As shown in figure 1, the present invention proposes a kind of access switch 10, including：
Data exchange unit 100, collecting unit 200 and control unit 300.
Data exchange unit 100 is used to realize the data exchanging function of interchanger.
Collecting unit 200 is used to gather temperature, supply voltage, the working condition of cpu chip and the friendship of access switch 10
Change the packet loss information of chip.
Control unit 300 is used for rotation speed of the fan, the electricity of the information control access switch 10 gathered according to collecting unit 200
Source exports and chip reset.
Various factors of the collecting unit 200 mainly on various influence stability on access switch 10 is monitored, and wraps
Following factor is included：Temperature, internal each road supply voltage, CPU state, business forwarding state, heat abstractor etc..
The collection of every kind of information is all carried out with the default sampling period.For example：Temperature can be with every five seconds for example collection once, CPU cores
Once, the packet loss collection in every 30 seconds of exchange chip is once for the working condition collection in every 1 second of piece.
As shown in Fig. 2 collecting unit 200 specifically include state of temperature, power supply status, fan-status, cpu chip state and
Exchange chip state.Whether the cpu chip state judges CPU normal including the presupposed information that timing acquiring CPU sends
Operation, exchange chip state includes the packet loss of exchange chip.
Temperature has the temperature of following correlation monitoring point：Exchange chip internal temperature, cpu chip internal temperature, interchanger machine
Case air intake vent temperature, switch chassis air outlet temperature, switch chassis inside center temperature.
Switch chassis temperature everywhere is completed by being distributed in the temperature sensor of interchanger surrounding, by data/address bus
The mode of communication, monitoring unit is delivered to by the detecting result of temperature sensor.The internal temperature of chip is related by reading chip
Pin obtain.
Fin is all posted on exchange chip and cpu chip, is beneficial to chip cooling.
The mode that collecting unit is connected by AD conversion with power supply is carried out, and power supply delivers to collecting unit as analog signal,
Digitlization conversion is carried out in collecting unit, collecting unit reads corresponding magnitude of voltage.The precision of AD conversion is converted up to 12
Time below one millisecond.Because chip is very short in the time that can persistently bear high pressure, for protection chip it is without damage, it is necessary to
Accelerate the acquisition time to power supply.
The collection of fan-status is realized by reading the rotating speed of fan, and fan uses four pin lead PWM (Pulse
Width Modulation, pulse width modulation) fan, DC fan in the case where direct current power source voltage is constant, by change
Direct current voltage pulse width (i.e. dutycycle) is adjusting the mode of speed regulation of input voltage average value.The fan have power supply, PWM,
4 pins of rotating speed, collecting unit carries out corresponding computing by reading the waveform of rotating speed can be obtained turning when one of forefan
Speed value.
The collection of CPU state is that have respective bus to connect between collecting unit and CPU, is sent by timing acquiring CPU
Presupposed information judge whether CPU is normally running.If specifically, 20 seconds do not collect, it is assumed that now CPU is different
Often.
The collection of business forwarding state is that CPU is counted by packet loss and wrong bag that bus reads exchange chip, by for a long time
Whether analysis is normal to judge business forwarding state, and informs collecting unit by bus.If specifically, collecting exchange core
The packet loss of piece higher than 20% for up to more than 2 minutes, it is assumed that now exchange chip exception.
Control unit 300 is the sequence of operations carried out after judging the collection information of collecting unit 200, it is ensured that be
The safety that the normal operation of system or next time start.
As shown in figure 3, the concrete operations of control unit 300 are including rotation speed of the fan, power supply output, chip reset etc..Power supply is defeated
Go out including power reset and power switch.
The operation that fan regulation is carried out after being acquired mainly for temperature information.Temperature includes housing temperature and chip temperature
Degree.Housing temperature takes the average value of multiple collection point temperature, and chip temperature takes the maximum of cpu chip temperature and exchange chip temperature
Value.The control instruction of rotation speed of the fan regulation is PWM duty cycle.Tabled look-up according to gained housing temperature and chip temperature and obtain fan turn
The control instruction of velocity modulation section, specific embodiment is as shown in table 1.
