Computing devices may utilize option cards. In some cases, new option cards may connect to computing devices via various connectors. The connectors may be disposed on the motherboard of some computing devices. In some cases, the connectors may not be standard for all computing devices. In other words, some computing devices may not include the connectors for the new option card. Some computing devices may not be able to utilize the new option cards, due to lack of non-standard connectors or due to lack of motherboard real estate (for example, where option card connectors are directly connected to the motherboard). For example, an Open Compute Platform (OCP) Network Interface Card (NIC) version 3.0 (OCP NIC 3.0) may connect to a system via a small form factor-technology affiliate-1002 (SFF-TA-1002) connector. In such examples, the SFF-TA-1002 may be directly disposed on the motherboard of a computing device. Further, some computing devices may not include the SFF-TA-1002 connection, thus precluding those computing devices from utilizing the OCP NIC 3.0.

As stated above, the guiderails 104 may accept and guide an option card. In other words, a user may insert an option card into the converter board 100 through the open end of the cutout 110. As the option card is inserted into the converter board 100, the sides of the option card may follow a gap or channel formed by the guiderails 104. In other words, the guiderails 104 may guide the option card to the end connector 106 of the converter board 100. In another example, at least one of the guiderails 104 may include a latch. In such examples, the latch may be utilized for a variety of purposes.
In an example, the latch noted above could be placed in a first position or a locked position. In such positions, the latch could, when there is no option card inserted into the converter board 100, prevent the addition of an option card. The purpose for preventing the addition of a new option card could be to prevent hot plugging of a non-hot pluggable option card. In such examples, inserting a non-hot pluggable option card into an operating, running, or executing computing device could damage the computing device. In a further example of the first position or locked position, the latch could, when there is an option card inserted into the converter board 100, lock the option card in place. The purpose for preventing removal of an option card could be to prevent hot swapping or removal of the option card. In such examples, removing a non-hot swappable option card from an operating, running, or executing computing device could damage the computing device and/or option card.
In another example, the latch noted above could be placed in a second position or an unlocked position. In such positions, the latch could, when there is no option card inserted into the converter board 100, allow the addition of an option card. For example, a user could move the latch to an unlocked position or remove the latch altogether when a computing device is shut down (thus allowing for addition of new components that are not hot pluggable or hot swappable). In another example, the option card may be hot swappable or hot pluggable. In such examples, the user could move the latch to an unlocked position, the user could remove the latch altogether, or the converter board 100 could by default come with the latch in an unlocked position (or removed altogether). In a further example of the second position or unlocked position, the latch could, when there is an option card inserted into the converter board 100, allow the option card to be removed from a computing device. For example, if a non-hot swappable or a non-hot pluggable option card were to experience some issue, a user could move the latch to the unlocked position or remove the latch altogether after the computing device is shut down.
In another example, the option card may be any type of card. For example, the option card may be a NIC, a machine-readable storage medium (such as a solid state drive, flash memory, a hard drive, or any storage related device), a controller, a data processing component, or any other networking component. In another example, the option card may be an OCP NIC 3.0.
In another example, the converter board 100 may include a metal bracket. In such examples, the metal bracket may be attached to the front converter board 100 via fasteners or other means. The metal bracket may add rigidity and/or stability to the converter board 100. The metal bracket may be used to push or pull the converter board 100 into or out of, respectively, a slot, connector, interface, or socket of a computing device. In another example, the metal bracket may include an opening, aperture, or threaded opening to allow for connection of a fastener. In such examples, an option card may include a fastener, such as a thumbscrew. Further, when the option card is fully inserted into converter board 100, the fastener included on the option card may connect to the opening, aperture, or threaded opening, thus securing the option card to the converter board 100.
In another example and as noted above, the two opposing sides may include guiderails 203, 204. In such examples, the guiderails 203, 204 may form a channel or groove. The channel or groove may accept the PCB of an option card. The guiderails 203, 204 may allow for ease of insertion of option card, as well as ensuring proper seating of the option card into the end connector 206. In a further example, at least one of the guiderails 203, 204 may include a latch 212. For example, guiderail 203 may include latch 212. As noted above, latch 212 could be used to prevent insertion of an option card and prevent removal of an option card.
