The present disclosure relates to power interface boards, and more specifically to power interface boards for a server or storage system.
A power interface boards (PIB) provides connections from multiple power supply units (PSUs) to a power distribution board (PDB) or a planar motherboard (MB) to power components of the server or storage system. The PSUs are typically stacked on top of one another to save space in the server or storage system. The PIB has parallel functionality to supply power to the components. The PIB is typically designed in standard heights such as 2 U, 3 U, and 6 U. Proper airflow and ventilation is necessary to maintain the PSUs at their optimal thermal operating condition.
Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “another,” “an,” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
Referring to
The main board 110 can be planar. A plurality of cutouts 115 are defined through the front surface of the main board 110 adjacent to the power interface connectors 120.
Referring also to
The output connector 130 can be substantially parallel or coplanar to the main board 110. The output connector 130 is configured to electrically connect directly or indirectly to a power distribution board (PDB) 300 or a motherboard (not shown) of the server. The output connector 130 can be a gold extension connector formed at the end of the main board 110. The output connector 130 can also be substantially perpendicular to the power interface connectors 120.
In assembly, each PSU 200 is electrically connected directly to a corresponding power interface connector 120, and one PSU 120 is stacked directly above another PSU 120. The output connector is electrically connected directly or indirectly to a PDB 300. The design of the PIB 100 does not require power cables, cable connectors, or ATX power connectors because the PIB 100 is directly mounted to the PDB 300. Furthermore, the output connector 130 is at an end of the main board 110. Therefore, there are no direct barriers to the path of air flowing through the cutouts 115 to the PSUs 200.
Finally, it is to be understood that the above-described embodiments are intended to illustrate rather than limit the present disclosure. Variations may be made to the embodiments without departing from the spirit of the present disclosure as claimed. Elements associated with any of the above embodiments are envisioned to be associated with any other embodiments. The above-described embodiments illustrate the scope of the present disclosure but do not restrict the scope of the present disclosure.
