Embodiment
To lacking the problem that effectively to control the scheme of switch power-on and power-off in the prior art; The embodiment of the invention provides a kind of management board; This management board can be arranged in the switch; Its structure is as shown in Figure 2, and this management board 20 comprises: first management control unit 21 and second management control unit 22.Wherein:
Above-mentioned first management control unit 21 is supplied power by the principal voltage in the Switching Power Supply in the switch, is used to supervise the running status of switch.
Above-mentioned second management control unit 22 is supplied power by the bypass voltage in the Switching Power Supply in the switch, and the Switching Power Supply 23 use principal voltages that are used for controlling switch are to switch execution power-on and power-off operation.
Whether the management control unit in the switch of prior art only can be supervised the running status of switch, such as judging the unit that exists in the switch, and monitors the operating state of these unit, for example, have unusual or the like; Can not control switching use principal voltage that switch is carried out the power-on and power-off operation, 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 was high level, 12V normally exported; When the PSON# of Switching Power Supply is low level; 12V is output not, can certainly control through other modes, repeats no more here; 3.3V the output of bypass (Standby) voltage be not receive Switching Power Supply control, as long as the input of 220V alternating current exists, the output of 3.3V bypass voltage just exists.The 3.3V bypass voltage output current of general Switching Power Supply is smaller, thereby has supplied not the device of big power consumption.
In the present invention; First management control unit is by the 12V power voltage supply of Switching Power Supply output; Second management control unit is by the 3.3V bypass power voltage supply of Switching Power Supply output; Because 3.3V bypass voltage is not receive Switching Power Supply control; That is to say that second management control unit can be in running order all the time, thereby can come the principal voltage of control switching output 12V, and then control switching uses principal voltage that switch is carried out the power-on and power-off operation by second management control unit.When switch was in power-down state, second management control unit can be carried out the operation that powers on to switch through Switching Power Supply; When switch is in power-up state; Second management control unit can be carried out electricity operation down to switch through Switching Power Supply; Management board among the present invention can the achieve effective control switch the power-on and power-off operation; With respect to the mode that prior art needs the power-on and power-off of Artificial Control switch to operate, operating efficiency and accuracy rate have all obtained improving effectively.
Certainly first management control unit power supply of the 12V voltage of Switching Power Supply output in giving management board; Also be used for other components and parts power supplies such as ply-yarn drill, fan disk to switch; The 12V electricity of Switching Power Supply output at first can pass through the hot-swappable controller on these element devices of management board, ply-yarn drill, fan disk or the like; And then supply power for these components and parts, the main effect of hot-swappable controller is not to be damaged when being used for the plug of baffle cassette tape electricity.
Management board, ply-yarn drill, Switching Power Supply or the like 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 is arranged on Switching Power Supply on the power supply backplane; Management board, ply-yarn drill or the like are arranged on the System Backplane, connect through cable between power supply backplane and the System Backplane.Can certainly adopt other mode, repeat no more here.
Introduce the switch architecture in the embodiment of the invention above, introduced each unit and corresponding work principle below in detail.
Concrete, as shown in Figure 2, above-mentioned first management control unit 21 comprises a CPU211 and a CPLD212, second management control unit 22 comprises the 2nd CPU221 and the 2nd CPLD222; Wherein, the 2nd CPU221 is used for the principal voltage output state through the Switching Power Supply 23 of the 2nd CPLD222 control switch, realizes switch is carried out the power-on and power-off operation.
The work that the 2nd CPU will do is fairly simple; As long as can satisfy output state, thereby realize that switch is carried out the power-on and power-off operation to get final product, therefore through a CPLD control switching; When selecting the 2nd CPU; Need to support one road iic bus and asynchronous bus,, thereby need to support the outside can expand SDRAM because CPU may carry out simple agreement.If the 2nd CPU that selects just can operate as normal at 3.3V voltage; The 3.3V bypass voltage that can directly export so with Switching Power Supply; If desired be other voltages, 3.3V bypass voltage that so can be through Switching Power Supply output is through being converted to needed voltage.
