Abstract

Provided are blanking panels and methods of use for preventing the exchange of cold and hot air in an electronics rack having at least one module. The blanking panels comprise a face having a top edge and an oppositely positioned bottom edge; a first planar member extending transversely from the top or bottom edge; and a second planar member that is slidably engaged with the first planar member. The second planar member is configured for parallel movement relative to the first planar member. Further, the first and second planar members are configured to prevent airflow from a superior side of the blanking panel to an inferior side of the blanking panel. Methods of making and use are further provided.

Claims

1. A blanking panel for preventing the exchange of cold and hot air in an electronics rack having at least one module comprising:

a face having a generally rectangular shape defined by a top edge and an oppositely positioned bottom edge, said top edge and bottom edge separated by opposing side edges, wherein the top edge and bottom edge define the long sides, and the side edges define the short sides of the generally rectangular shape;

a first planar member extending transversely from the top or bottom edge; and

a second planar member slidably engaged with the first planar member, the second planar member configured for parallel movement relative to the first planar member, wherein the second planar member comprises a slide track configured to be received in a passage of the first planar member, the slide track extending along a partial length of a side of the second planar member, wherein the second planar member further comprises stopping portions at opposite ends of the slide track, the stopping portions defining a greater width across the second planar member than that of the slide track so as to define the bounds of movement relative to the first planar member,

wherein the first and second planar members are configured to prevent airflow from a superior side of the blanking panel to an inferior side of the blanking panel within an electronics rack configured to receive the blanking panel.

2. The blanking panel of claim 1, wherein the first planar member comprises a contacting surface configured to receive the second planar member, the contacting surface defining a passage.

3. The blanking panel of claim 1, further comprising a third planar member extending transversely from the other of the top or bottom edge and a fourth planar member slidably engaged with the third planar member, the third and fourth planar members extending parallel to the first and second planar members.

4. The blanking panel of claim 3, wherein the first planar member is removable from the face.

5. The blanking panel of claim 1, wherein the blanking panel is placed in the electronics rack adjacent a rear-mounted switch.

6. The blanking panel of claim 1, wherein the blanking panel is movable between a collapsed configuration when the first and second planar members substantially overlap one another and an extended configuration when the second planar member extends beyond the first planar member, the blanking panel extending a greater distance in the extended configuration than in the collapsed configuration.

7. The blanking panel of claim 1, wherein the first planar member includes a first locking member and the second planar member includes a second locking member, the first and second locking members configured to lock the first and second planar members relative to one another.

8. The blanking panel of claim 1, wherein the face comprises oppositely positioned engagement members configured to secure the blanking panel to the electronics rack.

9. The blanking panel of claim 1, wherein the blanking panel is 1 rack unit (RU) in height.

10. The blanking panel of claim 5, wherein the electronics rack comprises a vacant space adjacent the rear-mounted switch.

11. A system for preventing the exchange of cold and hot air in an electronics rack comprising having at least one front-mounted module and at least one rear-mounted module comprising:

an electronics rack adapted to hold a plurality of electronic modules, the electronics rack configured for intake of air through a front side and exhaust of air through a rear side;

a plurality of slots within the rack, each slot configured to receive an electronic module; and

at least one blanking panel comprising;

a face having a generally rectangular shape defined by a top edge and an oppositely positioned bottom edge, said top edge and bottom edge separated by opposing side edges, wherein the top edge and bottom edge define the long sides, and the side edges define the short sides of the generally rectangular shape;

a first planar member extending transversely from the top or bottom edge; and

a second planar member slidably engaged with the first planar member, the second planar member configured for parallel movement relative to the first planar member, wherein the second planar member comprises a slide track configured to be received in a passage of the first planar member, the slide track extending along a partial length of a side of the second planar member, wherein the second planar member further comprises stopping portions at opposite ends of the slide track, the stopping portions defining a greater width across the second planar member than that of the slide track so as to define the bounds of movement relative to the first planar member,

wherein the first and second planar members are configured to prevent airflow from a superior side of the blanking panel to an inferior side of the blanking panel within an electronics rack configured to receive the blanking panel.

12. The system of claim 11, wherein the electronics rack comprises a plurality of electronics modules, at least one of the plurality of modules comprising a rear-mounted switch.

13. The system of claim 12, wherein the electronics rack comprises a vacant space adjacent the rear-mounted switch.

14. The system of claim 11, wherein the slots are 1 RU in height and the module has a height that is in an increment of 1 rack unit (RU).

15. The system of claim 11, wherein the face is attachable to the front side of the electronics rack and the first and second planar members extend toward the rear side of the electronics rack.
