Cable pass-through panel for electronic equipment enclosure
An electronic equipment enclosure includes a frame structure and at least one panel secured to the frame structure. The at least one panel includes one or more panel knockouts arranged therein. Each panel knockout is configured to be removable from the at least one panel to provide a pass-through opening for a cable. The at least one panel further includes a split brush assembly seated in place of a removed one of the one or more panel knockouts.
1. A panel for an electronic equipment enclosure comprising:
a generally planar sheet composed of a metal-based material; and
at least one laser-cut panel knockout arranged interiorly of edges of the generally planar sheet, the at least one laser-cut panel knockout being connected to the generally planar sheet at one or more attachment points and being shaped to include at least one protruding notch along a side thereof;
wherein the generally planar sheet is adapted to be fit atop an electronic equipment enclosure that defines an interior; and
wherein removal of the at least one laser-cut panel knockout, by severing a connection between the at least one laser-cut panel knockout and the generally planar sheet at the one or more attachment points, provides an access opening through the generally planar sheet to the interior of the electronic equipment enclosure, the access opening including an edge having an indentation corresponding to the at least one protruding notch.
2. The panel of claim 1 , wherein the at least one laser-cut panel knockout includes a central portion having curved lateral edges.
3. The panel of claim 1 , wherein the at least one laser-cut panel knockout includes a central portion having stair-stepped lateral edges.
4. The panel of claim 1 , wherein the at least one laser-cut panel knockout includes a central portion having chamfered lateral edges.
5. The panel of claim 1 , wherein the at least one laser-cut panel knockout includes a vent.
6. The panel of claim 1 , wherein a split brush assembly is seated in place of a removed laser-cut panel knockout.
7. The panel of claim 6 , wherein the split brush assembly includes alignment pins inserted within apertures in the generally planar sheet.
8. The panel of claim 1 , wherein the at least one protruding notch is a first protruding notch, and wherein the at least one laser-cut panel knockout is shaped to include a second protruding notch at a side opposite that of the first protruding notch.
9. The panel of claim 8 , wherein the first and second protruding notches are aligned with one another.
10. The panel of claim 8 , wherein the indentation corresponding to the at least one protruding notch is a first indentation, and wherein the edge of the access opening has a second indentation corresponding to the second protruding notch.
11. The panel of claim 10 , wherein, upon removal of the at least one laser-cut knockout, a split brush assembly is attachable at the access opening via snap pins received at the first and second indentations.
12. The panel of claim 1 , wherein the at least one laser-cut panel sub-knockout is arranged interiorly of edges of the at least one laser-cut panel knockout.
13. The panel of claim 1 , wherein the at least one laser-cut panel sub-knockout is connected to the at least one laser-cut panel knockout at one or more sub-knockout attachment points.
14. A panel for an electronic equipment enclosure comprising:
a generally planar sheet composed of a metal-based material;
one or more laser-cut panel knockouts arranged in the generally planar sheet, each laser-cut panel knockout being connected to the generally planar sheet at one or more first attachment points; and
one or more laser-cut panel sub-knockouts arranged in at least one of the one or more laser-cut panel knockouts, each laser-cut panel sub-knockout being connected to the at least one of the one or more laser-cut panel knockouts at one or more second attachment points;
wherein the generally planar sheet is adapted to be fit atop an electronic equipment enclosure that defines an interior; and
wherein removal of a selected one of the one or more laser-cut panel sub-knockouts from a selected one of the one or more laser-cut panel knockouts, by severing a connection between the selected one of the one or more laser-cut panel sub-knockouts and the selected one of the one or more laser-cut panel knockouts at the one or more second attachment points, provides an access opening through the generally planar sheet to the interior of the electronic equipment enclosure.
15. The panel of claim 14 , wherein at least one of the one or more laser-cut panel knockouts includes a central portion having curved lateral edges.
16. The panel of claim 14 , wherein at least one of the one or more laser-cut panel knockouts includes a central portion having stair-stepped lateral edges.
17. The panel of claim 14 , wherein at least one of the one or more laser-cut panel knockouts includes a central portion having chamfered lateral edges.
18. The panel of claim 14 , wherein at least one of the one or more laser-cut panel knockouts includes a vent.
19. The panel of claim 14 , wherein a split brush assembly is seated in place of a removed one of the one or more laser-cut panel knockouts.
20. The panel of claim 19 , wherein the split brush assembly includes alignment pins inserted within apertures in the generally planar sheet.
