DETAILED DESCRIPTION

(13) With reference to FIG. 6, a system 600 according to the present disclosure for mounting electronic devices on a device rack 610 will now be described. The system 600 may enable one or more first electronic devices, e.g. of a first type or according to a first standard (e.g. ANSI), to be mounted on a device rack that is configured to enable second electronic devices, e.g. of a second type or according to a second standard (e.g. ETSI), to be mounted. For example, the system 600 may enable one or more electronic devices following the ANSI standard to be mounted on a device rack following the ETSI standard.

(14) The system 600 comprises the device rack 610 and an adaptor 620 couplable to the device rack 610. The device rack 610 is similar to the device rack 2 described above with reference to FIG. 1 and the features described in relation to the device rack 2 may apply equally to the device rack 610. In particular, the device rack 610 comprises a plurality of rack coupling points 616, such as fastener openings, spaced along one or more coupling surfaces 614 provided at each lateral side of the device rack 610, such that the rack coupling points 616 are arranged in a first plane P 1 of the device rack, e.g. which is parallel with the longitudinal direction D.sub.1 and lateral direction D.sub.2 of the device rack 610. As described with reference to FIG. 1, the rack coupling points 616 may be provided in pairs, such as first, second and third, pairs 616a, 616b, 616c, with one rack coupling point 616 in each pair being provided on each of the lateral sides of the device rack 610, configured to support electronic devices in a horizontal plane. The device rack defines an interior space 618 for receiving electronic devices coupled to the coupling points 616.

(15) The device rack 610 may follow a standard, such as the ETSI standard. Accordingly, the rack may be sized and shaped to enable ETSI standard rack mountable electronic devices to be mounted on the device rack.

(16) Returning briefly to FIGS. 2 and 3, the electronic devices 200, 300, may comprise device mounting brackets 220, 320 coupled to both lateral side surface of the electronic devices for coupling the electronic devices to the device rack. The device mounting brackets may comprise device coupling points 222, 322, e.g. fastener opening. A dimension between the device comping points provided on the device mounting bracket on one lateral side of the electronic device and the device coupling point provided on the device mounting bracket on the opposite lateral side of the electronic device may define a width of the electronic device and may be a standard dimension, such as 19 inches. The dimension may correspond to a dimension between rack coupling points in each pair of rack coupling points in the lateral direction D.sub.2 of the device rack.

(17) In order to mount the electronic devices on the device rack, the device coupling points 222, 322 provided on the mounting brackets 220, 320 on each lateral side of the electronic devices may be aligned with rack coupling points 616 on the coupling surfaces 614 on either lateral side of the device rack, e.g. with one or more pairs of the coupling points 616. Fasteners may then be used to couple the electronic device to the device rack at the coupling points. For example, fasteners, e.g. bolts, may be passed through fastener openings at the device coupling points 222, 322 and the rack coupling points 616.

(18) As depicted, the device mounting brackets 220, 320 may be coupled to the electronic devices at or towards front faces 206, 302 of the device racks and may be arranged such that, when the electronic devices are mounted to the rack coupling points 616 of the device rack, the electronic devices are arranged with a depth dimension of the electronic devices (extending from the front face 206, 302 to the rear face 208, 304 of the electronic device) aligned with the depth dimension D.sub.3 of the device rack. In accordance with the ETSI standard, the device rack be sized to allow electronic devices having a maximum depth of 280 mm to be mounted on the rack.

(19) In the arrangement shown in FIG. 6, the device rack 610 has a width in the lateral direction D.sub.2, between the rack coupling points 616 at either lateral side of the device rack, of 19 inches. However, in other arrangements, the rack may have a different width. For example, the width may correspond to the dimension between the device coupling points 222, 322 provided on the device mounting brackets 220, 320 on either lateral side of the electronic devices that are to be mounted on the device rack.

(20) The adaptor 620 comprises a coupling portion 630, configured for coupling to the device rack 610, and a mounting portion 640 configured for mounting one or more second electronic devices 300, e.g. of a second type or according to a second standard, on the adaptor 620.

(21) The adaptor mounting portion 640 comprises a first mounting surface 642 and a second mounting surface 644. One or more adaptor coupling points 646 are spaced along the first and second mounting surfaces 642, 644 for coupling the second electronic devices to the adaptor. The adaptor coupling points 646 are arranged in a second plane P.sub.2.

