Abstract
An electronic chassis includes a first card guide attached to the electronic chassis. The first card guide includes a plurality of openings formed therein. The first card guide further includes a channel positioned between each of the plurality of openings to receive a plurality of circuit boards. A first electromagnetic interference (EMI) shielding screen is positioned adjacent the first card guide. An air filter is positioned within the electronic chassis, and is spaced-apart from the EMI shielding screen to allow room air to flow through the air filter and to allow filtered air to be distributed along the plurality of openings.

An electronic chassis apparatus comprising:
- an electronic chassis including a first card guide attached to the electronic chassis, the first card guide including a plurality of openings formed therein, the first card guide further including a plurality of channels to receive a plurality of circuit boards, each of the plurality of channels positioned adjacent to at least one of the plurality of openings, a first electromagnetic interference (EMI) shielding screen having a grid pattern positioned adjacent to the first card guide, the first electromagnetic interference (EMI) shielding screen covering the plurality of openings, and an air filter positioned within the electronic chassis and spaced-apart from the first electromagnetic interference (EMI) shielding screen to allow room air to flow through the air filter and to allow filtered air to be distributed along the plurality of openings.
A method of operating an electronic chassis comprising:
- providing an electronic chassis including a first card guide attached to the electronic chassis, the first card guide including a plurality of openings formed therein, the first card guide further including a plurality of channels to receive a plurality of circuit boards, each of the plurality of channels positioned adjacent to at least one of the plurality of openings, a first electromagnetic interference (EMI) shielding screen having a grid pattern positioned adjacent to the first card guide, the first electromagnetic interference (EMI) shielding screen covering the plurality of openings, and an air filter positioned within the electronic chassis and spaced-apart from the first electromagnetic interference (EMI) shielding screen;
- flowing room air through the air filter;
- and
- distributing filtered air along the plurality of openings.
