Specific embodiment

It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.

In view of the mainboard currently without design plug-and-play circuit, system cannot achieve the warm connection function of PCIE, when need When increasing PCIE device or PCIE device and being needed replacing because of failure or upgrading, needs the running of halt system and close all Power supply just can increase or replace later PCIE device；And have the mainboard of PCIE plug-and-play circuit for design, due to PCIE heat The space and higher cost that circuit needs are plugged, usually only part PCIE slot position band warm connection function on mainboard, and other slots Position does not have warm connection function, when the slot position of not no warm connection function needs to increase PCIE device or PCIE device because of failure or liter Grade and when needing replacing, then want the running of halt system and close all power supplys, just can increase or replace later PCIE device, by This, the utility model proposes a solution, specifically propose a kind of PCIE Riser for increasing warm connection function for mainboard Card.

As shown in Figure 1 to Figure 3, the present embodiment proposes to be the one of the PCIE Riser card that mainboard 90 increases warm connection function End is provided with PCIE slot position 10 for plugging PCIE device 80, the other end be provided with for the PCIE slot on extraneous mainboard 90 The golden finger 20 of position connection, is additionally provided on the PCIE Riser card and sets respectively with the golden finger 20, for plugging PCIE Power-supply controller of electric 30 that standby 80 PCIE slot position 10 connects, programmable logic device 40, the power-supply controller of electric 30 also with it is described Programmable logic device 40 connects.

The switch button 50 connecting with the programming device, the first indicator light are additionally provided on the PCIE Riser card 60, the second indicator light 70.

Wherein, the PCIE slot position 10 for plugging PCIE device 80 defines slot position, the gold hand using standard PCIE Refer to that 20 define golden finger using standard PCIE.The power-supply controller of electric 30 for control 10 out-put supply of PCIE slot position (12V, 3.3V, 3.3VSB) switch.The programmable logic device 40 is communicated with extraneous mainboard 90 by I2C, for controlling the electricity The power supply output state of source controller 30, controls 60 and of the first indicator light at the switch input for receiving the switch button 50 The light on and off state of second indicator light 70, the programmable logic device 40 with the golden finger 20, for plugging PCIE device 80 PCIE slot position 10 between PCIE low speed communication signal transmitted by I2C agreement, the PCIE low speed communication signal mainly has I2C Signal, the signal in place of PCIE device 80 and reset signal etc..

The light color of first indicator light 60 and the second indicator light 70 can be set with experience according to actual needs, example The first indicator light 60 uses red indicating light as will be described, and second indicator light 70 is used green indicator light.

In addition, in order to avoid PCIE device 80 power failure when influence whole system power supply, cause important set The breaking-up of standby and data, in the present embodiment, the power-supply controller of electric 30 is provided with for 80 electricity of mainboard 90 and PCIE device to be isolated The power isolation circuit in source.

The working principle of the present embodiment and usage mode are illustrated below:

It can be the PCIE that mainboard 90 increases warm connection function by the present embodiment proposition before booting or after booting One end of the golden finger 20 of Riser card is inserted into the PCIE slot position on mainboard 90, then PCIE device 80 is inserted into this card PCIE slot position 10 presses switch button 50, and concrete operations process is as follows:

1, when removing the PCIE device 80 on this card:

Switch button 50 is pressed first, waits red indicating light to extinguish, green indicator light lights, then removes on this card PCIE device 80.

2, when replacing the PCIE device 80 on this card:

Switch button 50 is pressed first, waits red indicating light to extinguish, green indicator light lights, then removes on this card Then new PCIE device 80 is inserted into the PCIE slot position 10 of this card by PCIE device 80, press switch button 50, and green is waited to refer to Show that lamp extinguishes, red indicating light lights.

3, when being inserted into PCIE device 80:

This card insertion is entered to the PCIE slot position 10 of mainboard 90 first, green indicator light lights, then new PCIE equipment 80 is inserted The PCIE slot position 10 for entering this card presses switch button 50, and green indicator light is waited to extinguish, and red indicating light lights.

4, when 80 power failure of PCIE device:

When 80 power failure of PCIE device on this card, red indicating light and green indicator light light simultaneously, press out Button 50 is closed, after waiting red indicating light and green indicator light to extinguish, removes the PCIE equipment 80 on this card.

As a result, when system needs to upgrade or PCIE device 80 breaks down, when needing replacing PCIE device 80, by this reality It applies example and proposes to be that the PCIE Riser card of the increase warm connection function of mainboard 90 can close PCIE connection and the electricity of PCIE equipment 80 Source connection, user can remove or be inserted into PCIE device 80 directly from this card, system normal operation not influenced, in addition, working as PCIE When the power failure of equipment 80, power-supply controller of electric 30 can close the power supply of PCIE slot position 10, by its power supply with system every It leaves, will not influence the power supply power supply of system.
