Description
Technical field
The present invention relates to a kind of hot swap power-on system and method, hot swap power-on system and method in especially a kind of modularized equipment.
Background technology
Modularization is meant the performance difference but has interface, the dimensional standardization of the equipment of certain common ground on function or the purposes that these equipment just are referred to as module.Be used for that module is placed and fixing slot, be used to realize the connector that interconnects between the module etc., formed modular chassis, the equipment that modular chassis and the module combinations in cabinet form is referred to as modularized equipment.
Modular chassis, topmost several functions are respectively: interconnecting between the power supply of module, placement, the fixing and module.Generally can comprise one in the modular chassis and be used to realize interconnecting and the backboard of module for power supply between the module, backboard is a printed circuit board, be connected with module by some connectors, we claim that these connectors are connector, connector is divided into signal and control connector and power connector, power connector realization module is connected with power supply, and the general pins number is less, can bear big electric current.Generally all connect between backboard and the module, and, can realize each connector pin being interconnected, thereby realize interconnecting between the module according to certain rule by the connecting line on the backboard by a plurality of connectors.Connector generally is divided into two parts, promptly normal male M and the female F that says, male M and female F generally are matching used, because the relation of profile and structure is used male mostly, and is used female on the backboard mostly on the module, also has a lot of pins on the connector, these pins are exactly the carrier of information interaction between module and the backboard, and each pin all can have corresponding signal definition, and the signal definition of the corresponding pin on male M and the female F generally is consistent.
With a kind of modularized equipment one modular switch is example, and the module in it generally is divided into administration module and business module, and administration module is the core of whole modular switch, must have at least one administration module in the time of system works; Business module is realized some business function that the user needs, and its work and configuration etc. need be accepted the management and the domination of administration module, and business module can plug at any time.As a kind of basic communications facility, in order to guarantee the modular switch non-stop run, when inserting and extracting business module, all can not cut off the power supply, and can not influence the operate as normal of other modules, the design of module and modular chassis all needs to support hot plug in other words.Say that simply hot plug is exactly a plug-in module under the situation of equipment energising work, realize that hot plug needs special circuit support.
Fig. 1 has provided the structural representation of existing hot swap power-on system, comprises backboard, hot plug control circuit, power consumption device, the business module of a hot plug of expression in the whole frame of broken lines.As seen from the figure, this hot plug control circuit comprises 3 important pins at least: receive the pin Vin of backboard power supply signal, power supply signal is exported to the pin Vout and the enable signal pin EN of power consumption device; Whether enable signal is used for control module and powers on, and normally high level is effective, and when promptly enabling to high level, pin Vout exports to the power consumption device with the power source voltage that pin Vin receives, and then this hot plug module is powered on; And when enable signal was in low level, pin Vout can not give the power consumption device of this hot plug module by output voltage, thereby this hot plug module is powered on; Therefore enable signal pin EN is equivalent to a control switch, controlling between pin Vin and the pin Vout connection with close.
What Fig. 1 adopted is the mode that initiatively powers on.As shown in the figure, pin Vin and enable signal pin EN are by direct or indirect connecting together, as long as pin Vin has input, the enable signal that enable signal pin EN receives just effectively.The source in case pin Vin Connects Power, the hot plug control circuit will power on to hot plug module, and is not subjected to the constraint and the restriction of other any conditions, and promptly as long as pin Vin touches the power supply on the backboard, business module will unconditionally power on.
Fig. 2 is the schematic diagram of existing business module insertion process medium dip situation.As shown in Figure 2, if insert firmly unevenly, run-off the straight is inserted, and power connector connects earlier have been gone up, and signal is not with on the control connector also is connected fully; According to the characteristic of the mode that initiatively powers on described above, as long as pin Vin has input, module will be powered on.Following problem can appear in this moment:
1, increased the control pin on the connector at the probability that damages under the charged insertion situation: because can not be connected in series electric capacity usually on low speed digital signal circuit on the backboard or the control circuit, when modular belt is electrically interposed in contact, owing to there is not to realize the electric capacity of isolation buffer effect, make the pin of charged module directly link to each other, cause the damage of pin easily;
2, when some configuration pin of business module needs administration module that drive signal is provided, because this moment, these configuration pin did not also contact with backboard fully, but business module powers on, therefore causes the business module configuration error easily.
3, because we can't judge the custom of user's plug-in module, therefore the process of inserting is not easy control, if power connector pin Vin stablizes connection or has shake to take place in the insertion process, may cause the frequent power-on and power-off of module, this in addition may to other the module of operate as normal cause adverse effect.