The interface signal of existing Switching Power Supply is except PSON#; Also have other; (this signal can be set to be existed for low expression Switching Power Supply the PSRENT# that exists such as the indicator cock power supply; Representing Switching Power Supply for height does not exist), the FAN FAIL# of indicator cock power supply fan inside state (can be provided with this signal and be low expression fan failure; For height representes that fan is normal), indicator cock power supply output normal PwrOK# (it is normal for the output of low expression Switching Power Supply that this signal can be set, for height is represented Switching Power Supply output fault) etc. whether, these signals can be connected on the 2nd CPLD.Switching Power Supply can be used one; Also can use simultaneously a plurality of, use a plurality of in, the 2nd CPLD can export signal respectively for each Switching Power Supply; Signal to each Switching Power Supply output carries out again switch being carried out the power-on and power-off operation after the logical operation then; Use one to be the same with using a plurality of effects that reaches, just variant to the control meeting of power supply, below to use a Switching Power Supply to describe as example.
Communicating by letter between the 2nd CPU and the 2nd CPLD is connected, can be interconnected through asynchronous bus, and the 2nd CPU obtains Switching Power Supply through the 2nd CPLD and the signal and the signals such as PSON# of control switching such as whether has.Asynchronous bus can use CPU Serial Peripheral Interface (Serial Peripheral Interface, SPI), local bus (Local bus) or general input and output (General Purpose Input Output, GPIO) etc.
The 2nd CPLD go up to connect the signal of Switching Power Supply output, and to Switching Power Supply output PSON# signal, is used for the output state of control switching, thereby realizes switch is carried out the operation of power-on and power-off.
The communication port of the 2nd CPU and first management control unit can select for use universal asynchronous transmission and reception apparatus (Universal Asynchronous Receiver Transmitter, UART).
Concrete, when switch started first, above-mentioned the 2nd CPU can carry out the following step, and concrete steps are as shown in Figure 3.
S30: beginning.
S31: detect the opposite end management board that whether exists the management board with self place to have master slave relation in the switch, when testing result when not existing, execution S32; When testing result when existing, carry out S33.
S32: the principal voltage output state through the Switching Power Supply in the 2nd CPLD control switch is an effective status, realizes switch is carried out the operation that powers on.
S33: the output state that the principal voltage of sense switch power supply is current, when the output state that detects principal voltage is effective status, carry out S34; When detecting the principal voltage output state and be disarmed state, carry out S35.
S34: the output state of the principal voltage of maintained switch power supply is an effective status.
S35: the current output state of judging the principal voltage of Switching Power Supply is the reason of disarmed state, if former because switch starts first, carries out S36; If reason is artificial outage, carry out S37.
S36: the output state of controlling the principal voltage of the Switching Power Supply in the switch through the 2nd CPLD is an effective status, realizes switch is carried out the operation that powers on.
S37: the output state of the principal voltage of maintained switch power supply is a disarmed state.
Generally in switch, two management boards can be set, two management boards can through negotiation back one as the main management plate; A conduct is from management board; When the main management plate breaks down, can take over the work of main management plate from management board, switch can also run well.Therefore, when switch began to start, management board need detect whether there is another management board, operates accordingly then.When being presented in the switch startup below, following three kinds of situation that possibly exist:
First kind of situation: only have a management board.
When switch starts; Under the situation that the 220V of Switching Power Supply input exists, 3.3V voltage is normally exported, and second management control unit can normally start; Whether the 2nd CPU detects the opposite end management board through the 2nd CPLD and exists; Because have only the management board at second management control unit self place, so the opposite end management board does not exist, the 2nd CPU can be an effective status through the 2nd CPLD control switching output state directly just so; Just 12V voltage is normally exported, thereby first management control unit on the management board can normally start.After the normal startup of first management control unit, the management board at first management control unit place is exactly as the main management plate naturally.
Second kind of situation: when switch starts, have only a management board, after switch starts, insert second management board again.
