Abstract

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.

Dependent claims

A method of automatic identification of PCIe configuration of a server, the server in a server system comprises a mother board, a first connector, a second connector, and a complex programming logic device (CPLD);

the method comprises:
defining a combination of a first signal and a second signal received by two interfaces of the first connector as an ID signal of a first slimline, and a combination of a third signal and a fourth signal of two interfaces received by the second connector as an ID signal of a second slimline;
obtaining the ID signals of the first slimline and the second slimline by the CPLD according to the first to fourth signals, and detecting whether the first slimline and the second slimline are correctly with specified slots of the mother board respectively;
forbidding the server system to being powered on when any one of the first slimline and the second slimline is connected with an incorrect slot and generating a warning prompt;
and
normally starting the server system and automatically configuring a PCIe channel width to each slimline when both of the first slimline and the second slimline are connected with the specified slots respectively.