The rotation speed of the fan of table 1 is adjusted and temperature relation
| Sequence number | Housing temperature value | Chip temperature value | PWM duty cycle |
| 1 | More than 70 DEG C | More than 90 DEG C | 100 |
| 2 | 66~70 DEG C | 80~89 DEG C | 90 |
| 3 | 61~65 DEG C | 71~79 DEG C | 80 |
| 4 | 56~60 DEG C | 66~70 DEG C | 70 |
| 5 | 51~55 DEG C | 61~65 DEG C | 60 |
| 6 | 46~50 DEG C | 56~60 DEG C | 50 |
| 7 | 40~45 DEG C | 51~55 DEG C | 40 |
| 8 | 36~39 DEG C | 46~50 DEG C | 30 |
| 9 | 30~35 DEG C | 40~45 DEG C | 20 |
| 10 | Less than 30 DEG C | Less than 40 DEG C | 10 |
Table look-up and obtain a corresponding dutycycle according to housing temperature, another corresponding duty is obtained further according to chip temperature
Than taking dutycycle of the dutycycle maximum between the two as access switch fan work.
During adjustment rotation speed of the fan, in addition it is also necessary to the rotating speed Real-time Collection of fan, rotating speed is detected for illegal value, show fan
It has been damaged that, after thering is a fan to occur damaging, in said fans rotational speed regulation list item PWM duties corresponding with temperature relation
Increase by 20% than on the basis of.After there are two and the damage of above fan, PWM full speed runnings.
Collecting unit be to the monitor in real time of voltage to ensure the normal of system power supply, when voltage within the specific limits when be
System will not be processed.When voltage is less than normal range (NR), system carries out reset operation to power supply, resets and still can not reach after three times
To normal value, will carry out closing the operation of power supply.After power supply occurs higher than normal range (NR), horse back is carried out closing behaviour by system
Make, it is ensured that system is not damaged by high pressure.Monitoring in real time is also carried out in power up in addition, when occurring voltage in power up
Shutoff operation is also carried out higher than normal range (NR).
The conventional voltage of each circuit has 12V, 5V, 3.3V, 2.5V, 1.5V, 1.2V, 1V etc. in interchanger.Common voltage
Normal range (NR) is as shown in table 2.
The common power voltage references normal range (NR) of table 2
| Sequence number | Supply voltage | Term of reference |
| 1 | VDD_12V | 11.4-12.6 |
| 2 | VDD_5V0 | 4.75-5.25 |
| 3 | VDD_3V3 | 3.135-3.465 |
| 4 | VDD_2V5 | 2.375-2.625 |
| 5 | VDD_1V5 | 1.425-1.575 |
| 6 | VDD_1V2 | 1.14-1.26 |
| 7 | VDD_1V0 | 0.97-1.03 |
For example：When the supply voltage that a certain circuit needs is 12V.If now detect actual supply voltage being higher than
12.6V.Control unit controls power-off, prevents that electronic component is caused to damage due to overtension.If now detected
To real-time supply voltage be less than 11.4V, brownout can cause interlock circuit due to voltage supply deficiency cisco unity malfunction, now
Need control unit control power reset, if reset three times after still can not reach normal range value, closing power supply will be carried out
Operation.
In addition to the value to power supply carries out corresponding collection, the POWERGOOD pin level to power module has been also carried out phase
The collection answered.
The reset of cpu chip is implemented, and mainly after exception occurs in CPU, control unit carries out operation to CPU recovers it
Corresponding function.
The reset of forwarding chip is implemented, and mainly after exception occurs in forwarding chip, control unit is carried out to forwarding chip
Operation makes it recover corresponding function.
