Referring to
The circuit board assemblies 120-1 to 120-n may include the same configurable multi-faceted I/O panels or different configurable multi-faceted I/O panels. A circuit board assembly 120-2 may include a single configurable multi-faceted I/O panel 110-2 or a circuit board assembly 120-1 may include multiple configurable multi-faceted I/O panels 110-1, 10a-1. Configurable multi-faceted I/O panels may also have different lengths relative to the circuit board assemblies. Circuit board assembly 120-3, for example, includes a configurable multi-faceted I/O panel 110-3 that is longer than the configurable multi-faceted I/O panel 110-2 on circuit board assembly 120-2.
As shown in
In some embodiments, the circuit board assemblies 120 may include boards that provide application functionality (e.g., single blade computers, storage blades, network processing and I/O blades) and switch boards that provide switching interconnectivity between the node boards (e.g., fabric switches). The computer system chassis 130 may be an advanced telecommunications computing architecture (Advanced TCA or ATCA) chassis complying with or compatible with, at least in part, PCI Industrial Computer Manufacturers Group (PICMG), Advanced Telecommunications Computing Architecture (ATCA) Base Specification, PICMG 3.0 Rev. 2.0, published Mar. 18, 2005, and/or later versions of the specification (“the ATCA specification”). According to such an embodiment, the circuit board assemblies 120 may be ATCA blades complying with or compatible with, at least in part, the ATCA Specification.
Various other embodiments consistent with the present disclosure may include a chassis and/or circuit boards complying with and/or compatible with technical specifications other than and/or in addition to the ATCA Specification. A configurable multi-faceted I/O panel may also be used, for example, in other types of bladed architectures including, but not limited to, VME, CompactPCI (CPCI), and IBM BladeCenter®. A configurable multi-faceted I/O panel may also be used on other computer or electronic devices that use multiple types of I/O interfaces including, but not limited to, notebook computers, desktop computers, home entertainment products, mobile products (e.g., PDAs, cell phones, MP3 players, DVD/CD players, etc.) and automotive entertainment and communication products. The scope of the present disclosure should not, therefore, be construed as being limited to any particular computer system, device, or form factor.

In one embodiment, the circuit board 322 and face plate 324 may comply with or be compatible with, at least in part, the ATCA specification. In one example, the face plate 324 may be sized with a length to accommodate a circuit board 322 having a size in a range of about 8U (˜355.6 mm)×280 mm. The face plate 324 may also be sized such that the circuit board assembly 320 may be coupled to a backplane in a chassis (e.g., chassis 130 in
The I/O device positioning mechanism 350 may include a user selection member 352 that allows the user to select a desired position of the I/O device positioning mechanism 350. In one embodiment, the I/O device positioning mechanism 350 may be pivotably or rotatably mounted relative to the face plate 324, and the user selection member 352 may be a thumbwheel or other device that allows the user to rotate the I/O device positioning mechanism 350. As shown in
The illustrated embodiment of the I/O device positioning mechanism 350 includes an I/O device support member that may be formed by plates 368, 378 supporting the I/O devices 362, 364, 372, 374 to provide the I/O faces 360, 370. As shown, the connector I/O devices 362, 364 may be mounted to the plate 368 and the display I/O device 372 and LED I/O devices 374 may be mounted to the plate 378. The configurable I/O mechanism 350 may also include end portions 356, 358 coupled to ends of the plates 368, 378. A user selection member 352 (e.g., a thumbwheel) may be coupled to one or both of the end portions 356, 358. The end portions 356, 358 may also support pivot members for pivotably mounting the configurable I/O mechanism 350, as described above. The plates 368, 378, end portions 356, 358 and user selection member 352 may be made of any suitable materials, e.g., PCB materials, metal or plastic, known to those skilled in the art. The I/O devices 362, 364, 372, 374 may be mounted to the plates 368, 378 and/or end portions 356, 358 using any technique known to those skilled in the art.
Examples of connector I/O devices include, but are not limited to, Ethernet connectors, Universal Serial Bus (USB) connectors, Firewire or IEEE 1394 connectors, Small Computer System Interface (SCSI) connectors, PS/2 port connectors, serial port connectors, optical connectors, audio connectors (e.g., channel out, line in, microphone), video connectors (e.g., DVI and S-Video), coaxial connectors, and media card reader connectors (e.g., a CompactFlash® card reader connector). Examples of visual interface devices include displays (e.g., LCD or LED displays) and LED indicators. Other I/O devices may include, but are not limited to, switches, user input keys or buttons (e.g., power or reset buttons), and other user control or input devices.
Different combinations of I/O devices form different I/O interfaces. Although the exemplary embodiment shows one I/O face 360 with all connectors 362, 364 and another I/O face 370 with all visual interface devices 372, 374, various combinations of connectors, visual interface devices, and/or other I/O devices may be used to form different I/O interfaces.
The I/O devices 362, 364, 372, 374 of the configurable multi-faceted I/O panel 310 may be coupled to one or more interconnects 382, 384 that are capable of allowing the configurable multi-faceted I/O panel 310 to move between different positions while maintaining the connection. The interconnects 382, 384 may couple the I/O devices 362, 364, 372, 374 to signal paths and/or conductive paths in the circuit board 322 or directly to electronic components mounted on the circuit board 322. In the exemplary embodiment, the interconnects 382, 384 used to couple the connector I/O devices 362, 364 are flexible film circuits. The flexible film circuits 382, 384 may include a dielectric substrate (e.g., polyimide or epoxy) and conductors (e.g., copper) through the dielectric substrate. One example of a flexible film circuit that may be used is the type available from 3M Corporation. The conductors in the flexible film circuits 382, 384 may be connected to paths in the circuit board 322, for example, through vias or pads extending into the circuit board 322. The I/O devices may also be coupled using other types of interconnects including, but not limited to, discrete wires, ribbon cables, coaxial cables, optical fibers, compression type connectors, mechanical interface connectors, and vertical-cavity surface-emitting lasers (VCSELs).
Although the configurable multi-faceted I/O panel 310 is shown in the exemplary embodiment as only a section of the face plate 324, the I/O panel 310 may extend the entire length of the face plate. Multiple configurable multi-faceted I/O panels (not shown) may also be provided along a single face plate 324. A configurable multi-faceted I/O panel also may be coupled to other structures (e.g., to a computer system chassis) instead of to a circuit board.
The illustrated embodiments show the configurable multi-faceted I/O panel 310 with two possible I/O faces 360, 370 configurable into two possible positions. This embodiment is capable of providing twice the effective I/O panel space, for example, in a standard ATCA blade. The configurable multi-faceted I/O panel 310 may also include additional faces and positions to increase further the number of possible I/O interfaces that may be selected and accessed by a user. The I/O device positioning mechanism 350, for example, may include three or four sides or plates to provide three or four respective I/O faces. Other numbers of sides and I/O faces are also possible. Although the I/O faces are shown as flat sides in the exemplary embodiments, a configurable multi-faceted I/O panel may also include rounded faces. The I/O device positioning mechanism, for example, may be cylindrical or semi-cylindrical with different rounded portions providing different I/O faces.
