Embodiment
Technical scheme is further illustrated below in conjunction with Figure of description and specific embodiment.It should be appreciated that this
The specific embodiment of place description is not intended to limit the present invention only to explain the present invention.
The mentality of designing of the present invention is as follows：
1), the secondary power supply plate hot plug wafer damage situation fed back according to computer room staff, is found by analysis, when
The hot plug chip power supply voltage of secondary power supply plate can produce larger fluctuation when heat inserts node；
2), according to the situation of voltage pulsation, the reason for analysis causes wafer damage, found by capturing waveform when heat inserts dynamic
When making too fast, 12V voltage pulsations can be very big, so as to cause wafer damage；
3) 12V fluctuates situation when, being inserted according to heat, selects suitable capacitor's capacity, it is ensured that 12V is being transferred to hot plug chip
When be burning voltage, it is ensured that meet current design needs.
Therefore, in the hot plug design on server board, filtering need to be taken to protect the supply voltage of hot plug chip
Shield measure, it is ensured that the slotting moment supply voltage of heat does not have too great fluctuation process.
Fig. 1 shows hot plug chip operation schematic diagram in the prior art.
As shown in figure 1, illustrate for RACK servers construction for electricity in the prior art, including copper bar, hot plug chip, heat are inserted
MOS is pulled out, the power supply source of all nodes both is from copper bar 12V, and each node passes through the hot plug chip pair of secondary power supply plate
Voltage is controlled conversion, exports to mainboard, hard disk backboard etc., to be powered to different pieces such as CPU, hard disk, internal memories, i.e., each
The input voltage that node is powered is by hot plug chip controls.Wherein so that hot plug chip being capable of normal work on secondary power supply plate
The supply voltage of work also comes from copper bar 12V.
When node inserts copper bar, 12V voltages will drive hot plug chip to start working, and hot plug chip is by sending
MOS switch signal is embodied as the 12V voltage outputs and disconnection that rear class is powered.
When staff carries out on-line maintenance to node, when node is inserted in rack, secondary power supply plate and copper bar are contacted