(22) The adaptor coupling points 646 are provided in pairs with one coupling point of each pair being provided in each of the first and second mounting surface 642, 644. The first and second mounting surfaces 642, 644 may be spaced apart from one another by a distance corresponding to the distance between the device coupling points 222, 323, provided on the device mounting brackets 220, 320 on either lateral side of the second electronic devices, so that the first electronic devices 650 can be coupled to the first and second mounting surfaces 642, 644 of the adaptor with a width dimension of the second electronic devices extending between the first and second mounting surfaces 642, 644 of the adaptor. Accordingly, when the first electronic devices are mounted on the adaptor, the first electronic devices may be mounted on one or more adaptor device planes P.sub.DA. In other words, the first electronic devices may be generally disposed within, or parallel with, the adaptor device planes P.sub.DA when mounted on the adaptor 620. The adaptor device planes P.sub.DA may be perpendicular to the second plane P.sub.2. As depicted, the adaptor device pane P.sub.DA may be perpendicular to the rack device plane P.sub.DR.

(23) As depicted, the coupling portion 630 may be configured to couple to one or more of the coupling points 616 of the device rack 610 provided on one of the coupling surfaces 614 of the device rack, e.g. provided at one of the one lateral sides of the rack. In some arrangements, the coupling portion 630 may comprise a flange 632 comprising one or more fastener openings 634, which can be arranged to overlap the coupling surface 614 of the rack so that fasteners can be passed though the fastener openings 626 and the coupling points 616 of the device rack to couple the coupling portion 622 of the adaptor to the device rack 610.

(24) In the arrangement shown in FIG. 6, the coupling portion 622 is coupled to the right side of the device rack 610. However, in other arrangements, the adaptor 620 may be coupled to the left side of the device rack 610. As depicted, the adaptor 620 may be configured, e.g. the adaptor coupling points 646 may be arranged relative to the coupling portion 622, such that, when the adaptor 620 is mounted on the device rack, the first and second mounting surfaces 642, 644 are spaced apart from one another in the longitudinal direction D.sub.1 of the device rack. Accordingly, when the first electronic devices 650 are mounted on the adaptor 620 and the adaptor is coupled to the device rack 610, the first electronic devices 650 are arranged with a lateral dimension of the first electronic devices being aligned with the longitudinal direction D.sub.1 of the device rack. Furthermore, a depth dimension of the first electronic devices 650 is aligned, e.g. at least partially aligned, with the lateral direction D.sub.2 of the device rack 610. In this way, first electronic devices 650 having a depth greater than the maximum depth of electronic devices that the device rack is intended to support may be mounted on the device rack 610 and received within the interior space 618 of the device rack. As such, the electronic devices are mounted in a vertical plane. The plane of the planar electronic devices extends vertically and laterally across the width of the device rack.

(25) Referring now to FIGS. 7 and 8, the mounting portion 640 of the adaptor is movable relative to the coupling portion 630 of the adaptor. In particular, the mounting portion 640 is movable relative to the coupling portion between a first position, depicted in FIG. 7, and a second position, depicted in FIG. 8.

(26) When the mounting portion 640 is in the first position relative to the coupling portion 630, the first electronic devices mounted on the adaptor 620 are received within the device rack, e.g. within the interior space 618, of the device rack and the second plane P.sub.2 is at an angle relative to the first plane P.sub.1. Further, as depicted, when the mounting portion 640 is in the first position relative to the coupling portion 630, the adaptor device plane P.sub.DA is parallel with lateral and longitudinal directions D.sub.1, D.sub.2 of the device rack 610.

(27) When the mounting portion 640 is in the second position relative to the coupling portion 630, the first electronic devices mounted on the adaptor 620 may protrude out of the device rack, e.g. out of the interior space 618. The first electronic devices may protrude out by a greater amount than when the mounting portion 640 is in the first position relation to the coupling portion 630. In other words, the first electronic devices mounted on the adaptor 620 may be located at least partially outside of the device rack, for example, fully outside of the footprint of the device rack. Further, when the mounting portion 640 is in the second position relative to the coupling portion 630, the angle between the first plane P.sub.1 and the second plane P.sub.2 may be less than when the mounting portion 640 is in the first position relative to the coupling portion 630. For example, when the mounting portion 640 is in the second position relative to the coupling portion 630, the second plane P.sub.2 may be parallel with the first plane P.sub.1. In this way, access to the first electronic devices, e.g. to connections on the front or rear faces 302, 304 of the first electronic devices, may be improved compared to when the mounting portion 640 is in the first position relative to the coupling portion 630.

