装置。[Scope of Claim for Utility Model Registration] In a switchboard control device that exchanges control information with n switchboards (n is 1 or more), immediately after the switchboard control device performs IPL, the switchboard controller transmits information to each switchboard for all of the switchboards. means for sequentially and repeatedly transmitting corresponding individual response request signals at regular time intervals; means for identifying a response from the switchboard to the response request signal; and determining that the response from the switchboard is the first response. An exchange characterized by comprising means for recognizing that the switch has been powered on, and means for determining that a failure has occurred in the corresponding switch when there is no response to a subsequent response request signal within a certain period of time. Base control device.
