Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
The major design of the shared power circuit of a kind of blade type micro-server that the present embodiment provides is as in figure 2 it is shown, it contrasts
Power supply circuits in Fig. 1, have only to a set of voltage conversion circuit and can realize the power supply to multiple nodes in Fig. 2.Accordingly, originally
The circuit diagram that embodiment proposes is as it is shown on figure 3, mainly include voltage conversion circuit I, voltage conversion circuit II and at least two
AND circuit.The present embodiment explanation as a example by four nodes.
As it is shown on figure 3, the SLP_S3# signal of South Bridge chip output and CPU signal in place are through producing after door on four nodes
Raw PSON signal end as the input of an AND circuit I, the outfan of AND circuit I successively with described DC-to-dc
Translation circuit I and described DC-DC transfer circuit II connects, and the output signal of DC-DC transfer circuit II outfan is divided into
Four tunnels, the SLP_S3# signal of each road signal and a node is as the input signal of AND circuit II, described AND circuit II
Output signal control powering on of each node postorder power circuit (such as CPU, the power supply of the device such as south bridge) respectively, finally realize
Start shooting completely.
Circuit diagram based on Fig. 3, each node power of the present embodiment achieves shared, the such as Fig. 4 of the change on its electrifying timing sequence
Shown in.Wherein SLP_S3# is that the S3 state sent by South Bridge chip enables signal, is in S3 sleep state during low level；
PS_PWROK signal is that power supply exports normal indication signal.During start, as long as any one node presses starting key, phase
The south bridge answering node will send SLP_S3# signal, turns 5V enable signal by 12V and makes 12V turn the work of 5V circuit；5V
After voltage is normal, its controller sends POWER_GOOD signal and drives DC-DC transfer circuit II to work, and passes through
12V turns 3.3V enable signal makes 12V turn the work of 3.3V circuit；After 3.3V voltage is normal, only press the joint of on & off switch
Point just can export PS_PWROK signal.The SLP_S3# signal of PS_PWROK signal and the node pressing on & off switch carry out with
Door, its output signal, as the enable signal of postorder power circuit, controls powering on of postorder power circuit, and final realization is opened completely
Machine.
During shutdown, only when all nodes all press closing key, 12V turns 5V circuit and 12V turns 3.3V circuit and just stops work
Make；As long as otherwise there being a node to be in open state, 12V turns 5V circuit and 12V turns 3.3V circuit and is at duty.
The AND circuit of the present embodiment can be realized by following two kinds of methods:
The most described AND circuit can be by realizing with door chip, and its model is 74LVC1G08.
2. institute's AND circuit is stated and can be made up of the audion of at least two；The base stage of each described triode as signal input part,
The grounded emitter of each described triode, the colelctor electrode of triode described at least two be connected with each other after as signal output part.
As shown in Figure 5.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit, although reference
The present invention has been described in detail by above-described embodiment, those of ordinary skill in the field it is understood that still can to this
Invention detailed description of the invention modify or equivalent, and without departing from spirit and scope of the invention any amendment or etc.
With replacing, it all should be contained in the middle of scope of the presently claimed invention.
