Abstract:
A signal switch apparatus, which is disposed on a motherboard, wherein the motherboard comprises an interrupt controller, a first peripheral component interface, a first PCI slot, and a second PCI slot, comprising:a signal switch component, which is connected to the interrupt controller and the first PCI slot and the second PCI slot; wherein when a small computer system interface, SCSI, card is inserted into the first PCI slot, an interrupt signal sent by the SCSI card is connected to the interrupt controller through the signal switch component, and when the SCSI card is inserted into the first PCI slot and a redundant array of independent disk, RAID, card is inserted into the second PCI slot, the interrupt signal sent by the SCSI card is connected to the RAID card; wherein the signal switch component comprises: a first pin, which is connected to the first PCI slot and the second PCI slot; a second pin, which is connected to the interrupt controller; a third pin, which is connected to a high level signal; and a switch signal, wherein when the SCSI card is inserted into the first PCI slot and the RAID card is inserted into the second PCI slot, the switch signal is at low level, wherein when the SCSI card is inserted into the first PCI slot, the switch signal is at high level.
