An electronic system fire containment and suppression apparatus that can include but is not limited to at least one PCB-localized fire containment and suppression structure which can include at least one printed circuit board (PCB) guide rail having at least one intumescent-paint-coated aperture. A communication device, such as a network router or switch, wherein the electronic system fire containment and suppression apparatus is deployed. A method of deploying the electronic system fire containment and suppression apparatus in a communication device. A method of manufacturing the electronic system fire containment and suppression apparatus.

Electronic system fire containment and suppression

An EMI cable passthrough shield for a cable opening in an electronic system housing. The EMI cable passthrough shield includes portions made of an electrically conductive, deformable material having cable passageways to receive cable. A plurality of shields can be stacked in a cable opening of an electronic system housing. The shields can be compressed such that the deformable material completely encloses a cable. An example of a deformable electrically conductive material is an electrically conductive elastomeric material.

EMI cable passthrough shield

The apparatus and method includes a backplane (14) and a plurality of cable connectors (16) arranged orderly on the backplane (14) to which the cables (12) are connected. A plurality of conductive groomer fingers (30) extend generally perpendicularly from the backplane (14) along at least one edge of the backplane (14), where slots of a predetermined width are defined therebetween. Each cable (12) has an EMI termination zone (32) packed in the groomer finger slots to achieve good electrical contact with the groomer fingers (30). A rear cover (34) is used to substantially enclose the backplane (14).

Cable EMI shield termination and enclosure

A cabinet (10) for housing electronic equipment includes a first vertical frame member (12) and a second vertical frame member (14) connected to an upper horizontal frame member (16), a lower horizontal frame member (18), and an intermediate horizontal frame member (20). The upper horizontal frame member (16) includes input/output ports (26) for receiving external cables for passing telecommunications signals. The upper horizontal frame member (16) also includes a recess to slidably receive an air filter assembly. The lower horizontal frame member (18) has reinforced joints for seismic protection. The intermediate horizontal frame member (20) includes integrated ports (40) for internal cable routing and a similar recess (42) for slidably receiving an air filter assembly. A cable tube (24) is connected to the first vertical frame member (12) and the second vertical frame member (14). The cable tube (24) provides cable access to and between the intermediate horizontal frame member (20) and adjacent cabinets while maintaining cable shielding integrity.
