Typical Insertion and Extraction Processes

Typical Insertion and Extraction Processes

Many of the steps in the insertion and extraction processes are automated by software. After the operator installs a board, it automatically advances to P1. The hardware connection process proceeds automatically and asserts the ENUM# signal to initiate the software connection process. The host responds to the bussed ENUM# signal by reading the Hot Swap Control Status Register of each board to find out which one is signaling an insertion or extraction (INS or EXT bit asserted). Upon detecting an insertion, the Host responds by adding software drivers to support the newly inserted board.

Extraction is initiated when the operator opens the board ejector handle, which activates a mechanical switch to assert ENUM#. The hot plug system driver senses ENUM# and notifies software that board activity must be quiesced and that software device drivers should be unloaded. The application that is using the board is informed that the resource is no longer available. When the board is ready for extraction, software informs the operator by illuminating the blue LED. After extraction, all system resources previously assigned to that board are made available for other uses.

Device Drivers

In order to take full advantage of the high availability functions of the CPX8216, and to support hot swap, board device drivers need to be enhanced. Drivers need to cease all activity when the device is about to be hot swapped, and they need to support initialization of the device without support from the device firmware or BIOS.

Further, high availability device drivers need to be able to enter a standby mode while bus control is being passed from one CPU to another. They also provide diagnostic interfaces for run time fault detection and for pre- initialization testing of newly inserted boards.