(28) In the arrangement shown in FIGS. 6, 7 and 8, the mounting portion 640 is rotatably movable relative to the coupling portion 630. For example, the coupling portion 630 comprises an apparatus, e.g. a hollow cylindrical portion 631, which defines a pivot axis, e.g. vertical pivot axis. For example, the mounting portion 640 is coupled to the coupling portion 630 by a pin 641 extending though the hollow cylindrical portion 631 of the mounting portion. However, in other arrangements, the mounting portion 640 may be slideably movable relative to the coupling portion 630 in addition or as an alternative to being rotatably movable. For example, the mounting portion 640 may be coupled to the coupling portion 630 via one or more rollers. In this way, the mounting portion 640 of the adaptor 620 may be slid into and out of the device rack 610 between the first and second positions.

(29) As depicted in FIGS. 6, 7 and 8, the mounting portion 640 may comprise one or more coupling points 648, such as fastener openings, for enabling the mounting portion 640 to be coupled to one of the coupling surfaces 614 of the device rack 610. For example, the mounting portion 640 may be couplable to the rack coupling points 616 provided on the coupling surface 614 of the device rack 610 at an opposite lateral side of the device rack from the side at which the coupling portion 630 of the adaptor is coupled to the device rack 610. As shown in FIG. 7, when the mounting portion 640 is in the first position relative to the coupling portion 630, the coupling points 648 of the mounting portion may be aligned with the rack coupling points 616 of the coupling surface, such that the mounting portion 640 may be coupled to the coupling surface 614 of the device rack 610 when the mounting portion 640 of the adaptor is in the first position relative to the coupling portion 630.

(30) The mounting portion 640 is rotatably mounted to the standard coupling points of the device rack. This allows the electronic devices, fixed to the mounting portion 640 of the adaptor, to move between a desired first position and orientation within the device rack and a second position in which the electronic devices can be efficiently removed or added to the adaptor. The plane of the electronic devices is vertical, in both the first and second positions. In the first position, the electronic devices extend laterally in the device rack. In the second position, the electronic devices extend at an angle to that lateral direction, e.g. perpendicular to that lateral direction.

(31) As shown in FIG. 8, when the mounting portion 640 is in the second position relative to the coupling portion 630, the coupling points 648 of the mounting portion may be spaced apart from the rack coupling points 616 of the coupling surface 614, such that the mounting portion 640 is not couplable to the coupling surface of the devices rack when the mounting portion 640 of the adaptor is in the second position relative to the coupling portion 630.

(32) With reference to FIGS. 9 and 10, the adaptor may comprise one or more vibration damping portions 900 configured, e.g. shaped, for damping vibrations of the first electronic devices 650 to the device rack 610 and/or of the device rack 610 relative to the first electronic devices 650. The vibration damping portions 900 may be configured, e.g. shaped, to reduce the amplitude of loads transmitted from the first electronic devices 650 to the device rack 610 and/or from the device rack 610 to the first electronic devices 650. Accordingly, one or more of the vibration damping portions 900 may be provided on the adaptor 620 between, e.g. in a load path between, the position(s) on the coupling portion 630 at which that coupling portion is coupled to the device rack and the mounting portion 640, e.g. the adaptor coupling points 646 on the mounting portion. Additionally or alternatively, one or more of the vibration damping portions 900 may be provided on the adaptor between, e.g. in a load path between, the position on the mounting portion at which the mounting portion 640 is couplable to the device rack, e.g. the coupling points 646 of the mounting portion, and the adaptor coupling points 646 on the mounting portion.

(33) The vibration damping portions 900 may be configured to damp vibrations and/or reduce the amplitude of the transmission of loads in first, second and/or third damping directions D.sub.D1, D.sub.D2, D.sub.D3. In particular, the vibration damping portions 900 may comprise one or more first vibration damping portions 902 configured to damp vibrations and/or reduce the transmission of loads in second and third damping directions D.sub.D2, D.sub.D3. Additionally or alternatively, the adaptor may comprise one or more second vibration damping portions 904 configure to damp vibrations and/or reduce the transmission of loads in first and third damping directions D.sub.D1, D.sub.D3.

