In the case of, it is powered on to hard disk, to ensure that the safety of hard disk.
As shown in Fig. 2, another embodiment of the present invention provides a kind of method that server node hard disk powers on, this method
It may comprise steps of：
Step 201：It is powered on to the power supply copper bar of cabinet, power supply all nodes of copper bar is made to provide operating voltage.
In this step, operating voltage need to be provided for other all nodes by power supply copper bar, only first on cabinet
Electricity, the power supply copper bar that could pass through cabinet generate voltage.
Wherein, the power supply copper bar of cabinet is equivalent to a power supply, as long as powering on to cabinet, will provide lasting
12V voltage.
Step 202：Press power button, system detection mainboard signal in place and mainboard starting-up signal.
In this step, complete by artificially pressing power button under the premise of the power supply copper bar of cabinet provides operating voltage
The detection of pairs of mainboard signal in place and mainboard starting-up signal, therefore when mainboard carries out installing component, it can be in advance from the master
Mainboard signal wire in place and mainboard starting-up signal line are drawn on plate.Drawing signal wire in advance, specific step is as follows：
Mainboard signal in place and the corresponding port of mainboard starting-up signal are found on the main board；
The two ports are coupled with two conducting wires；
It is welded with solder stick in the place of two ports and conductive contact.
And in order to carry out facilitating expressions to detection signal, can be selected setting representation expression mainboard signal in place and
Mainboard starting-up signal.Wherein, the representation of setting can be arbitrary form, can also be selected according to user.Example
Such as, mainboard signal in place is indicated with " Present ", and mainboard starting-up signal is indicated with " Power-on ".
As a result, after pressing power button, system can detect board status, actively exported by mainboard Present signal and
Power-on signal.
Step 203：Isolation processing is carried out to the mainboard signal in place and mainboard starting-up signal by MOS.
In this step, after detecting the mainboard of present motherboards signal in place and mainboard starting-up signal, to effectively prevent
The string of power panel and mainboard electricity, the signal that need to will test carry out isolation processing, avoid that in place or mainboard is not in mainboard with this
In the state of booting, so that hard disk powers on.Therefore, in power panel installing component, at least two can be arranged on power panel in advance
It is MOS a, and the mainboard drawn on mainboard signal wire in place and mainboard starting-up signal line are connected respectively to the two MOS
Input port.The signal wire that mainboard is drawn connect with MOS input ports to specific step is as follows in advance：
Two MOS are at least arranged on power panel, and determines two MOS input ports；
The mainboard drawn on mainboard signal wire in place is connected to the first MOS input ports；
The mainboard starting-up signal line drawn on mainboard is connected to the 2nd MOS input ports；
It is welded with solder stick in the place that two conducting wires are contacted with corresponding MOS input port.
And for the purposes of facilitating expression to the signal after isolation, the representation of setting can be selected, successively indicate to pass through
Mainboard signal in place and mainboard starting-up signal after MOS isolation processings.Wherein, the representation of setting can be arbitrary shape
Formula can also be selected according to user demand.For example, the mainboard signal in place after isolation processing uses " Present_R "
It is indicated, the mainboard starting-up signal after isolation processing is indicated with " Power-on_R ".
Therefore, after system detection to mainboard signal in place and mainboard starting-up signal, the process very short processing time, first
MOS output treated mainboard signals in place, the 2nd MOS mainboard starting-up signals that export that treated.
Step 204：The two MOS output logical values are judged using XOR gate.
In this step, after mainboard signal in place and mainboard starting-up signal that isolation processing is exported by MOS, to look into
See whether mainboard is in place and whether mainboard is switched on, at least one XOR gate need to be arranged, thus to export after isolation processing
Logical value is judged.Therefore, in power panel installing component, at least one NOR gate circuit should be preset, while by MOS
Two output leads of door are connected to the input port of XOR gate.In advance by two MOS output leads and NOR gate circuit
Input port connection specific step is as follows：
One XOR gate is at least set on power panel, and determines two input ports of XOR gate；
Determined on power panel the first MOS output port, the 2nd MOS output ports；
Two conducting wires are selected, are coupled with the first MOS, the 2nd MOS corresponding output ports, and connected with solder stick
It is welded at place；
The other end of two conducting wires is connected respectively to two input ports of XOR gate, and is being connected with solder stick
It is welded at place.
