Embodiment
For lacking the problem that can effectively control the scheme of switch power-on and power-off in prior art, the embodiment of the present invention provides a kind of management board, this management board can be arranged in switch, as shown in Figure 2, this management board 20 comprises its structure: the first management control unit 21 and the second management control unit 22.Wherein:
Above-mentioned the first management control unit 21, the principal voltage in the Switching Power Supply in switch is powered, for supervising the running status of switch.
Above-mentioned the second management control unit 22, the bypass voltage in the Switching Power Supply in switch is powered, and for controlling the Switching Power Supply 23 of switch, uses principal voltage to carry out power-on and power-off operation to switch.
Management control unit in the switch of prior art only can be supervised the running status of switch, and whether the unit existing in switch such as judgement, and monitor the operating state of these unit for example, has abnormal etc.; Can not use principal voltage to carry out power-on and power-off operation to switch by control switch power supply, because two kinds of voltages of Switching Power Supply support output, a kind of be the principal voltage of 12V, and a kind of is the bypass voltage of 3.3V.Switching Power Supply can be controlled the output of 12V voltage, for example can pass through the signal controlling of the pin PSON# of Switching Power Supply, when the PSON# of Switching Power Supply is high level, 12V normally exports, when the PSON# of Switching Power Supply is low level, 12V is output not, can certainly control by other means, repeats no more here; The output of the bypass of 3.3V (Standby) voltage is not controlled by Switching Power Supply, as long as the input of 220V alternating current exists, 3.3V bypass Voltage-output just exists.The 3.3V bypass Voltage-output electric current of general Switching Power Supply is smaller, thereby does not supply the device of large power consumption.
In the present invention, the first management control unit is the 12V power voltage supply exported by Switching Power Supply, the second management control unit is the 3.3V bypass power voltage supply exported by Switching Power Supply, because 3.3V bypass voltage is not controlled by Switching Power Supply, that is to say that the second management control unit can be in running order all the time, thereby can be carried out by the second management control unit the principal voltage of control switch power supply output 12V, and then control switch power supply is used principal voltage to carry out power-on and power-off operation to switch.When switch is during in power-down state, the second management control unit can carry out to switch the operation that powers on by Switching Power Supply; When switch is during in power-up state, the second management control unit can be carried out lower electricity operation to switch by Switching Power Supply, management board in the present invention can achieve effective control switch power-on and power-off operation, the mode that needs the power-on and power-off operation of Artificial Control switch with respect to prior art, operating efficiency and accuracy rate have all obtained effectively improving.
Certainly the 12V voltage of Switching Power Supply output is except giving the first management control unit power supply in management board; also for other components and parts power supplies such as the line card to switch, fan disk; first the 12V electricity of Switching Power Supply output can pass through the hot-swap controller on these element devices of management board, line card, fan disk etc.; and then to give these components and parts power supplies, the Main Function of the hot-swap controller be not to be damaged during for the plug of baffle cassette tape electricity.
Management board, line card, Switching Power Supply etc. components and parts can be set directly on the cabinet of switch, also two backboards can be set on switch, a power supply backplane, a System Backplane, Switching Power Supply is arranged on power supply backplane, management board, line card etc. are arranged on System Backplane, between power supply backplane and System Backplane, by cable, connect.The mode that can certainly adopt other, repeats no more here.
Introduce the switch architecture in the embodiment of the present invention above, introduced in detail each unit and corresponding operation principle below.
Concrete, as shown in Figure 2, above-mentioned the first management control unit 21 comprises a CPU211 and a CPLD212, the second management control unit 22 comprises the 2nd CPU221 and the 2nd CPLD222; Wherein, the 2nd CPU221, for control the principal voltage output state of the Switching Power Supply 23 of switch by the 2nd CPLD222, realizes switch is carried out to power-on and power-off operation.
