Reference will now be made in detail to examples of inventive aspects of the present disclosure which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
According to the present disclosure, a telecommunications chassis configured to house telecommunications equipment in a high density arrangement is provided. As will be discussed in further detail below, the telecommunications chassis is configured with cable management features for managing cables extending to and/or from the telecommunications equipment. In addition, the telecommunications chassis is configured to allow access to all major components of the equipment.
Referring now to FIGS. 1-7, a first embodiment of a telecommunications chassis 10 having features that are examples of inventive aspects in accordance with the principles of the present disclosure is illustrated. Another embodiment of a
telecommunications chassis 100 including features similar to the first embodiment 10 is shown in FIGS. 8-11.
Referring to FIGS. 1-7, the telecommunications chassis 10 defines a top 12, a bottom 14, a front side 16, a rear side 18, a right side 20, and a left side 22. The chassis 10 is configured to removably receive and house telecommunications equipment in a stacked arrangement, wherein the telecommunications equipment are generally stacked in a direction from top 12 to bottom 14.
The depicted chassis 10 includes eight panels 24, each including receptacles 26 for receiving the telecommunications equipment. In the depicted embodiment, each panel 24 includes two columns of receptacles 26 extending in a direction from top 12 to bottom 14. Two of the panels 24 define front faces 28 that are exposed toward the right side 20, two of the panels 24 define front faces 28 that are exposed toward the left side 22, two of the panels 24 define front faces 28 that are exposed toward to the front side 16, and two of the panels 24 define front faces 28 that are exposed toward the rear side 18. According to example embodiments, the types of telecommunications equipment that may be mounted to the chassis 10 may be removable, modular type equipment. Such equipment may include electrical equipment such as digital cross- connect jack modules or cassettes. Such modules may include jacks having RJ-45 profiles, including Cat-5e jacks, or 10-Gig jacks as known in the art. The jack modules may define connection locations (e.g., ports) at the fronts of the modules and connection locations at the rears of the modules.
In the depicted embodiment, each panel 24 of the chassis 10 is configured with twenty receptacles 26 (two columns of ten receptacles 26) for holding twenty modules or cassettes. Thus, in the depicted embodiment, the chassis 10 has the capacity to hold one hundred sixty modules or cassettes, forty at each side (or quadrant) 16, 18, 20, 22 of the chassis 10. Other numbers are possible.
As shown in the diagrammatic view in FIG. 5, each of the panels 24 that make up the pair of panels 24 of a given side or quadrant 16, 18, 20, 22 is configured to pivotably move away from the other panel 24 of the pair. As shown in FIG. 5, the panels 24 are configured to pivot about pivot axes 30. By pivoting a desired panel 24, a technician is able to gain access to components such as connection locations of telecommunications equipment that are located at the rears of the equipment (and at the rear faces 32 of the panels 24) and that otherwise would not be accessible from a peripheral exterior of the chassis 10.
As shown in FIGS. 1-7, the chassis 10 defines a central opening 34 extending therethrough in a direction from the top 12 of the chassis 10 toward the bottom 14 of the chassis 10. The central opening 34 is configured to accommodate cables that extend to and/or from the components at the rears of the equipment. As noted above, by pivoting a desired panel 24 about a pivot axis 30, components or connection locations of telecommunications equipment that are otherwise only accessible from the rear face 32 of a panel 24, the central opening 34, and any cabling therewithin may be accessed.
As illustrated in FIG. 6, the chassis 10 is configured such that it can be rotated about a longitudinal axis 36 extending through the center of the opening 34. According to one example embodiment, the chassis 10 is rotatable 90 degrees in a clockwise direction. In such an embodiment, a technician standing at the front side 16 of the chassis 10 (facing the front faces 28 of the panels 24 at the front side 16) can rotate the chassis 90 degrees in a clockwise direction to access the front faces 28 of panels 24 that are normally positioned on the right side 20 of the chassis 10. Similarly, a technician standing at the rear side 18 of the chassis 10 (facing the front faces 28 of the panels 24 at the rear side 18) can rotate the chassis 90 degrees in a clockwise direction to access the front faces 28 of panels 24 that are normally positioned on the left side 22 of the chassis 10. In this manner, if multiple chassis, similar to chassis 10 of FIGS. 1-7, are located in a telecommunications environment such as a data center, aisles only at the front 16 and the back 18 of the chassis 10 need to be provided and full access to all sides 16, 18, 20, 22 of the chassis 10 are provided by the rotational arrangement of the chassis 10. The rotational arrangement also keeps any cables extending to and/or from the mounted telecommunications equipment generally close to the center of the chassis 10, limiting the need for extensive cable slack.
