The network card is managed out of band by the server, and an engineer can manage and maintain the server at any place through network connection without going into a laboratory machine room through out-of-band management. NCSI (Network Controller Sideband Interface) is a signal Interface for realizing out-of-band management of a server.
To meet the various configuration needs of customers, such as: some configurations require that the NCSI is connected out through the front IO, and some configurations require that the NCSI is connected out through the rear IO, but only one interface for the NCSI to be led out from the BMC is provided, and the front-out and the rear-out of the NCSI are considered at the same time, so that the wiring length of the NCSI on the board can exceed 10 inches, and the length of the NCSI cable also exceeds 10 inches generally. The length of the NCSI signal wiring on the network card is not calculated, the length of the NCSI wiring of the BMC on the mainboard and the length of the corresponding cable exceed 20 inches, and the design requirements of the NCSI on a BMC manual are exceeded. The mainboard of different manufacturers can adapt to the network cards of different manufacturers, and the wiring length of the other party is unknown when the mainboard and the network cards are designed.

Specifically, the establishing and holding time of the BMC NCSI RX signal on the motherboard cannot be kept to meet the timing requirement, but the delay of the intelligent network card connected to the NCSI cannot be adjusted to meet the timing requirement of the RX signal at the BMC receiving terminal. Therefore, the fixed delay of the NCSI signals of the network cards of different manufacturers is not exactly the same, so that the NCSI signal timing sequence on the motherboard hardly has a uniform delay value.
Therefore, how to implement automatic adjustment of the NCSI signal of the network card to adapt to network card devices of different manufacturers to implement stable communication of the network card is a problem to be solved urgently.

The NCSI signal of the BMC is directly connected to the network card PHY through a cable, or is connected to the network card PHY through a cable through a switch. However, since the total routing of the NCSI on the motherboard and the network card is too long, and the NCSI link parameter is fixed, that is, the delay value of the timing sequence is fixed, the setup holding time of the NCS signal receiving end of the server does not meet the timing sequence requirement, which may cause a failure in the network card adaptation.

Step 6: the CPLD saves the current NCSI delay value in the FLASH of the CPLD.
And 7: the clock is continuously adjusted forward or backward by 0.1ns based on the current delay time as the current NCSI delay value, and goes to step 2.
The embodiment provides an automatic adjustment method for an NCSI signal of a network card, which adjusts the NCSI signal timing delay through a CPLD, stores the adjustment parameters and the ID information of the network card in a FLASH of the CPLD in a one-to-one correspondence manner, determines the delay value through the ID information of different network cards after the system is started, and then realizes the adaptation and normal communication of the network card.
Example two:
based on the first embodiment, the present embodiment further discloses an automatic adjustment method for a network card NCSI signal, including:
1. when the network card is used, the network card is divided into a network card NCSI (network interface card network interface Standard) adaptation mode and a network card normal use mode, wherein the network card adaptation mode is used for adjusting the time sequence delay, and the network card normal mode is used for normal communication of the network card. The BMC can set a network card adaptation mode into an automatic adaptation mode and a manual adaptation mode.
2. After the BMC sets the manual adaptation mode, an engineer may manually set the NCSI delay parameter on a management page of the BMC, may input intervals of delay adjustment to be 0.1ns, 0.2ns, 0.3ns, and the like, and a range size of the delay adjustment, and transmit the interval and the range size to the CPLD through I2C to perform corresponding adaptation operation. The BMC web page management interface can display the adjusted NCSI timing sequence for reference. After the CPLD adaptation is completed, the delay parameters are stored in the flash, and the network card can normally communicate.
3. After the CPLD adaptation is completed, the delay parameters are stored in the FLASH of the CPLD, the BMC is set to be in a network card normal use mode, and the network card can normally communicate.
4. After the BMC sets the automatic adaptation mode, the CPLD judges whether a corresponding network card NCSI delay value exists or not according to the ID value of the network card acquired from the BIOS.
5. If the corresponding NCSI delay value is stored in the FLASH of the CPLD, the CPLD works in the normal mode of the network card, the NCSI delay value is read, and the network card can normally communicate.
6. If the FLASH of the CPLD does not have a corresponding NCSI delay value, the CPLD collects a data signal sent from a network card in a working network card adaptation mode, after receiving the original data of the NCSI signal, the BMC sends out a ping command by delaying the clock relative to the data for 0.1ns forwards or 0.1ns backwards, and if the clock can ping is passed, the BMC carries out a pressure test of the network card downwards. And after the pressure test is passed, the CPLD stores the adjusted NCSI delay parameters in FLASH. If the pressure test of the network card does not pass the description and the time sequence does not meet the requirement, continuing to advance or retreat for delay, and adding an adjustment interval of 0.1ns on the basis of the last time for each adjustment. The delay interval time of each adjustment and the overall adjustable delay range can be manually modified at the management interface of the BMC. The BMC transmits the adjusting parameters to the CPLD through the I2C, the CPLD transmits the finally adjusted time sequence parameters to the BMC, and a management interface of the BMC can view the drawn NCSI time sequence diagram. When the server inserts the network cards of different manufacturers and different models, the CPLD stores the manufacturer and model information of the network cards and puts the manufacturer and model information and the adjusted delay value into a table.
After the network card adaptation is completed, the server is set to be in a normal use mode, and the CPLD reads delay values corresponding to different network cards to adjust the NCSI time sequence so as to realize the stable and reliable operation of the network card.