The Comparision that the 2nd CPU will do is simple, as long as can meet by the output state of a CPLD control switch power supply, thereby realize, switch is carried out to power-on and power-off operation, therefore, when selecting the 2nd CPU, need to support road iic bus and an asynchronous bus, because CPU may carry out simple agreement, thereby need to support outside can expand SDRAM.If the 2nd CPU selecting just can normally work at 3.3V voltage, the 3.3V bypass voltage that can directly export by Switching Power Supply so, if what need is other voltages, the 3.3V bypass voltage that can export by Switching Power Supply is so through being converted to needed voltage.
The interface signal of existing Switching Power Supply is except PSON#, also have other, (it is that low expression Switching Power Supply exists that this signal can be set to the PSRENT# existing such as indicator cock power supply, for representing Switching Power Supply, height do not exist), (it is low expression fan failure that this signal can be set to the FAN FAIL# of indicator cock power supply fan inside state, for height represents that fan is normal), (it is that low expression Switching Power Supply output is normal that this signal can be set to the whether normal PwrOK# of indicator cock power supply output, for height represents Switching Power Supply output fault) etc., these signals can be connected on the 2nd CPLD.Switching Power Supply can be used one, also can use a plurality of simultaneously, when use is a plurality of, the 2nd CPLD can be each Switching Power Supply difference output signal, then the signal of each Switching Power Supply output is carried out again switch being carried out to power-on and power-off operation after logical operation, using one to be the same with using a plurality of effects reaching, is variant to the control meeting of power supply, take below and uses a Switching Power Supply to describe as example.
Between the 2nd CPU and the 2nd CPLD, communicate to connect, can be interconnected by asynchronous bus, the 2nd CPU obtains Switching Power Supply by the 2nd CPLD and signal the signals such as PSON# of control switch power supply such as whether has.Asynchronous bus can be used Serial Peripheral Interface (the Serial Peripheral Interface of CPU, SPI), local bus (Local bus) or universal input output (General Purpose Input Output, GPIO) etc.
The signal of the upper connecting valve power supply output of the 2nd CPLD, and to Switching Power Supply output PSON# signal, is used for the output state of control switch power supply, thereby realizes the operation of switch being carried out to power-on and power-off.
The communication port of the 2nd CPU and the first management control unit can be selected universal asynchronous transmission and reception apparatus (Universal Asynchronous Receiver Transmitter, UART).
Concrete, when switch starts first, above-mentioned the 2nd CPU can carry out the following step, and concrete steps are as shown in Figure 3.
S30: start.
S31: detect in switch whether have the opposite end management board with the management board at self place with master slave relation, when testing result is not when existing, execution S32; When testing result is when existing, carry out S33.
S32: the principal voltage output state of controlling the Switching Power Supply in switch by the 2nd CPLD is effective status, realizes switch is carried out to the operation that powers on.
S33: the current output state of principal voltage of sense switch power supply, when the output state of principal voltage being detected and be effective status, carry out S34; When principal voltage output state being detected and be disarmed state, carry out S35.
S34: the output state of the principal voltage of maintained switch power supply is effective status.
S35: the reason that the current output state of the principal voltage of judgement Switching Power Supply is disarmed state, if former because switch starts first, carry out S36; If reason for people be power-off, carry out S37.
S36: the output state of controlling the principal voltage of the Switching Power Supply in switch by the 2nd CPLD is effective status, realizes switch is carried out to the operation that powers on.
S37: the output state of the principal voltage of maintained switch power supply is disarmed state.
Generally, in switch, two management boards can be set, two management boards can be after consulting one as main management plate, a conduct is from management board, when main management plate breaks down, from management board, can take over the work of main management plate, switch can also run well.Therefore,, when switch starts to start, management board need to detect whether there is another management board, then operates accordingly.Introduce when switch starts following three kinds of situations that may exist below:
The first situation: only have a management board.
When switch starts, in the situation that the 220V of Switching Power Supply input exists, 3.3V voltage is normally exported, the second management control unit can normally start, whether the 2nd CPU detects opposite end management board by the 2nd CPLD and exists, because only have the management board at the second management control unit self place, so opposite end management board does not exist, the 2nd CPU can be directly just effective status by the 2nd CPLD control switch power supply output state so, namely 12V voltage is normally exported, thereby the first management control unit on management board can normally start.After the normal startup of the first management control unit, the management board at the first management control unit place, is exactly as main management plate naturally.
