Example 3

FIG. 8 is a schematic diagram of a connection relationship between an optical module interrupt line and a logic device according to an embodiment of the present invention. As shown in FIG. 8, the present embodiment provides a set of IIC interface for accessing an optical module internal register. On the hardware connection, the connection of the interrupt signal line is discarded, and the logic device is connected to the logic device by the high level of the bit signal line. In the logic device register setting, the interrupt register is discarded, and the in-position status register is used to focus on whether the optical module is in place or not, and whether the optical module has an interrupt signal output. Based on the above circuit connection, the processor polls the in-position condition of the optical module at intervals, and continues to poll for the optical module that is not in position, and performs the operation of reading the internal abnormal register of the optical module for the in-position optical module. When an optical module abnormal register is read as abnormal or the IIC access fails, it is directly reported to the user.

There are many standards for optical modules. This example uses the parallel optical module CXP under the InfiniBand architecture as an example. However, it is only an example. In the practical application of this solution, it is not limited to such optical modules. Other standard optical module devices can be used. This technical solution is implemented.

The optical module is connected to the logic device through the IIC bus, and all optical modules have independent IIC interfaces connected to the logic device. The logic device is connected to the processor through a parallel data bus and an address bus, and the processor can access registers internal to the logic device through the data bus and the address bus. The in-position signal of the optical module is connected to the logic device. The optical module's in-position signal is pulled high.

Through the hardware scheme of the embodiment, the interrupt signal line in the related art is omitted in the circuit connection, and only the in-position signal line is used. The in-position signal is connected to the high level through the resistor. When the optical module is inserted into the optical port, since the level is pulled down to the low level by the optical module housing, the corresponding module can be read and read in the corresponding optical module in the bit register. Information is changed from in place to in place.

The above is the hardware connection scheme, the software scheme is as follows:

A set of registers is defined internally by the logic device to store the in-position information of the optical module. The in-position signal of the optical module is usually high when the optical module is not plugged into the interface, and is usually low when the interface is inserted. The current level value of the bit signal of all optical module interfaces is stored in the register, with 0 being the optical module in place and 1 being the optical module not in the bit. deal with The device can simulate the timing of accessing the optical module IIC interface by reading and writing the registers of the logic device. The processor can read the internal registers of the optical module in the above manner. The internal register of the optical module must be a register that stores the abnormal state of the optical module. This register stores the abnormality of the optical module. The processor polls the in-position register at intervals to obtain the optical module in-position state of all current optical ports. The register value is not in bit (1), and the above polling in-place register operation is repeatedly executed. The register value is in bit (0), and the processor accesses the optical module's exception register through the logic device. If the above register value is not abnormal, the above polling in-place register operation is re-executed. If the above register value is abnormal, the exception information is first reported, and then the polling in-place register operation is re-executed.

According to the solution provided by the implementation, the number of signals connected to the logic device by the optical module can be reduced first, and the interrupt signal can be disconnected, and the processor does not need to specifically open the interrupt response process and related registers for the optical module. The in-position signal line is less susceptible to interference with respect to the interrupt signal line because the signal changes level only when the optical module is inserted or removed from the system board. Even if a misjudgment occurs in the case of external interference, the optical module that is not in place is considered to be in place, and subsequent access to the optical module register through the IIC interface immediately finds that the optical module is actually absent, and the reliability is higher than the common scheme. It should be noted that, for the foregoing method embodiments, for the sake of simple description, they are all expressed as a series of action combinations, but those skilled in the art should understand that the present invention is not limited by the described action sequence. Because certain steps may be performed in other sequences or concurrently in accordance with the present invention.

The apparatus of claim 7, wherein the optical module is coupled to the logic device by a bit signal line. The apparatus according to claim 8, wherein when the level signal is a low level signal, the second obtaining module comprises: a first reading unit configured to read state information stored locally by the optical module; The reporting unit is configured to report status information of the abnormality when the status information is abnormal; The second reading unit is configured to continue to read the state information stored locally by the optical module when the state information is not abnormal. The apparatus of claim 8 wherein said apparatus further comprises: The third obtaining module is configured to periodically acquire a signal for indicating an in-position state of the optical module when the level signal is at a high level.
