AI Technical Summary

Problems solved by technology

When 16 GPU cards are powered on at the same time, the maximum power consumption required is close to 5000W. Coupled with the synchronous power-on of the high-power chips on the motherboard, it is a very big test for the power supply terminals of the entire chassis. The required current will be very large, and the requirements for the power supply terminals are high, which may cause failure to supply power to the PCIE slot
In the prior art, it is only possible to power on all the PCIE slots at the same time when the chassis is powered on, and it is impossible to power on specific PCIE slots according to user needs, and the flexibility of powering on the PCIE slots is low

The device comprises a control module and one or more PCIE power modules; the control module is connected with all the PCIE power modules; each PCIE power module is connected with the corresponding external PCIE slot; the control module is used for sending power supply control signals to the one or more PCIE power modules; each PCIE power module is used for receiving the corresponding power supply control signal sent from the control module and powering on or powering off the PCIE slot to which the PCIE power module is connected according to the power supply control signal. According to the powering-on and powering-off device and method for the PCIE slots and the main board, the flexibility of supplying power to the PCIE slots can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a power on / off device and method for a PCIE slot, and a motherboard. Background technique [0002] With the rapid development of the Internet and the advent of the era of cloud computing, more users hope that servers will have greater technological breakthroughs in the two fields of cloud and artificial intelligence. And products with higher performance can appear in video search, image search, voice search, deep learning, etc. In order to improve the performance of the server, more and more PCIE (Peripheral Component Interface Express, bus and interface standard) slots are integrated on the server, and the number of chips on the server motherboard is also increasing. [0003] In the prior art, the PCIE slot is directly connected to the power supply, and the PCIE slot is directly powered by the power supply. When the server is powered on, the power supply of the ser...