The second situation: only have a management board when switch starts, insert again second management board after switch starts.
The management board existing when switch starts is identical for the control of Switching Power Supply with the first situation, whether the 2nd CPU in the management board of rear insertion also can go to detect opposite end management board and exist, owing to there being the management board of first insertion, Switching Power Supply likely by people for having closed, also likely normally output.Therefore, need to obtain the output state of Switching Power Supply this time, can obtain by reading PwOK# signal in the present embodiment.
If PwOK# signal is low, the second management control unit that opposite end management board is described the output state of control switch power supply is effective status, realization is carried out to power on to switch and has been operated, and opposite end management board is the status in main management plate, this time is due to 12V power supply normal presence, CPU on rear insertion management board just can directly start, and can master-slave negotiation be from management board.
If PwOK# signal is high, the output state that Switching Power Supply is described is disarmed state, and 12V voltage is output not, illustrate Switching Power Supply by user people for closing, this time can not control switch power supply output state be effective status, also just can not realize switch to carry out to power on having operated.
The third situation: have two management boards when switch starts.
Now, on two management boards, the 2nd CPU of the second management control unit can normally start, and opposite end management board existence can be detected, and then obtains the output state of Switching Power Supply.
If the output state of the Switching Power Supply getting is effective status, two management boards can normally start, and then can carry out master-slave negotiation, and one is from management board for main management plate to negotiate one, and switch just can start normal work.
If the output state of the Switching Power Supply getting is disarmed state, the also not output of 12V voltage of Switching Power Supply is described, from the second situation, we know that the output state of Switching Power Supply is that disarmed state is likely that people closes, likely that switch starts first, if artificially have a mind to close, so, just can not carry out the operation that powers on, but if switch starts first, just can carry out to power on and operate, therefore, at this moment just need the reason that the output state of sense switch power supply is disarmed state.If former because switch starts first, the Switching Power Supply output state of controlling in switch by the 2nd CPLD is effective status, realizes switch is carried out to the operation that powers on; If reason for people be power-off, the output state of maintained switch power supply is disarmed state.
Preferably, when switch is normally worked, an above-mentioned CPU sends heartbeat signal by a CPLD to the 2nd CPLD; When the 2nd CPU does not get the heartbeat signal of a CPU transmission by the 2nd CPLD in setting-up time length, detect in switch and whether have the opposite end management board with the management board at self place with master slave relation, if testing result is not when existing, the output state that passes through the principal voltage of the Switching Power Supply in the 2nd CPLD control switch is first that disarmed state is effective status again, realizes carrying out the operation that powers on after electric operation under switch execution again.
A kind of preferably execution mode, the heartbeat signal that can make a CPU on management board and the 2nd CPU simultaneously monitor the other side, can transmit HBIN by a CPLD and the 2nd CPLD, HBOUT signal transmits mutually heartbeat signal, can certainly be other heartbeat signal.When the 2nd CPU finds that a CPU does not have heartbeat signal, that is to say the first management control unit cisco unity malfunction, whether the 2nd CPU just can go to detect opposite end management board and exist so, if opposite end management board does not exist, can be first that disarmed state is effective status again by passing through the 2nd CPLD control switch power supply output state, can realize and switch is first carried out to lower electricity operation re-power again operation, make management board recover normal work.If opposite end management board has existence, opposite end management board simultaneously also can monitor this management board cisco unity malfunction, thereby opposite end management board can guarantee the normal work of whole system, thereby can carry out power-on and power-off and recover.
Concrete, above-mentioned the 2nd CPU, is the reason flag bit of invalid reason for detection of the current output state of identification switch power supply, reason flag bit being detected, is 0 o'clock, determines former because switch starts first.
Reason can be set in the 2nd CPLD and indicate a reason that the output state that carrys out identification switch power supply is disarmed state, it is to represent that switch is for starting first at 0 o'clock that reason flag bit can be set, and is to represent artificial closing switch power supply at 1 o'clock.Between the 2nd CPLD in the second management control unit of two management boards, can exchange reason flag bit by UART.
