[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure and operation of an embodiment of the present invention will be explained in detail using FIGS. 1 to 4. Figure 1 (a)
, the remote power-on control unit 1 detects a power-on instruction command (see FIG. 4) received via a line and captures additional information added to the command.

The register 2 is a register that temporarily holds data when communicating with a line. memory 3
is a memory that stores additional information received via the line. The CPU 4 is a processor that performs various controls. Register 5 is a register for transmitting and receiving data via the bus.

The bus control switch 6 is a switch that bypasses the path within the remote power-on control unit 1 and connects the communication processor (CP) 10 to a line. The system power control section 7 turns on the power of the CPU 9, holds additional information notified from the remote power-on control section 1 in the memory 8, and so on.

The CPU 9 is a central processing unit that performs various processes, and performs various processes after performing IMPL, IPL, etc. A communication processor (CP) 10 sends and receives data between the CPU 9 and other devices via a line. Here, when the processing according to the IMPL, IPL, and additional information of the CPU 9 is completed, it is notified to that effect and the bus control switch 6 is switched, and in this switched state, it is connected to other devices via the line. It is used to send and receive data (communication).

FIG. 1B shows a configuration in which a remote power-on function 12 is provided within the communication processor 11. This is the function of the remote power-on control unit 1 in (a) of FIG.
It is provided within the communication processor 11, and its operations are the same. The configuration shown in FIG. 1(A) will be explained below.

Next, the operation of the configuration shown in FIG. 1 (a) will be explained in detail using FIG. 2. In FIG. 2, S1 determines whether there is an instruction to turn on the power. This is (a) in Figure 1.
It is determined whether the remote power-on control unit 1 has received a power-on command (see FIG. 4) via the line. YE
In the case of S, the additional information present in this power-on command is extracted and stored in the memory 3 in S2.

[0014] In S3, the additional information is transferred to the SP (system power control section 7), and in S5, it is stored in the memory. S4 is
The remote power-on control unit 1 notifies the system power supply control (SP) 7 of a power-on instruction. In S6, it is determined whether or not there is an instruction to turn on the power. Here, the answer is YES, and since there was a power-on instruction from the remote power-on control unit (RPCU) 1, the system power control unit 7 powers on the system (CPU 9, etc.) in S7.

At S8, IMPL (initial microprogram loading) of the CPU 9 is performed. S9 is C
PU9 IPL (Initial program loading)
I do. In S10, the CPU 9 reads additional information from the memory 8 of the SP (system power control unit 7).

[0016] In S11, the CPU 9, according to the additional information,
Perform processing. For example, loading a test program, loading a diagnostic program, etc. S12 ends a series of processes instructed by the additional information,
Since the CPU 9 has become operational, the CPU 9 notifies the remote power-on control unit 1 via the communication processor 10.

In S13, the remote power-on control section 1 receives the notification in S12, switches the bus control switch 6, and connects the line and the communication processor 10. This allows communication processor 1
0 directly sends and receives data to and from the other party's device via the line. In S14, the CPU 9 communicates, for example, the test results to the other party's device via a line.

As described above, when the remote power-on control unit 1 detects a power-on command, it captures additional information in conjunction with this power-on instruction and stores it in the memory 3.
This is notified to the system power control section 7 and stored in the memory 8, and a power-on instruction is notified to turn on the power of the system. In response to power-on, IMPL and I are sent to CPU9.
After performing the PL, additional information is fetched from the memory 8 in the system power supply control unit 7, processing according to this additional information (for example, loading of a diagnostic program) is performed, and when the processing is completed, the remote power-on control unit 1 The bus control switch 6 is switched to connect the line, and data is then exchanged directly between the line and the communication processor 10. For example, the results of diagnosis by the diagnostic program are sent to remote maintenance via the line. Transfer to a center, etc. In this way, by temporarily storing the additional information added to the power-on command in the memory, and then retrieving this additional information from the memory after the CPU 9 has started up and performing processing accordingly, remote diagnosis/remote maintenance can be performed. Using this function, a remote maintenance center can obtain the results via line.

Next, using FIG. 3, S1 to S1 in FIG.
A detailed description will be given of the operation when installing a program from a remote maintenance center or the like with the CPU 9 started up by processing such as 4 and connected to the line by switching the bus control switch 6. In FIG. 3, in S21, the CPU 9 receives installation information from a remote maintenance center or the like via the line, the bus control switch 6 of the remote power-on control unit 1, and the communication processor (CP) 10.

[0020] In S22, the installation information received in S21 is temporarily embedded (stored) in a DASD (hard disk device). In S23, the CPU 9 performs an installation process, that is, installs the installation information (system information and user information tailored to the user's specific specifications) embedded in the DASD in S22 (incorporates the program into the system with relationships, and makes it ready for use). do)
Perform processing.

[0021] In S24, the installation process is performed in S23, and the system is activated and starts operation. As described above, various programs can be installed remotely by notifying the installation information to the CPU 9 remotely via a line, storing this information in the storage device, and incorporating it into the system based on this information. It becomes possible. FIG. 4 shows the command of the present invention (
An example of a power-on command) is shown below. As shown in the figure, this power-on command starts with a code that instructs to turn on the power, followed by additional information such as specifying the device to be IMPLed/IPLed, IPLing the OS, and IPLing the test program (diagnosis program). , and other information necessary for diagnosis and maintenance. When the remote power-on control unit 1 in (a) of FIG. 1 detects that the command received from the line is a power-on instruction, it captures the additional information added at the same time, and reads the additional information as shown in FIG.
Processing from S3 onward is performed.

[0022]

[Effects of the Invention] As explained above, according to the present invention,
The command includes not only a power-on instruction but also additional information, which is notified to the remote power control unit 1 via the line and stored in the internal memory, and after the power is turned on and started up, the CPU 9 receives this additional information. Since the system is configured to lead the system and perform processing according to the command (for example, loading a diagnostic program), these processing can be performed using the remote power-on, remote maintenance/diagnosis function, and unattended installation function. It can be performed.
