At this time, as shown in the following [Table 2], the overlap region of the command region used in the PMBus mode and the PSMI mode is in the range of D0h to DFh.

Accordingly, the command region is selected as one of the regions in the range of D0h to DFh as a common command and the selection signal is included in the command of the selected region.

For example, when the local monitoring unit 300 or the remote monitoring unit 320 communicating in the PMBus mode wants to know the current temperature detected by the first sensor of the PSU module 100, the local monitoring unit 300 or The remote monitoring unit 320 includes a selection signal for selecting the PMBus mode in one of the commands in the D0h to DFh region. At this time, since the selected command is composed of 8 bits, as shown in FIG. 8, a selection signal for selecting PMBus mode or PSMI mode is included for each bit as shown in Table 3 below.

At this time, the PEC (Periodic Error Correction) of Bit 2 periodically checks the command to determine whether there is an error, and if the Bit 2 has a value of '1', periodically checks the transmitted command to prevent an error. Do it.

That is, if the command has a value of '10101000', the first selector 230 of the system 200 to which the command is applied selects the first PMBus handling unit 240 and the PSU module 100.

Also, a signal for selecting the first and second PMBus handling units 240 and 120 or the first and second PSMI handling units 250 and 130 as a reserved that is a region other than the command region. Can also be used. That is, the handling unit is selected using a reserved area that is an area other than the command area of Table 2 (PMBus mode is in the range of 05h to 0Fh, and PSMI mode is in the range of 1Ah to 1Fh). The selection method at this time is the same as the method using the common command region.

As described above, when any one of the first and second PMBus handling units 240 and 120 or the first and second PSMI handling units 250 and 130 is selected and a communication mode is selected, communication is performed through the selected mode. The PSU module 100 may be managed by the local monitoring unit 300 or the remote monitoring unit 320 (S430).

On the other hand, as shown in Figure 9 showing a modification of the system management apparatus according to the present invention, the system 200 and the PSU module 100 directly connected to the hardware (Hardware) 220a low use frequency The communication mode can be selected using a signal, for example, SMBAlter #, which is an interrupt signal, or SDA or DCL, which is a signal for confirming whether a command is transmitted.

That is, the system driver 220 of the system 200 and the second selector 140 of the PSU module 100 are directly connected, and the first and second selectors 230 of the system driver 220 are connected. The controller 140 selects one of the first and second PMBus handling units 240 and 120 or the first and second PSMI handling units 250 and 130 by transmitting a selection signal to the first and second PMBus handling units.

In this case, the selection signal transmitted from the system driver 220 generates the selection signal through a toggle number, a byte, or a nibble of the signal, as shown in FIG. 10 and Table 4 below. do.

That is, when using the interrupt signal SMBAlter # as a selection signal and selecting the PMBus mode by using a toggle ("A"), generating and transmitting three toggle numbers of the SMBAlter # signal and selecting the PSMI mode. Generates 7 toggle numbers of SMBAlter # signals and sends them. In addition, when the PMBus mode is selected using bytes, the SMBAlter # signal is transmitted to 'OxA5', and when the PSMI mode is selected, the SMBAlter # signal is transmitted to 'Ox5A' so that the first and second PMBus handling units 240 and 120 or the Any one of the first and second PSMI handling units 250 and 130 may be selected.