In above-mentioned the third situation in two simultaneous situations of management board, the 2nd CPU of the second management control unit in two management boards can detect the other side's reason flag bit, when being is all 0, two the 2nd CPU can be by self place the output state of the 2nd CPLD control switch power supply of management board be effective status, at this moment the output state of Switching Power Supply is effective status, 12V voltage is normally exported, the first management control unit on two management boards starts to start, and then carries out master-slave negotiation.
Preferably, under switch normal operating conditions, can also receive lower electricity request.When receiving lower electricity request, an above-mentioned CPU sends lower electricity request by a CPLD and the 2nd CPLD to the 2nd CPU; The lower electricity request that the 2nd CPU sends according to a CPU who receives by the 2nd CPLD, detect in switch and whether have the opposite end management board with the management board at self place with master slave relation, when testing result is not when existing, the output state of controlling the principal voltage of the Switching Power Supply in switch by the 2nd CPLD is disarmed state, realizes switch is carried out to lower electricity operation; When testing result is when existing, the lower electricity request receiving is transmitted to opposite end management board, and is disarmed state by the output state that the 2nd CPLD controls the principal voltage of the Switching Power Supply in switch, realize switch is carried out to lower electricity operation.
Between the one CPU and the 2nd CPU, a communication port can be set, like this, user can apply for by the control desk of management board the output state of control switch power supply, thereby realize, switch is carried out to lower electricity operation.
Concrete, on above-mentioned the 2nd CPLD, be connected with for detection of the detection contact that whether has opposite end management board in switch; The 2nd CPU, for detecting by the 2nd CPLD when detecting contact and being low level, confirms to have opposite end management board in switch, and detecting when detecting contact and being high level, confirms not have opposite end management board in switch.
Whether the circuit in employing Fig. 4 can detect opposite end management board and exist, and shown in figure is the situation that has management board A and two management boards of management board B.For management board A, when opposite end management board B exists, detection contact A is low level, and namely the Present# signal in Fig. 2 is low level; When opposite end management board B does not exist, detection contact A is high level, and namely the Present# signal in Fig. 2 is high level.For management board B, the situation that detects a B is also identical.Here be only to have enumerated to detect a kind of mode whether opposite end management board exists, can certainly adopt other mode to detect opposite end management board and whether exist, repeat no more here.
Concrete, above-mentioned the 2nd CPU is provided with network communication interface; The 2nd CPU receives by network communication interface after user's power-on and power-off request, controls the output state of the Switching Power Supply in switch by the 2nd CPLD, realizes switch is carried out to power-on and power-off operation.
A network communication interface can be set on the second management control unit, by this network communication interface, can realize the long-range management to switch, and under corresponding software support, switch can be accessed to unified management platform, realize the unified management to many switches.
Network communication interface can be 100,000,000 electricity mouthful or other interfaces, and 100,000,000 electricity mouthful of take below describe as example.When user sends after lower electricity request by 100,000,000 electricity mouths, the 2nd CPU is 1 by the reason mark position in the 2nd CPLD, and the output state of control switch power supply is disarmed state.Whether detect opposite end management board exists simultaneously, if opposite end management board exists, lower electricity request is delivered on the second management control unit of opposite end management board by UART passage, the 2nd CPU of opposite end management board receives after this request, also the output state of control switch power supply is disarmed state, when the second management of two management boards, control singly when all the output state of control switch power supply is disarmed state, Switching Power Supply is no longer exported 12V voltage, has realized switch is carried out to lower electricity operation.
When receiving that from 100,000,000 electricity mouths while powering on request, the 2nd CPU is 0 by the reason mark position in the 2nd CPLD, and the output state of control switch power supply is effective status, and Switching Power Supply output 12V voltage, realizes switch is carried out to the operation that powers on; Whether detect opposite end management board exists simultaneously, if opposite end management board exists, the request of powering on is delivered on the second management control unit of opposite end management board by UART passage, the 2nd CPU of opposite end management board receives after the request of powering on, also the output state of control switch power supply is effective status, now because Switching Power Supply has been exported 12V voltage, so need not carry out the operation that powers on to switch.