It should be noted that the rotational arrangement discussed above, including the angle of rotation and the direction of rotation, is simply one example and the chassis 10 can be configured for different angles and different freedoms of movement, depending upon the desired connectivity and cabling arrangement.
Still referring to FIGS. 1-7, the chassis 10 also provides for cable management features around the outer periphery of the chassis 10. Each pair of panels 24 defines a cable channel or trough 38 with an adjacent pair of panels 24 that is located generally 90 degrees therefrom. As shown, each cable trough 38 is defined by a first sidewall 40, a second sidewall 42, and an intermediate wall 44 that connects the first sidewall 40 to the second sidewall 42. As shown, hinges 46 that allow the panels 24 to pivot generally about the pivot axes 30 extend along the centerline 48 of the intermediate wall 44.
When the panels 24 pivot, the first and second sidewalls 40, 42 move toward each other. The spacing provided by the cable trough 38 accommodates the moving panels 24.
The first and second sidewalls 40, 42 defining the cable troughs 38 are defined by panels 24 that are located at sides (i.e., quadrants) that are generally 90 degrees apart. For example, if the first sidewall 40 defining a cable trough 38 is of a panel 24 at the front side 16 of the chassis 10, the second sidewall 42 defining the cable trough 38 is of a panel 24 that may be located at the right side 20 of the chassis 10. In contrast, the intermediate wall 44 defining the trough 38 that extends between the first sidewall 40 and the second sidewall 42 is a shared wall. A first half 50 of the intermediate wall 44 is formed by a first panel 24 and the second half 52 of the intermediate wall 44 is formed by another panel 24 that is located at a side (quadrant) that is generally 90 degrees therefrom.
Cables extending from and/or to the front faces 28 of the panels 24 may be guided through the cable troughs 38. According to one example embodiment, cable management structures 54 in form of cable management rings 56 may be used at locations adjacent the troughs 38 for keeping cables organized within the troughs 38. FIG. 7 is a top view of the chassis 10 illustrating one possible positional layout for the cable management rings 56. The cable management rings 56 may be attached to the first sidewall 40 defining the trough 38, to the second sidewall 42 defining the trough 38, to the intermediate wall 44 defining the trough 38, or to the front faces 28 of the panels 24 adjacent the troughs 38. Other locations are certainly possible. In a preferred embodiment, each row of receptacles 26 is provided with a corresponding row of cable management rings 56.
An example cable management ring 56 that may be suitable for use with the chassis 10, 100 of the present disclosure is shown in isolation in FIG. 12. According to one embodiment, the cable management ring 56 shown in FIG. 12 may be
manufactured out of various types of polymers. The cable management ring 56 includes an upper half 58 that is attached at a first end 60 to a lower half 62. Each of the upper half 58 and the lower half 62 defines a transverse extension 64 (e.g. a flexible flap) at a second end 66. The extensions 64 overlap or intermate to capture a cable passing through the ring 56 between the upper half 58 and the lower half 62. If a cable needs to be inserted into or removed from the cable management ring 56, it is passed through the flexible extensions from the second end 66 thereof. When the cable management rings 56 are mounted to telecommunications structures such as the chassis ends 60.
It should be noted that the cable management ring 56 illustrated in FIGS. 7 and 12 and described above is only one example of a variety of different cable management structures 54 that may be used with the chassis 10, 100 of the present disclosure and other structures are possible.
FIGS. 8-11 illustrate the second embodiment of a chassis 100 having features that are examples of inventive aspects in accordance with the present disclosure. The chassis 100 is similar in construction and operation to the chassis 10 described above and shown in FIGS. 1-7. The chassis 100 defines a slightly different overall shape than the chassis 10 of FIGS. 1-7. The chassis 100 of FIGS. 8-12 defines a larger central opening 134 and larger troughs 138 between the panels 124, defined by deeper first and second sidewalls 140, 142.
It should be noted that, although the chassis 10, 100 of the present disclosure have been described and depicted herein as defining a certain height or including a certain number of receptacles 26, 126 for receiving equipment, the chassis 10, 100 may be configured to a variety of equipment sizes and numbers. According to certain embodiments, the chassis 10, 100 may be manufactured in a certain height or size depending upon the desired connectivity application. According to other embodiments, the chassis 10, 100 may be provided in modular form, wherein similar chassis 10, 100 may be stacked on top of each other to increase the density of the connections. When stacked on top of each other, each chassis 10, 100 may still be configured to rotate individually or the stacked chassis may be provided with a locking arrangement to have the chassis 10, 100 rotate in unison. The same principles could be applied to the pivoting of the panels 24, 124.
Examples of various inventive aspects of the present disclosure have been described herein. It will be appreciated that modifications and equivalents of the disclosed inventive aspects are intended to be included within the broad scope of the present disclosure.
