Patent ID: 7725753

Claim:
An identification apparatus for a backup-type power supply system which includes N+1 power supply devices connecting to a power integration back panel which integrates power output, the power supply devices including a real power supply device and a dummy power supply device, the identification apparatus comprising: a real identification signal generation means for generating a ground potential identification signal and a dummy signal identification generation means for generating a floating potential identification signal to indicate whether a malfunction refers to a real power supply device or a dummy power supply device, wherein the real signal identification means is located on a connection port of the real power supply device and the dummy signal identification means is located on a connection port of the dummy power supply device, which dummy power supply device does not supply power, but has a specification, dimension and profile of a real power supply device, including a cooling air fan, and wherein power for the dummy power supply device comes from the real power supply device; and a signal detecting means for receiving the real identification signal and the dummy identification signal, which signal detection means is configured to transmit the real identification signal and the dummy identification signal to determine installation and coupling conditions of both the real power supply device and the dummy power supply device ; and a display means for indicating the coupling and installation conditions of the real power supply device and the dummy power supply device.