Concrete, above-mentioned the second management control unit, also for monitoring the line card of switch and the operating characteristic parameter of Switching Power Supply.
The operating characteristic parameter of line card and Switching Power Supply lamp comprises temperature, power consumption etc. parameter, and these are all to characterize the parameter whether switch normally works, and therefore monitor the performance that these parameters contribute to monitor switch.
In the switch of the prior art shown in Fig. 1, by management board, carry out monitoring temperature, but management board needs to process a lot of work simultaneously, for example: the renewal of routing table, processing of protocol massages etc., therefore the probability ging wrong on management board is also very high, once management board breaks down, for example, when the CPU of management board is absorbed in endless loop, also monitoring temperature more just.In order to address this problem, can carry out the parameters such as monitoring problem by the second management control unit on management board.
EEPROM is mainly used to store the relevant information of the board at place, such as the power consumption of board, the series number etc. of dispatching from the factory of the type of line card, line card.On board, be provided with monitoring temperature chip, for monitoring the temperature of each point on board, for the system of more complicated, can use a plurality of monitoring temperature chips, place respectively different onboard places, such as place the hottest on the air inlet in air channel, air outlet, plate etc.The iic bus of the 2nd CPU output of management board expands the EEPROM that is connected to each board after multichannel iic bus, monitoring temperature chip etc. after I2C bus switch, can obtain the temperature information of system etc.
Because the second management control unit is positioned on management board, and in switch, can be provided with two management boards, thereby also just there are two the second management control units, and line card generally can only be read the iic bus signal on main management plate, so just need management board that principal and subordinate's information is delivered to the second management control unit, can be by the Master# signal in shown in Fig. 2.When the 2nd CPLD monitors Master# signal condition and changes, can notify the 2nd CPU.Suppose, in switch, be provided with these two management boards of management board A and management board B, the circuit theory of any one line card in switch as shown in Figure 5 so, wherein MasterA and MasterB are respectively the master slave mode index signal from management board A and management board B, MUX connects from management board A and management board B two-way iic bus, MasterA and MasterB are used for controlling the switch of MUX, thereby select two-way iic bus Zhong mono-tunnel from two management boards.For example, when management board A is main management plate, MasterA is main signal, and MUX will be selected the iic bus from management board A so; When management board B is main management plate, MUX will be selected the iic bus from management board B.
The mode of the running parameters such as temperature, power consumption is obtained in lower mask body introduction, and 100,000,000 electricity mouthful Remote Acquisitionings that can the second management control unit, also can obtain by the control desk of management board.
When user is sent and obtained after the request of temperature, power etc. by 100,000,000 electricity mouthful, the 2nd CPU reads the Master# signal in the 2nd CPLD, if self be positioned on main management plate, so directly by iic bus, obtained the information such as corresponding temperature, power consumption, and feed back to user.If self be positioned at from management board, by UART passage, the request of obtaining temperature, power etc. is delivered to the 2nd CPU on main management plate so, the 2nd CPU on main management plate obtains the information such as temperature, power consumption after receiving request by iic bus, then by UART passage, pass to the 2nd CPU from management board again, the 2nd CPU from management board crosses information exchange 100,000,000 electric oral instructions again and passs user.
When user initiates to obtain after the request of temperature, power by the control desk of management board, a CPU on management board by request by and the 2nd CPU between UART passage request is delivered to the 2nd CPU, the 2nd CPU can be according to obtaining the information such as temperature, power with similar mode from 100,000,000 electricity mouths receive request, and by UART passage, being delivered to a CPU of management board, a CPU of management board crosses control desk by these information exchanges again and exports to user.
The second management control unit can adopt interrupt mode to monitor information such as the temperature of switch, power consumptions, monitoring temperature chip end signal in the reach preset temperature value time output of the temperature of monitoring namely, as long as notify the 2nd CPLD end signal in these, the 2nd CPLD just can monitor these interrupt signals, then notify the 2nd CPU, can report by INT# pin, can certainly report by other means.The 2nd CPLD is the various states of pilot switch power supply simultaneously also, when changing, also can report to the 2nd CPU by INT# pin.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