The management board that exists when switch starts is identical for the control of Switching Power Supply with first kind of situation; Whether the 2nd CPU in the management board that insert the back also can go to detect the opposite end management board and exist; Because the management board of insertion has earlier been arranged; Switching Power Supply might also might normally be exported by the people for having closed.Therefore, need obtain the output state of Switching Power Supply this time, can obtain through reading the PwOK# signal in the present embodiment.
If the PwOK# signal is low; Second management control unit that the opposite end management board is described the output state of control switching is an effective status; Realization is carried out to power on to switch and has been operated, and the opposite end management board has been in the status of main management plate, and this time is because 12V power supply normal presence; The CPU that insert on the management board back just can directly start, and can master-slave negotiation be from management board.
If the PwOK# signal is high; The output state that Switching Power Supply is described is a disarmed state, and 12V voltage is output not, explain Switching Power Supply by user people for closing; This time can not control switching output state be effective status, also just can not realize switch carried out to power on having operated.
The third situation: when switch starts, have two management boards.
At this moment, the 2nd CPU of second management control unit can normally start on two management boards, and can detect the opposite end management board and exist, and then obtains the output state of Switching Power Supply.
If the output state of the Switching Power Supply that gets access to is an effective status, two management boards can normally start, and can carry out master-slave negotiation then, negotiate one and are the main management plate, and one is from management board, and switch just can begin operate as normal.
If the output state of the Switching Power Supply that gets access to is a disarmed state, the also not output of 12V voltage of Switching Power Supply is described, we know that the output state of Switching Power Supply is that disarmed state might be that the people closes from second kind of situation; Might be 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, be the reason of disarmed state with regard to the output state that needs the sense switch power supply at this moment.If former because switch starts first, be effective status through the Switching Power Supply output state in the 2nd CPLD control switch, realize switch is carried out the operation that powers on; If reason is artificial outage, the output state of maintained switch power supply is a disarmed state.
More excellent, when the switch operate as normal, an above-mentioned CPU sends heartbeat signal through a CPLD to the 2nd CPLD; When the 2nd CPU does not get access to the heartbeat signal that a CPU sends through the 2nd CPLD in setting-up time length; Detect and whether have the opposite end management board that has master slave relation with the management board that self belongs in the switch; If testing result is not when existing; The output state that then passes through the principal voltage of the Switching Power Supply in the 2nd CPLD control switch is earlier that disarmed state is effective status again, realizes the switch execution is carried out the operation that powers on after the electricity operation down again.
A kind of more excellent execution mode; The heartbeat signal that can make a CPU and the 2nd CPU on the management board monitor the other side simultaneously; Can transmit HBIN through a CPLD and the 2nd CPLD, the HBOUT signal transmits heartbeat signal mutually, 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 the opposite end management board and exist so, if the opposite end management board does not exist, and can be through be earlier that disarmed state is effective status again through the 2nd CPLD control switching output state; The electricity operation re-powers operation more promptly can to realize carrying out down earlier to switch, makes management board recover operate as normal.If the opposite end management board has existence, the opposite end management board simultaneously also can monitor this management board cisco unity malfunction, thereby the opposite end management board can guarantee the operate as normal of whole system, thereby can carry out power-on and power-off and recover.
Concrete, above-mentioned the 2nd CPU is used to detect the current output state of sign Switching Power Supply and is the reason flag bit of invalid reason, is 0 o'clock detecting the reason flag bit, confirms former because switch starts first.
Reason can be set in the 2nd CPLD, and to indicate the output state that the position identifies Switching Power Supply be the reason of disarmed state, the reason flag bit can be set be at 0 o'clock and represent switch for starting first, is to represent artificial off switch power supply at 1 o'clock.Can exchange the reason flag bit through UART between the 2nd CPLD in second management control unit of two management boards.
