In other words, the order of accessing the resources of the second system 200 in the first system 100 is as follows.

First, an input / output cycle generated from the first processor 101 is interpreted by the first interface unit 102, and an input / output cycle according to this is generated and transmitted to the first control unit 103.

Then, the first controller 103 controls two first and second I2C controllers 104 and 105 to access resources of the other system, where the first controller 103 controls the two first and second 2, a selection signal for selecting the second I2C control section 104, 105 is generated.

The first second I2C control unit 104 and 105 selected by the selection signal interpret the request requested by the first control unit 103 and change it into an I2C bus protocol to convert the first and second I2C bus 106 into a second I2C bus 106. The command is transmitted through 107.

Commands selectively transmitted via the first and second I2C buses 106 and 107 are the third and fourth I2C buses 206 and 207 of the other system 200 that are line-crossed via the connector 300. Is transmitted to the second control unit 203 of the other system 200 and simultaneously to each module 208-211 of the other system.

Accordingly, each module 208-211 decodes a command transmitted from the first system 100 and responds correspondingly.

The response obtained from each module 208-211 in the second system 200 thus obtained is again via the third and fourth I2C buses 206 and 207 and via the connector 300 the first system. The first system 100 controls and states the resources of the second system 200 by being transmitted to the first and second I2C buses 106 and 107 in the 100 and then to the first control unit 103. Checking is possible.

Here, the status check for the resource is the presence of the processor, the operating state of the system, whether the fan is operating normally, the display state of the LCD panel, whether the UPS is operating.

As described in detail above, the present invention has the effect of providing convenience in recovering the system failure by cross checking each other system by mutually connecting internal resources by interconnecting the I2C bus between two systems having the same structure.

In addition, there is a function of checking the state of each other between the two systems, it is also effective to improve the reliability of the system.
