A method of automatic identification of PCIe configuration of a server and preventing operation if each slimline connector connected with a PCIe device is found connected to an incorrect slot of a mother board utilizes a combination of first and second signals of two null interfaces of the first connector as that ID signal and a combination of third and fourth signals of the two interfaces of a second connector as that ID signal. The CPLD receiving the ID signals detects whether the first and second slimline connectors are in their specified and correct slots. Powering on of computer is not permitted if incorrect connection is found, and a warning prompt is generated. A PCIe channel width for each slimline is automatically configured if no incorrect connection is found. A server applying the method is also disclosed.
