DETAILED DESCRIPTION

[0016] FIGS. 1-3 are top, front and rear views of an exemplary single-board computer cartridge 100 (hereinafter “cartridge 100”) of the present disclosure, and FIG. 4 is a perspective view of a cover 104 of a housing for the cartridge 100. The cartridge 100 can be referred to herein as a consumable unit, or the like. The cartridge 100 includes a base 102 and cover 104 of a housing capable of being detachably interlocked relative to each other to form an enclosure to substantially encase electrical components of the cartridge 100. FIG. 1 shows the cartridge 100 without the cover 104 to illustrate the internal components and/or configuration of the cartridge 100.

[0017] The base 102 includes a front panel 106 defining a front surface of the housing, and further includes a rear surface 108. The base 102 can include a cutout 110 at the rear surface 108 defining an internally recessed area of the housing. The front panel 106 includes mounting rivets 112, 114 on lateral sides of the front panel 106 for detachably securing the cartridge 100 to complementary openings in a rack enclosure. The cover 104 includes a front edge 116 with a U-shaped opening 118 configured to fit behind the front panel 106 of the base 102. The cover 104 includes a rear surface 120 including a cutout 122 defining an internally recessed area complementary to the cutout 110. The cutout 122 includes an opening 124 formed in the walls of the housing, the opening 124 configured to fit over the walls defining the cutout 110 of the base 102.

[0018] The cartridge 100 includes a single-board computer 126 (hereinafter “SBC 126”) disposed on and secured to the base 102. It should be understood that the SBC 126 is provided for illustrative purposes and, in some embodiments, the SBC 126 can include a variety of components. For example, the SBC 126 shown in FIGS. 1-3 can include a display port 128 (e.g., a high-definition multimedia interface (HDMI) port, or the like), and a data output USB port 130. The base 102 includes openings 132, 134 formed in the front panel 106 that align with and at least partially receive the ports 128, 130. The SBC 126 is positioned within the base 102 such that the ports 128, 130 are oriented toward the front of the cartridge 100, allowing the ports 128, 130 to be conveniently accessed from the front of the cartridge 100.

[0019] The cartridge 100 includes a power conversion circuit board 136, a Power-over-Ethernet (PoE) compatible receptacle 138, and a power switch or button 140. The circuit board 136, receptacle 138, and button 140 are electrically interconnected relative to each other and relative to the SBC 126. The power conversion circuit board 136 adapts the SBC 126 to be powered by a PoE cable instead of a dedicated USB power input cable. Specifically, the PoE connector can be electrically connected to the receptacle 138 to provide network data and power to be transmitted over a single cable connection to the cartridge 100. In some embodiments, the power conversion circuit board 136 can include a cooling fan. The power button 140 allows for the entire cartridge 100 to be turned on and off.

[0020] The power button 140 is positioned within a complementary opening 142 formed in the front panel 106 to provide convenient access to the user from the front of the cartridge 100. The receptacle 138 is positioned within the housing to face rearward and through an opening 144 formed in the cutout 110 of the base 102. The rearwardly facing receptacle 138 allow for convenient connection of a PoE connector (e.g., an RJ-45 connector) at the rear of the cartridge 100 when the cartridge 100 is positioned within a rack enclosure. The receptacle 138 is therefore on the opposing side of the cartridge 100 from the ports 128, 130. The cutout 110, 122 in the housing creates a recessed area that provides added protection to the RJ-45 connector and/or cable.

[0021] FIG. 5 is a front view of the cartridge 100 positioned within a rack enclosure 200 (e.g., an LG-X enclosure, or the like). The rack enclosure 200 can include lateral, vertical structural supports 202, 204, and one or more shelf assemblies including top and bottom shelves 206, 208. The shelf assembly can include vertical supports 210 with threaded openings configured to receive the mounting rivets 112, 114 of the cartridge 100. In some embodiments, the rack enclosure 200 can include a front panel or door 212 with a lock 214 for securely covering and protecting the front of the network components disposed on the shelf assembly.

[0022] The housing for the cartridge 100 can be configured and dimensioned per industry standards to be compatible with and fit within the rack enclosure 200, and be detachably secured to the shelf assembly. Specifically, the housing for the cartridge 100 allows for the SBC 126 and electrical components to be enclosed within the footprint of an industry standard form. The rack enclosure 200 can offer both protection and security for the components inside of the cartridge 100, and can enable freer access to front patching (which may need to be serviced often) while restricting access behind the panel or door 212, where components and connections may need to be more secure. In some embodiments, multiple cartridges 100 can be electrically connected or ganged together to increase the processing power (as compared to the processing power of a single SBC 126).

[0023] The exemplary cartridge 100 therefore provides the opportunity for securely and conveniently using SBCs 126 with a single electrical connection for both data and power, and optionally positioning the cartridge 100 within a rack enclosure 200 used in the industry. Such opportunity is provided by modifying the power configuration of the SBC 126 to a PoE connection, and distributing the electrical components within the housing such that display and data ports 128, 130 face towards the front of the cartridge 100 while the PoE receptacle 138 faces towards the rear of the cartridge 100. A separate USB power cable is therefore unnecessary for operating the cartridge 100, and the PoE receptacle allows for the power source to be spaced further from the cartridge 100. The precise opposing orientation of the ports 128, 130 and the receptacle 138 provides the desired functionality of the cartridge 100 in a compact, lightweight form.

[0024] The industry standard sizing of the housing for the cartridge 100 allows for widespread, low-cost rack enclosures 200 (e.g., legacy LG-X enclosures, or the like) to become staging locations for distributed IoT infrastructure, providing a stable, secure, and environmentally-protected platform which necessitates only network PoE cabling to connect. In some embodiments, the cartridge 100 can be used for pure-IoT, non-fiber end users. In some embodiments, the cartridge 100 can be used for a variety of users. The cartridge 100 can enable existing fiber enclosures to add programmable powered devices to their existing enclosures. In some embodiments, a USB interface associated with a computer can provide power for network-programmable lighting, sensors, and/or cameras which could be used to enhance the serviceability and/or security of existing fiber installations, without the need to run additional power cables.

[0025] While exemplary embodiments have been described herein, it is expressly noted that these embodiments should not be construed as limiting, but rather that additions and modifications to what is expressly described herein also are included within the scope of the invention. Moreover, it is to be understood that the features of the various embodiments described herein are not mutually exclusive and can exist in various combinations and permutations, even if such combinations or permutations are not made express herein, without departing from the spirit and scope of the invention.
