Description
Technical field
The present invention relates to a kind of server fan replacing options and fan power supply systems.
Background technique
Server is a kind of high-performance computer, service can be externally provided by network, relative to common computer, service
Device has the characteristics that supercomputing, uninterrupted reliability service, powerful data throughput capabilities.Server is in the process of running, interior
Portion can constantly generate heat, increase the temperature of electronic component constantly, influence server normal operation, therefore lead in server
Domain, heat dissipation design are vital.
Fan is the common radiator in server field, its effect is to be taken heat outside server to by air-flow
Portion guarantees server reliably continuous operation.In general, fan has a branch of overhanging conducting wire, wire end is provided with fan terminal,
Fan terminal is inserted into the connector on circuit board of server, and the electric signal on circuit board is imported fan, drives wind
Fan rotation, realizes heat sinking function.
The feeder ear of server fan generally can all use the protection chip with switch and overcurrent protection function, in fan
Electric current be more than normal range (NR) when disconnect fan supply access, prevent the generation for burning the major accidents such as element.Due to server
Uninterrupted reliability service is needed, when the fan of server breaks down, needs to carry out in the case where server is switched on and runs
Replacement, that is, so-called hot swap.Fan hot swap is divided into heat and removes and heat two processes of addition.Heat is being carried out more to fan
Change, especially hot addition when, very big electric current can be generated in fan route, this electric current is usually fan running current
Several times.This electric current can be more than the overcurrent protection setting value of protection chip, so that chip is made to turn off fan power supply line, it is hot in this way
Fan in addition can not work normally.
Summary of the invention
It, can be with the technical problem to be solved by the present invention is to propose a kind of server fan replacing options and fan power supply system
It realizes that server replaces failure fan in the case where normal boot-strap is run, can effectively improve the reliability and stabilization of server
Property, the hot swap of server fan is realized using few component, and all avoid fan terminal and leaving or contacting wind
The moment of sash connector generates excessive electric current, so that protection chip triggers overcurrent protection, fan is caused to be unable to operate normally.
One fermentation of the present invention provides a kind of server fan replacing options, comprising the following steps:
Whether detection fan breaks down, if fan breaks down, then carries out fan replacement；
The removal of failure fan is first carried out, after fan leaves connector, fan power supply line is disconnected, and is stopped as fan connection
Then fan is added in device power supply, after fan is inserted into connector, the conducting of fan power supply line is powered for fan.
Further, whether the detection fan, which breaks down, specifically includes: whether detection rotation speed of the fan is zero, is zero
Represent fan failure.
Further, described after fan leaves connector, fan power supply line disconnects, and stops as fan connector power supply
It specifically includes:
Fan connector can export fan signal in place, after fan leaves connector, the wind of fan connector output
Fanning signal in place becomes high level from low level, becomes low level from high level by the enable signal exported after phase inverter,
Make to protect chip shutdown, fan power supply line disconnects, and input power stops being that fan connector is powered.
Further, after the fan insertion connector, the conducting of fan power supply line specifically includes for fan power supply:
After fan is inserted into connector, the fan signal in place of fan connector output becomes low level from high level, passes through
The enable signal exported after phase inverter becomes high level from low level, makes to protect chip conducting, the conducting of fan power supply line is defeated
Enter power supply to start as fan connector power supply.
Further, BMC detects whether rotation speed of the fan is zero, when being zero, shows that fan breaks down, BMC notifies system
Replace fan.
Another aspect of the present invention additionally provides a kind of fan power supply system, including input power, protection chip, fan electricity
Source, fan connector, phase inverter and BMC, they are all disposed on server master board；
With protection chip connection input power and fan power supply with switching function；
The on-off for the enable signal control protection chip that the signal in place of fan connector output generates after phase inverter,
When enable signal is high level, protection chip conducting, when enable signal is low level, protection chip shutdown；
The fan rotating speed signals of fan connector output are connected to BMC, and BMC judges that fan is by received tach signal
No normal work, when detecting fan rotating speed signals exception, BMC is notified that system fan breaks down, and needs replacing use.
Further, protection chip has overcurrent protection function, and overcurrent protection function is when the electric current for flowing through protection chip
When more than setting value, protection chip shutdown, in case of overcurrent protection, it is necessary to which carrying out reboot operation to server can just make to protect
Chip restores normal function.
A kind of server fan replacing options of the present invention and fan power supply system may be implemented server and transport in normal boot-strap
Failure fan is replaced in the case where row, can effectively improve the reliability and stability of server, it is real using few component
The hot swap of server fan is showed, and it is excessive in the moment generation for leaving or contacting fan connector all to avoid fan terminal
Electric current so that protection chip trigger overcurrent protection, cause fan to be unable to operate normally.
Detailed description of the invention
Fig. 1 is the flow chart of server fan replacing options；
Fig. 2 is the structure chart of fan power supply system；
Specific embodiment
