post square holes or unthreaded round holes, follow

these steps.

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. To see how the pegs appear in both the square and unthreaded round holes, see Figure 17.

Align and seat the front flange pegs in the holes on the front side of the vertical post.

Repeat this procedure for the second rail.

To remove each rail, pull on the latch release button on each flange ear and unseat each rail.