Therefore, by the logic judgment of XOR gate, could be aware that mainboard, whether in place and mainboard is switched on.
In order to be indicated to the signal that logic judgment exports, representation can be selected according to user demand.Example
Such as, it is indicated by the signal that XOR gate logic judgment exports with " P12V&P5V_EN ".Wherein, the output signal is as electricity
The enable signal of flat conversion chip.
Further, signal detection logic circuit in place can be arbitrary logic circuit, and the number of logic circuit is extremely
Less it is one, can also be selected according to the demand of user.For example, " with door ", disjunction gate, " exclusive or can be selected in logic circuit
The logic circuit of the diversified forms such as door ", " same or door ", non-conjunction.Signal detection logic circuit in place in the embodiment of the present invention
For " XOR gate ", by the corresponding relationship of the input and output of " XOR gate " logic unit, i.e., when XOR gate exports logical value
When being 1, it is determined that present motherboards are in place and mainboard is switched on, to power on to node hard disk.
Step 205：The enable signal that XOR gate exports is respectively transmitted to the enable signal to two electrical level transferring chips
End.
In this step, after the logical value of XOR gate output judgement, turned by the signal control level that makes can control exported
Change whether chip works.Therefore, in power panel installing component, two electrical level transferring chips should be at least set in advance, and
And the enable port of the enable signal of XOR gate output and electrical level transferring chip is attached.Concrete operation step is as follows：
Two electrical level transferring chips are at least set on power panel, and determine the enabled control terminal of two electrical level transferring chips
Mouthful；
The output port of XOR gate is determined on power panel；
Two conducting wires are selected, and two conducting wires are connected to the same output port of XOR gate, are being connected later with solder stick
It is welded at place；
The other end of two conducting wires is coupled with to the enable port of two electrical level transferring chips, and is being connected with solder stick
It is welded at place.
As a result, using the signal of XOR gate output as the enable signal of electrical level transferring chip, it is divided into two-way transmission, for convenience
Illustrate, this two-way enable signal is represented by " P12V_EN " and " P5V_EN ", and signal P12V_EN and signal P5V_EN is distinguished
It is input to the enable end of electrical level transferring chip, to control the working condition of electrical level transferring chip.
Step 206：The working condition of electrical level transferring chip is controlled by enable signal, it is determined whether power on to hard disk.
In this step, it after electrical level transferring chip receives enable signal, can be determined according to the logical value of enable signal
Whether chip carries out level conversion.Specific step is as follows for corresponding signal wire connection：
The output port of two electrical level transferring chips is determined respectively；
Determine two voltage input ports of hard disk backboard；
Two conducting wires are selected, and one end of two conducting wires is coupled with to two voltage output ports of electrical level transferring chip,
It is welded later with solder stick in the junction of port；
By another voltage input port for terminating to hard disk backboard of two conducting wires, and welded with solder stick.
It may choose whether by logic judgment to hard disk according to the state-detection that present motherboards are in place and are switched on as a result,
It powers on.In embodiments of the present invention, when the logical value of enable signal is 1, electrical level transferring chip carries out level conversion, to give
Node hard disk powers on；When the logical value of enable signal is 0, electrical level transferring chip is without level conversion, thus can not be to section
Point hard disk powers on.Wherein, it for convenience of expression, is denoted as respectively by two voltage signals that two electrical level transferring chips export
" P12V_HDD " and " P5V_HDD ".
Further, when carrying out level conversion, the chip of level conversion can be arbitrary conversion chip, can also according to
Family demand is set.For example, electrical level transferring chip optional " 74LVC4245A ", " MAX3370 " and " NLSX4373 " etc. is more
The chip of seed type carries out level conversion, operating voltage needed for output node hard disk, thus in node by the chip of selection
In the case that mainboard is in place and mainboard is switched on, powered on to node mainboard.
It is 12V and 5V by the voltage that electrical level transferring chip exports, the supply voltage of 12V is mainly used for as magnetic head
The bigger device of these power consumption, the supply voltage of 5V be mainly used for as resistance, some logic unit sum number electricity modules these
The smaller device of power consumption, if using the supply voltage of 12V without level conversion, be easy to causeing a large amount of power consumption,
And very likely these devices are caused centainly to damage because flowing through these little modules or the electric current of resistance is too big.