(34) As shown in FIGS. 6, 7 and 8, the mounting portion 640 of the adaptor 620 may be coupled to the coupling portion 630 at a plurality of locations. For example, when the adaptor 620 is to be coupled to one of the coupling surfaces 614 at a lateral side of the device rack 610, the mounting portion may be coupled to the coupling portion at upper and lower ends of the mounting portion 640, e.g. space apart in the longitudinal direction of the device rack.

(35) In such arrangements, one or more of the vibrations damping portions, e.g. first and second vibrations damping portions, may be provided on the adaptor 620 corresponding to each of the positions at which the mounting portion 640 is coupled to the coupling portion 630. In other words, the vibrations damping portions may be provided in each of the load paths established by the adaptor 620 between the position(s) on the coupling portion 630 at which that coupling portion is coupled to the device rack 610 and the mounting portion 640, e.g. the adaptor coupling points 646 on the mounting portion.

(36) In the arrangements shown, the first and second vibration damping portions 902, 904 are provided on the mounting portion 640 of the adaptor and are configured to damp vibrations and/or reduce the amplitude of loads transmitted in first, second and or third damping directions D.sub.D1, D.sub.D2, D.sub.D3, which are defined relative to the mounting portion 640 of the adaptor. However, in other arrangements, the vibration damping portions may be provided on the coupling portion 630 of the adaptor. In such arrangements, the first, second and third damping directions may be defined relative to the coupling portion of the adaptor. The first, second and third damping directions may be defined such that, when the adaptor is in the first position, the first damping direction DD, is aligned with the longitudinal direction D.sub.1 of the device rack, the second damping direction D.sub.D2 is aligned with a lateral direction D.sub.2 of the device rack and the third damping direction D.sub.D3 is aligned with the third direction D.sub.3 of the device rack.

(37) Referring now to FIG. 10, the adaptor 620 may further comprise one or more third and/or one or more fourth vibration damping portions 906, 908 that are provided on the adaptor 620 between, e.g. in a load path between, the adaptor coupling points 646 on the mounting portion and the coupling points 646 on the mounting portion at which the mounting portion is couplable to the device rack 610. In particular, the adaptor may comprise one or more third vibration damping portions 906 configured, e.g. shaped, to damp vibrations and/or reduce the transmission of loads in the first and third damping directions D.sub.D1, D.sub.D3. Additionally or alternatively, the adaptor 620 may comprise one or more fourth vibration damping portions 908, configured to damp vibrations and/or reduce the transmission of loads in the second and third damping directions D.sub.D2, D.sub.D3.

(38) As depicted in FIGS. 9 and 10, the vibration damping portions 900 may comprise portions of the adaptor 620 having a curved profile in a cross-section in a plane parallel with the directions in which the vibration damping portion is to damp vibrations and/or reduce the transmission of loads.

(39) With reference to FIG. 11, a method 1100 of mounting one or more first electronic devices, e.g. of a first type or according to a first standard, on a device rack system will now be described.

(40) The system comprises a device rack comprising a plurality of rack mounting points for mounting one or more second electronic devices, e.g. of a second type or according to a second standard, on the device rack. The system further comprises an adaptor comprising a coupling portion for coupling to the device rack and a mounting portion comprising one or more adaptor mounting points for mounting the one or more first electronic devices on the adaptor. The mounting portion is movable relative to the coupling portion between a first position and a second position. For example, the system may comprise the system 600 described above with reference to FIGS. 6 to 10.

(41) The plurality of rack mounting points may be arranged in a first plane. The one or more adaptor mounting points may be arranged in a second plane.

(42) The method comprises a first step 1102, at which the adaptor is coupled to the device rack such that, when the mounting portion is in the first position, the first electronic devices mounted on the adaptor are located, e.g. received, within the device rack, e.g. within an interior space of the device rack, and are mounted on one or more planes which extend vertically and laterally relative to the device rack. The adaptor may be coupled to the device rack such that when the mounting portion is in the second position, the first electronic devices mounted on the adaptor are located at least partially outside of the device rack.

(43) The adaptor may be coupled to the device rack such that, when the mounting portion is in the first position, the second plane is at an angle, e.g. is perpendicular, relative to the first plane.

(44) The method 1100 may further comprise a second step 1104, at which one or more first electronic devices are mounted on the adaptor, e.g. to the mounting portion of the adaptor. The method 1100 may further comprise a third step, at which the mounting portion of the adaptor is moved relative to the coupling portion. For example, the mounting portion of the adaptor may be moved from the first position towards the second position or vice versa.
