Abstract

A ventilation assembly for an electronic equipment enclosure. The ventilation assembly includes a housing having at least one ventilation port, and a cover movable between an open position and a closed position. The cover is positioned over the ventilation port when the cover is in the closed position. The ventilation assembly further includes at least one electromagnet for selectively securing the cover in the closed position.

Claims

1. An outdoor telecommunications equipment enclosure comprising a housing defining at least one exhaust port;

at least one fan positioned in the housing;

a cover movable between an open position and a closed position, the cover positioned over the exhaust port when the cover is in the closed position; and

at least one electromagnet for selectively securing the cover in the closed position.

2. The equipment enclosure of claim 1 further comprising a controller for energizing one of the electromagnet and the fan when the other of the electromagnet and the fan is de-energized.

3. The equipment enclosure of claim 2 further comprising a seal positioned on one of the housing and the cover, the seal surrounding the exhaust port when the cover is in the closed position.

4. The equipment enclosure of claim 3 wherein the electromagnet is mounted on the housing.

5. The equipment enclosure of claim 4 wherein the fan is adapted to at least partially open the cover when the fan is energized.

6. A method for selectively covering an exhaust port of an outdoor telecommunications equipment enclosure having an electromagnet and an exhaust port cover, the method comprising energizing the electromagnet to secure the exhaust port cover in a closed position with the exhaust port cover positioned over the exhaust port.

7. The method of claim 6 further comprising de-energizing a fan prior to or when energizing the electromagnet.

8. The method of claim 6 further comprising de-energizing the electromagnet to release the exhaust port cover from the closed position.

9. The method of claim 8 further comprising energizing a fan when or after de-energizing the electromagnet.

10. The method of claim 6 further comprising attaching the electromagnet to one of the enclosure and the exhaust port cover.