In above-mentioned the third situation under two simultaneous situation of management board; The 2nd CPU of second management control unit in two management boards can detect the other side's reason flag bit; When all being is 0; Two the 2nd CPU can be through self place the output state of the 2nd CPLD control switching of management board be effective status, at this moment the output state of Switching Power Supply is an effective status, 12V voltage is normally exported; First management control unit on two management boards begins to start, and carries out master-slave negotiation then.
More excellent, under the switch normal operating conditions, can also receive down the electricity request.When receiving down the electricity request, an above-mentioned CPU sends electricity request down through a CPLD and the 2nd CPLD to the 2nd CPU; The following electricity request that the 2nd CPU sends according to a CPU who receives through the 2nd CPLD; Detect and whether have the opposite end management board that has master slave relation with the management board that self belongs in the switch; When testing result when not existing; The output state of controlling the principal voltage of the Switching Power Supply in the switch through the 2nd CPLD is a disarmed state, realizes switch is carried out electric down the operation; When testing result when existing, the following electricity request that receives is transmitted to the opposite end management board, and the output state of the principal voltage through the Switching Power Supply in the 2nd CPLD control switch is disarmed state, realize switch is carried out electricity operation down.
Between the one CPU and the 2nd CPU communication port can be set, like this, the user can apply for the output state of control switching through the control desk of management board, thereby realizes switch is carried out electricity operation down.
Concrete, be connected with on above-mentioned the 2nd CPLD and be used for detecting the detection contact whether switch exists the opposite end management board; The 2nd CPU is used for confirming to have the opposite end management board in the switch detecting through the 2nd CPLD when detecting the contact and being low level, and detecting when detecting the contact and being high level, confirms not have the opposite end management board in the switch.
Whether the circuit among employing Fig. 4 can detect the opposite end management board and exist, and shown in the 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 existed, the detection contact A was a low level, and just the Present# signal in Fig. 2 is a low level; When opposite end management board B did not exist, the detection contact A was a high level, and just the Present# signal among Fig. 2 is a high level.For management board B, the situation that detects a B also is identical.Here only be to have enumerated to detect a kind of mode whether the opposite end management board exists, can certainly adopt other mode to detect the opposite end management board and whether exist, repeat no more here.
Concrete, above-mentioned the 2nd CPU is provided with network communication interface; After the 2nd CPU receives user's power-on and power-off request through network communication interface,, realize switch is carried out the power-on and power-off operation through the output state of the Switching Power Supply in the 2nd CPLD control switch.
A network communication interface can be set on second management control unit; Can realize long-range management through this network communication interface to switch; And under the corresponding software support, can switch be inserted unified management platform, realize unified management many switches.
Network communication interface can be 100,000,000 electricity mouth or other interfaces, is that example describes with 100,000,000 electricity mouths below.After the user sent down the electricity request through 100,000,000 electricity mouths, the 2nd CPU was 1 with the reason mark position among the 2nd CPLD, and the output state of control switching is a disarmed state.Whether detect the opposite end management board simultaneously exists; If the opposite end management board exists, following electricity request is delivered on second management control unit of opposite end management board through the UART passage, after the 2nd CPU of opposite end management board receives this request; Also the output state of control switching is a disarmed state; When the second management control of two management boards is single when all the output state of control switching is disarmed state, Switching Power Supply is no longer exported 12V voltage, has realized switch is carried out electricity operation down.
When receiving that from 100,000,000 electricity mouths when powering on request, the 2nd CPU is 0 with the reason mark position among the 2nd CPLD, and the output state of control switching is effective status, and Switching Power Supply output 12V voltage is realized switch is carried out the operation that powers on; Whether detect the opposite end management board simultaneously exists; If the opposite end management board exists; The request of powering on is delivered on second management control unit of opposite end management board through the UART passage, and after the 2nd CPU of opposite end management board received the request of powering on, also the output state of control switching was an effective status; This moment is because Switching Power Supply has been exported 12V voltage, so need not carry out the operation that powers on to switch.
Concrete, above-mentioned second management control unit also is used for monitoring the ply-yarn drill of switch and the operating characteristic parameter of Switching Power Supply.
