South Bridge chip with all have special Wake# pin to communicate for both on network interface card, wherein, the Wake# pin of network interface card
Waking up wake signal up for sending to the Wake# pin of South Bridge chip, then South Bridge chip responds, and realizes network and call out
Wake up, i.e. remote opening.
Step 702: GPIO1 pin, the IANDIS1 of network interface card with South Bridge chip connects respectively by N-type 2N7002MOS pipe in advance
Mouth and P3V3 supply module are connected.
As it is shown in fig. 7, a kind of system realizing WOL, including: realize server 601 and the exterior tube of WOL
Reason server 602, wherein, it is achieved the server 601 of WOL, includes again: South Bridge chip 6011, network interface card 6012, N-type
Isolation circuit, P3V3_AUX supply module 60141 and the 4.7k resistance that 2N7002MOS pipe 60131 forms with 4.7k resistance 60132
The drive circuit that the control circuit of 60142 compositions and P3V3_AUX supply module 6016 form with 4.7k resistance 6017.At this
In bright embodiment, it is with a pin of South Bridge chip 6011 correspondence as GPIO1 and 1 interface of network interface card 6012 correspondence is
As a example by IANDIS1.
So concrete connection procedure is as follows: the S pole of N-type 2N7002MOS pipe 60131 is connected to South Bridge chip 6011
On GPIO1 pin, D pole is connected on the IANDIS1 interface of network interface card 6012, and G pole is connected to by the resistance 60132 of a 4.7k
On P3V3 supply module 6015.
Step 703: in advance P3V3_AUX supply module is connect with the IANDIS1 of network interface card by the pull-up resistor of a 4.7k
Mouth is connected, and is connected in parallel with N-type 2N7002MOS pipe.
In the embodiment shown in fig. 7, P3V3_AUX supply module 60141 is electric with the control of 4.7k resistance 60142 composition
Road is as follows with the concrete connection procedure of other parts: first by P3V3_AUX supply module 60141 and 4.7k resistance 60142 phase
Even, then the other end of 4.7k resistance 60142 is connected with the IANDIS1 interface of network interface card 6012 by a wire, and realizes
The most in parallel with the D of N-type 2N7002MOS pipe 60131, the most all it is connected with IANDIS1 interface, the physical circuit form after connection can
In the figure 7 it is evident that do not repeating.
Step 704: in advance wire is connected on the extranets card interface that IANDIS1 interface is corresponding, this interface carries out
WOL.
The interface of the most corresponding outside of each interface of network interface card, for being connected with outer lead, then the present invention
Embodiment is just as a example by IANDIS1 interface is used for realizing calling function of network.
Step 705: the server for WOL to be achieved leads to 220v alternating current in advance.
Owing to the server of WOL to be achieved not having supply module to provide running voltage for it, therefore should be in advance
This server provides 220v alternating current, then will make the P3V3 supply module powered for other parts on mainboard in Fig. 7
The voltage of 6015 is 0v, and is that the P3V3_AUX supply module 6016 and 60141 that on mainboard, other parts are powered just has 3.3v
Supply voltage.
Step 706:N type 2N7002MOS pipe receives the low level that P3V3 supply module provides.
Because being in the WOL stage, then realize the server 601 of WOL and be not keyed up, therefore in Fig. 7
P3V3 supply module 6015 on voltage be always 0v in this stage, say, that P3V3 is loaded into N-type in this stage
The voltage that the grid voltage of 2N7002MOS pipe G pole provides is 0v all the time, and generally, voltage 0～0.7v voltage meeting
Being considered as low level, therefore receive the offer of P3V3 supply module in this stage G pole is always low level.
Step 707:N type 2N7002MOS pipe ends, and blocks the connection of GPIO1 pin and IANDIS1 interface.
The G pole of N-type 2N7002MOS pipe, after receiving the low level that P3V3 provides, is either connect by the S pole of metal-oxide-semiconductor
Receiving high level or the low level of the output of GPIO1 pin, metal-oxide-semiconductor all can end, and this is that the conducting principle according to metal-oxide-semiconductor determines
, because only that when the level of G pole is higher than the level of S pole, metal-oxide-semiconductor just can turn on, and otherwise, all can end, and at this
In inventive embodiments, as long as after G pole receives low level, the level that S pole receives all can be lower than the level of G pole or the same, this
Two kinds of situations are all unsatisfactory for the condition of metal-oxide-semiconductor conducting, and therefore, N-type 2N7002MOS pipe ends, and manage due to N-type 2N7002MOS again
It is attached between South Bridge chip and network interface card, so because metal-oxide-semiconductor ends, has just blocked the connection of South Bridge chip and network interface card,
If thus the GPIO1 pin on South Bridge chip is extremely, and during output low level, the duty of network interface card would not be affected.
