Device hot plug system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a hot-plug engine that is configured, in response to a hot-plug event with a connector, to:
• enter a reset state;
• monitor, while in the reset state, a reference clock;
• determine, while in the reset state, that the reference clock has been stable for a predetermined time period;
• exit, in response to determining that the reference clock has been stable for the predetermined time period, the reset state;
• and
• provide, in response to exiting the reset state, a de-assertion signal on a reset pin included on the connector.

A method for hot-plugging a device, comprising:

• entering, by a hot-plug device in response to being hot-plugged to a connector, a device reset state;
• monitoring, by the hot-plug device while in the device reset state, a reference clock;
• determining, by the hot-plug device while in the device reset state, that the reference clock has been stable for a predetermined time period;
• exiting, by the hot-plug device in response to determining that the reference clock has been stable for the predetermined time period, the reset state;
• and
• providing, by the hot-plug device in response to exiting the reset state, a de-assertion signal on a reset pin included on the connector.