The operating characteristic parameter of ply-yarn drill and Switching Power Supply lamp comprises temperature, power consumption or the like parameter, and these all are to characterize the whether parameter of operate as normal of switch, therefore monitor the performance that these parameters help to monitor switch.
In the switch of prior art shown in Figure 1; Come monitoring temperature through management board, but management board need be handled a lot of work simultaneously, for example: the renewal of routing table, processing of protocol massages or the like; Therefore the probability that goes wrong on the management board is also very high; In case management board breaks down, when for example the CPU of management board is absorbed in endless loop, also monitoring temperature more just.In order to address this problem, can come parameters such as monitoring problem through second management control unit on the management board.
EEPROM mainly is used for storing the relevant information of the integrated circuit board at place, the for example series number etc. of dispatching from the factory of the type of the power consumption of integrated circuit board, ply-yarn drill, ply-yarn drill.Integrated circuit board is provided with the monitoring temperature chip; Be used to monitor the temperature of each point on the integrated circuit board,, can use a plurality of monitoring temperature chips for the system of more complicated; Place different onboard places respectively, such as place the hottest on the air inlet in air channel, air outlet, the plate etc.The iic bus of the 2nd CPU of management board output expands the EEPROM that is connected to each integrated circuit board behind the multichannel iic bus, monitoring temperature chip etc. after through the I2C bus switch, can obtain the temperature information of system etc.
Because second management control unit is positioned on the management board; And can be provided with two management boards in the switch; Thereby two second management control units are just arranged also; And ply-yarn drill generally can only be read the iic bus signal on the main management plate, so just needs management board that principal and subordinate's information is delivered to second management control unit, can be through the Master# signal in shown in Fig. 2.The 2nd CPLD monitors the Master# signal condition when changing, and can notify the 2nd CPU.Suppose; Be provided with these two management boards of management board A and management board B in the switch; The circuit theory of any ply-yarn drill in the switch is as shown in Figure 5 so, and wherein MasterA and MasterB are respectively the master slave mode index signal from management board A and management board B, and 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 from a road in the two-way iic bus of two management boards.For example, when management board A was the main management plate, MasterA was a main signal, and MUX will be selected the iic bus from management board A so; When management board B was the main management plate, MUX will be selected the iic bus from management board B.
The mode of running parameters such as temperature, power consumption is obtained in following mask body introduction, and 100,000,000 electricity mouthful long-range obtaining that can second management control unit also can be obtained through the control desk of management board.
After the user obtains the request of temperature, power etc. through mouthful transmission of 100,000,000 electricity; The 2nd CPU reads the Master# signal among the 2nd CPLD; If self be positioned on the main management plate, so directly obtain information such as corresponding temperature, power consumption, and feed back to the user through iic bus.If self be positioned at from management board; The request that to obtain temperature, power etc. through the UART passage so is delivered to the 2nd CPU on the main management plate; The 2nd CPU on the main management plate receives that the request back obtains information such as temperature, power consumption through iic bus; Then pass to the 2nd CPU from the management board through the UART passage again, the 2nd CPU from management board passs the user with information through 100,000,000 electric oral instructions again.
After the user initiates to obtain the request of temperature, power through the control desk of management board; CPU on the management board will ask through and the 2nd CPU between the UART passage request is delivered to the 2nd CPU; The 2nd CPU can be according to obtaining information such as temperature, power with similar mode after the 100000000 electricity mouth requests of receiving; And being delivered to a CPU of management board through the UART passage, a CPU of management board exports to the user with these information through control desk again.
Second management control unit can adopt interrupt mode that information such as the temperature of switch, power consumption are monitored; End signal during just the monitoring temperature chip is exported when the temperature of monitoring reaches preset temperature value; As long as these middle-end signalisations the 2nd CPLD, the 2nd CPLD just can monitor these interrupt signals, notifies the 2nd CPU then; Can certainly report through other modes through the report of INT# pin.The 2nd CPLD is the various states of pilot switch power supply simultaneously also, when changing, also can report to the 2nd CPU through the INT# pin.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
