Claim 0:
1. A detection system for a SlimSAS slot, comprising:
a circuit board, comprising at least one SlimSAS slot and a boundary scan chip;
a detection card, comprising:
a SlimSAS connection interface, comprising two sets of system management bus (SMBus) pins, differential signal receiving pins, differential signal transmitting pins, two sets of clock pins, sideband pins and ground pins;
a HCSL to LVDS module chip, electrically connected the two sets of clock pins;
an inter-integrated circuit (IIC) chip, electrically connected to the SMBus pins;
a controllable power module chip;
a complex programmable logic device (CPLD) chip, electrically connected to the HCSL to LVDS module chip, the controllable power module chip, the HC chip, the sideband pins and the ground pins; and
a joint test action group (JTAG) port, electrically connected to the CPLD chip and the controllable power module chip;

a test access port (TAP) controller, electrically connected to the JTAG port; and
a detecting device, electrically connected to the TAP controller;
wherein the detecting device generates a detection signal, and transmit the detection signal to the TAP controller, the TAP controller converts the detection signal into a second detection signal in JTAG format, transmits the second detection signal in JTAG format to the CPLD chip and the controllable power module chip of the detection card and/or the boundary scan chip of the circuit board, so that a detection is performed on the SMBus pins, the differential signal receiving pins, the differential signal transmitting pins, the clock pins, the sideband pins and the ground pins of the SlimSAS connection interface through the boundary scan chip, the HCSL to LVDS module chip, the HC chip, and the CPLD chip.
