<p>An interface system (10) for ensuring connection reliability between a sub-card and a backboard (20) in rack equipment is provided. The interface system (10) comprises: a board in-place detection unit (11) for detecting whether the sub-card is inserted into place correctly when a connection pin set of the sub-card is inserted into a connector on the backboard (20); a chassis detection unit (12) for judging whether the current chassis inserted into by the sub-card is the applicable chassis for the sub-card; and a slot position detection unit (13) for judging whether the current slot position inserted into by the sub-card is the applicable slot position for the sub-card. When the sub-card is inserted into the backboard (20), the interface system (10) not only detects whether the sub-card is correctly installed into place, but also further detects the code of the chassis with the backboard (20) into which the sub-card is inserted and the code of the slot position being inserted, and confirms the present working environment of the sub-card, thus comprehensively detecting the connection status between the sub-card and the backboard (20), and ensuring the reliable connection between the sub-card and the backboard (20). A backboard (20) and a method for ensuring connection reliability between a sub-card and a backboard (20) in rack equipment are also provided.</p> |
