DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component insertion notifying method for transferring a mounting signal to a monitoring unit of a component already mounted after the mounting of the component is ensured.

In recent years, telephone exchanges and the like have been operated for 24 hours. Such a device has a device configuration that allows replacement of components while the device is in operation.
The replacement is performed by inserting the component into the connector, but the pins of the component and the connector are not always completely in contact with each other.

[0003] Therefore, in a device that adopts a configuration for notifying a mounted signal to a mounted component in mounting a mounted component, an erroneous mounting signal may be notified in some cases. Since such notification may cause the system to go down, the notification of the mounting signal must be complete.

2. Description of the Related Art In a conventional 24-hour operation device, when components are exchanged, when a component to be mounted is mounted on a printed circuit board, for example, a mounting signal is transmitted from the component to the printed circuit board. Or after transferring to other components on other printed circuit boards and receiving this mounting signal transfer,
The device is operated by accessing the mounted components from the already mounted components.

[0005]

The transfer of the mounting signal as described above is usually performed through a connector, and the mounting signal is transferred to the already mounted component even though the mounting is not completely completed. Sometimes.

In such a case, when the already mounted component that has received the mounting signal accesses the mounted component,
If the contact between the mounted component and the connector is incomplete,
Wrong data will be taken from the already mounted components. If the data has a significant effect on the operation of the device, the device may be rendered inoperable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above technical problems, and has a structure capable of preventing a device from malfunctioning by transferring a mounting signal to a monitoring unit after a component is completely mounted. Its purpose is to provide a product insertion notification method.