In another example, various apertures 210 or openings may be located on the converter board 200. In such examples, the apertures 210 or openings may be utilized for various purposes. For example, screws or other fasteners may be added through the apertures 210 or openings to fasten a stiffener or bolster plate to the converter board 200, thus increasing the structural integrity of the converter board 200. In another example, screws or fasteners may be added through the apertures 210 or openings to attach the converter board 200 to the bottom tray of a computing device or a motherboard of the computing device.
In another example and as noted above, the option card 302 may be a NIC, a machine-readable storage medium (such as a solid state drive, flash memory, a hard drive, or any storage related device), a controller, a data processing component, or any other networking component. In an example, the option card 302 may include a port. In another example, the option card 302 may include multiple ports. In another example, the option card 302 may include different types of ports. In another example, the option card 302 may not be higher than the highest point of the metal bracket 214. In a further example, the option card 302 height may be set or determined based on various factors, such as the amount of converter boards 300 to be installed in a computing device, the type of converter board 300 (for example, a mezzanine type or a riser type), and/or the type of the option card 302.
At block 502, a user may insert an option card 302 (such as a NIC) into an opening of a converter board 300 (such as a PCIe converter board). The converter board 300 (e.g., the PCIe converter board) may include an opening. The option card 302 (e.g., the MC) may be inserted into the opening of the converter board 300 (e.g., the PCIe converter board). Additionally, the sides of the opening in the converter board 300 (e.g., the PCIe converter board) may include guiderails to ensure ease of installation of the option card 302 (e.g., the NIC), to guide the option card 302 (e.g., the MC) into the converter board 300 (e.g., the PCIe converter board), to ensure proper seating of the connection of the option card 302 (e.g., the NIC) in the end connector 206.
At block 504, a user may fasten, via a thumbscrew 304 or other connector to a metal bracket 214 attached to the converter board (e.g., the PCIe converter board). In an example, the bracket may be compose of a material other than metal, such as plastic. In another example, the thumbscrew 304 may secure the option card 302 (e.g., the NIC) to the metal bracket 214 and secure the option card 302 (e.g., the NIC) in the converter board 300 (e.g., the PCIe converter board).
At block 506, a user may insert the converter board 300 (e.g., the PCIe converter board) into a slot, connector, socket, or interface. In further example, the slot, connector, socket, or interface is a PCIe interface, In another example, the converter board 300 (e.g., the PCIe converter board) may be inserted into the slot, connector, socket, or interface (e.g., a PCIe interface) before the option card 302 (e.g., the NIC) is inserted into the converter board 300 (e.g., the PCIe converter board).
In another example, the option card 302 (e.g., the NIC) may fail or experience an issue. In such examples, a user may replace the option card 302 (e.g., the NIC) due to said failure and/or issue.
In the case that the option card 302 (e.g., the NIC) is hot swappable or hot pluggable, a user may remove the option card 302 (e.g., the NIC) while the computing device or system that the converter board 300 (e.g., the PCIe converter board) is installed in is still operating or running. To remove the option card 302 (e.g., the NIC), a user may move a latch 212 to a second position or unlocked position and then the user may remove the option card 302 (e.g., the NIC). Further, if the new option card to be installed is hot swappable or hot pluggable the new option card may be added at any time after the option card 302 (e.g., the NIC) experiencing the issue has been removed. Further, if the new option card to be installed is not hot swappable or hot pluggable the new option card may be added when the computing device or system that the converter board 300 (e.g., the PCIe converter board) is installed in is still operating or running.
In the case that the option card 302 (e.g., the NIC) is not hot swappable or hot pluggable, a user may remove the option card 302 (e.g., the NIC) when e the computing device or system that the converter board 300 (e.g., the PCIe converter board) is installed in is shut down or powered off. To remove the option card 302 (e.g., the NIC), as noted above, a user may move a latch 212 to a second position or unlocked position and then the user may remove the option card 302 (e.g., the NIC). Further, if the new option card to be installed is hot swappable or hot pluggable the new option card may be added at any time after the option card 302 (e.g., the NIC) experiencing the issue has been removed. Further, if the new option card to be installed is not hot swappable or hot pluggable the new option card may be added when the computing device or system that the converter board 300 (e.g., the PCIe converter board) is installed in is still operating or running.
