Description
Technical field
The present invention relates to a kind of method strengthening mainboard and network interface card compatibility, specifically a kind of method of enhancement service device mainboard and different network interface card compatibility.
Background technology
When being engaged in the design of server, often find that the voltage of large-scale server master board design is a lot.Comprise: before the start that powers on, after normal boot-strap operation, system closedown.For any one state, usually in the process of design, all can have different change-over circuits, not only energy-conservation but also can the maximization of guaranteed efficiency, also preventing board be stuck in the course of work and occurs uncertain factor, causes damage to board.And network interface card required voltage is converted by the supply line of different framework under different on-off state by server master board and power supply.
The power supply conversion stability of network interface card under different conditions is subject to the impact that sequential and weight carry, wherein: sequential is that network interface card weight carries by server master board 12V and P12V co-controlling, depends on network interface card model and network interface card quantity.
If network interface card power is comparatively large or network interface card quantity is more, then network interface card load will weigh, just likely occurs network interface card input voltage to be pulled to low-level possible when realizing network interface card voltage transitions, thus causes the situation that occurs that system closedown is restarted.
Common circuit board of server all can have been arranged in pairs or groups corresponding network interface card, but do not get rid of the reason of other board due to mechanism, Power Management Design, space, application demand etc., do not adopt the design of the fixing network interface card of collocation, and adopting the high-power network interface card of other models or user to configure multiple network interface cards voluntarily, this situation just more easily causes the situation occurring that system closedown is restarted.
In prior art, Figure 1 shows that server master board to be powered transformational relation figure to network interface card, wherein: 12V, P12V and P3V3-AUX3 is turned voltage by server master board, P3V3-AUX3 only powers for network interface card before the start that powers on and after system closedown, and after normal boot-strap, network interface card is powered and turn to be provided by P3V3-AUX2.Figure 2 shows that the logic relation picture that server master board switching on and shutting down signal PS-ON controls by P3V3-AUX3, when P3V3-AUX3 is high level time, PS-ON is low level, now system boot; When P3V3-AUX3 is low level time, PS-ON is high level, and now system default is shutdown.The voltage waveform of P3V3-AUX, P3V3-AUX2, P3V3-AUX3 and Gate in system normal shutdown process is obtained through overtesting, when in system normal shutdown process, Gate voltage falls to 5.4V, the linking that N-MOSQ3 closes to Q4 unlatching existence is about 10.6ms switching time.Can find out from waveform, because of network interface card heavier loads.Therefore, when system closedown, network interface card voltage P3V3-AUX declines very fast, and Q3 close after Q4 open before vacuum time longer, cause Q4 to open moment changing voltage P3V3-AUX3 and be pulled low to 2.93V, exceed specification minimum voltage 3.135V, now PS-ON becomes high level, and system default is shutdown; After output capacitance C1 is full of, P3V3-AUX3 returns to normal voltage, and now PS-ON becomes low level again, and system is thought and received starting-up signal, causes restarting.
Summary of the invention
Technical assignment of the present invention is to provide a kind of enhancement service device mainboard and the method for different network interface card compatibility, solves the problem of restarting after server master board exists system closedown when arranging in pairs or groups the network interface card of different model or varying number.
Technical assignment of the present invention realizes in the following manner, a kind of method of enhancement service device mainboard and different network interface card compatibility, on server master board, by the triggered time of adjustment voltage transitions control signal, shorten voltage transitions convergence time in shutdown process, guarantee that in transfer process, input voltage and output voltage are within normal voltage range of application always.
Concrete steps are:
(1) network interface card of varying number or the different model of, according to server master board arranging in pairs or groups, and the phenomenon of restarting after system closedown, check the voltage waveform in system normal shutdown process;
(2) if find, in shutdown process, the convergence time of voltage transitions is longer, causes the situation occurring dragging down gauge tap machine signal voltage during voltage transitions, then carries out next step;
(3), by shortening in shutdown process, controlling the shut-in time of the metal-oxide-semiconductor of whole conversion line sequential, realizing shortening the voltage transitions convergence time in shutdown process;

A kind of enhancement service device mainboard of the present invention has the following advantages from the method for different network interface card compatibility:
1, by reducing voltage transitions convergence time in shutdown process, so reduce to occur in voltage transitions process drag down input voltage phenomenon;
2, ensure that server master board dissimilar network interface card of arranging in pairs or groups all can realize normal work;
3, user can use multiple network interface cards according to the demand of oneself on server master board simultaneously, expands range of application, meets consumers' demand to a greater extent, reduce R&D costs
4, no matter server master board arranges in pairs or groups individual network interface card of which kind of type or varying number network interface card, server master board can be supported, no longer be subject to the impact of network interface card type and quantity and cause cannot starting shooting or cycle power, such server master board application wider (server master board of network interface card more fixing than collocation requires lower), meets the application demand of different user to a greater extent.
5, by the convergence time of adjustment voltage transitions, can realize under the application scenarios of network interface card centrally connected power supply, on application solutions server master board, all network interface cards all can normally work, can resolution system shutdown time the problem of restarting.
