5.5 PICMG 2.1 Hot Swap Support
The cPCI-6760D Hot-Swap capability allows non-system slot
boards to be added or removed while the system is powered up.
Individual clocks for each slot and access to the ENUM# signal on
the backplane are compatible to PICMG 2.1 Hot Swap
Specification. While hot swap of non-system boards is supported,
the cPCI-6760D itself cannot be inserted to or removed from a
powered system.
A signal (ENUM#) is provided to notify the cPCI-6760D that either
a board has just been inserted or is about to be extracted. This
signal drives an interrupt (IRQ9 or IRQ3, according to hardware
configuration) to inform the cPCI-6760D that the existence of a
peripheral board has changed. The cPCI-6760D then performs
any necessary maintenance such as installing a device driver
upon board insertion, or quiescing a device driver and the board,
prior to the board’s extraction. The CompactPCI Hot-Plug System
Driver manages the ENUM# sensoring.
Hot Swap Software builds on the PCI Hot-Plug architecture. The
Hot-Plug Service, Hot-Plug System Driver, and the Device Drivers
are common elements with the Hot-Plug architecture. The Device
Drivers for Hot-Swap boards must be Hot-Plug capable. The Hot-
Plug Service provides for the Dynamic Configuration of the system
as the resources are added or removed. The PCI Hot-Plug
Specification defines these services.
To support Hot Swap capability, the peripheral board shall be fully
compliant with PICMG 2.0 R3.0 and PICMG 2.1 R2.0. The board’s
insertion and extraction processes are summarized as follows.
