Modular high density communications chassis

A modular high density communications chassis, comprising:

• a chassis configured for receiving communications equipment, defined by a first panel, a second panel, and two opposing side panels, forming an access opening and an access mounting opening, opposite the access opening, and at least a second track positioned on the second panel longitudinal to the two opposing side panels, wherein the at least a second track has a first stage access fixing recess and a second stage access fixing recess, whereby the second stage access fixing recess is closer to the access opening than the first stage access fixing recess;
• and
• at least a slidable carrier module, comprising a second module rail on a top side thereof, at least a push-pull tab having an extension portion extending perpendicularly outwardly from a front plane of the at least a slidable carrier module and an assembly portion, assembled to a side of the at least a slidable carrier module, and a snap-fit mechanism, corresponding to the assembly portion, assembled to the side of the at least a slidable carrier module,
• wherein the at least a slidable carrier module is slidably mounted on the at least a second track via the second module rail, and when the at least a slidable carrier module is mounted to the chassis, at least a portion of the extension portion of the push-pull tab extends past a plane of the access opening,
• wherein the at least a push-pull tab is configured to move the snap-fit mechanism, and
• wherein the snap-fit mechanism is configured to secure and release the at least a slidable carrier module in and from a first stage position when corresponding to the first stage access fixing recess, and in and from a second stage position when corresponding to the second stage access fixing recess, via pulling and pushing of the at least a push-pull tab, respectively.