Step 708:P3V3_AUX supply module is the IANDIS1 interface on network interface card with the control circuit of 4.7k resistance composition
High level is provided.
During the WOL shown in Fig. 7, it is achieved the server 601 of WOL is in holding state, because of
For server does not has the power supply unit that battery etc. is powered for server, therefore, if it is desired to realize remote server start, that
This server must have turned on 220v alternating current, and P3V3_AUX supply module 60141 is to connect 220v exchange
Will exist after electricity, and voltage is 3.3v, in the ordinary course of things, voltage can be considered as high at the voltage of 2.2～3.3v
Level, therefore will pass through 4.7k resistance 60142 at this stage P3V3_AUX supply module 60141 be network interface card 6012
IANDIS1 interface provides high level all the time, thus is effectively ensured in the WOL stage, and this interface is the most effective such that it is able to
Realize calling function of network.
In addition, P3V3_AUX supply module 6016 and resistance 6017 as the drive circuit in the embodiment of the present invention,
For improving the driving force of South Bridge chip 6011.
Step 709:IANDIS1 interface high level, and receive the special data package that external management server sends.
When, after the IANDIS1 interface on network interface card to high level, network interface card will respond, thus receives external management
The special data package that server 602 sends, say, that network interface card 6012 can carry out WOL according to this special data package.
Step 710: check the MAC Address having current network interface card corresponding in special data package.
After network interface card 6012 receives special data package described above, the content that can comprise this special data package is carried out point
Analysis processes, because user is the remote opening wanting to realize a certain server targetedly, then in the ordinary course of things, and these data
Bao Zhonghui accurately comprises the MAC Address of network interface card 6012 correspondence.Analyze and process at network interface card 6012 and determine the MAC ground containing its correspondence
Behind location, such as, the address comprised, as corresponding MAC Address, is 00-23-5A-36-54-62, and then, network interface card is the most permissible
Wake-up signal is sent to South Bridge chip.
Step 711: network interface card sends one by the Wake# pin on the Wake# pin south bridge chip on network interface card and wakes up up
Wake signal.
After network interface card 6012 determines MAC Address, it is possible to utilize special pin to carry out WOL, by network interface card 6012
On Wake# pin export its send wake up the wake signal Wake# pin to South Bridge chip up.
Step 712: the Wake# pin on South Bridge chip receives after waking up wake signal up, response, it is achieved current server
WOL.
Step 713:N type 2N7002MOS pipe receives the high level that P3V3 supply module provides, as the GPIO1 of South Bridge chip
During pin output high level, perform step 714, when the GPIO1 pin output low level of South Bridge chip, perform step 717.
Realizing WOL, i.e. after Server remote start, the P3V3 supply module that mainboard is powered for other parts
6015 will be become 3.3v from 0v, and that is according to the corresponding relation of low level described above Yu voltage, and P3V36015 can be metal-oxide-semiconductor
The G pole of 60131 provides high level, now according to the output of different GPIO1 pins, should discuss respectively.When GPIO1 pin
During output high level, perform step 714.
Step 714:N type 2N7002MOS pipe is in cut-off state, blocks the circuit of GPIO1 pin and IANDIS1 interface even
Connect.
This step is identical with the principle described in above-mentioned steps 707, is not repeating.
Step 715:P3V3_AUX supply module continues through resistance and provides high level for IANDIS1 interface.
Leading to 220v alternating current to server, and after realizing WOL, this P3V3_AUX supply module 60141 or it
The voltage of front 3.3v, also according to the corresponding relation of high level Yu voltage, determines that P3V3_AUX60141 continues as IANDIS1
Interface provides high level.
Step 716: the high level that the IANDIS1 interface P3V3_AUX supply module of network interface card provides, it is achieved this interface
Enable, i.e. can use this interface, and terminate current process.
After realizing WOL, IANDIS1 interface is by receiving high level, it is achieved that the enable of this interface, thus
In the application such as data communication afterwards or WOL, IANDIS1 interface can continue to use.
Step 717:N type 2N7002MOS pipe is in the conduction state, and connection GPIO1 pin connects with the circuit of IANDIS1 interface
Connect.
After realizing WOL, owing to the G pole of N-type 2N7002MOS pipe 60131 receives high level, and S pole receives low
After level, because G pole level is higher than S pole level, so metal-oxide-semiconductor 60131 will realize conducting by parasitic diode therein,
Thus the circuit between South Bridge chip 6011, metal-oxide-semiconductor 60131 and network interface card 6012 is connection.
Step 718: by the above-mentioned circuit of connection, the low level of GPIO1 pin output will drag down P3V3_AUX and power mould
High level on block.
In the circuit of connection, as long as at one being low level, other is the most all low level, thus P3V3_AUX supplies
The high level that electricity module 60141 is provided for IANDIS1 interface by resistance 60142 will be pulled low.
Step 719:IANDIS1 interface low level, it is achieved this interface disables.
