2.5 CompactPCI Hot Swap

CompactPCI is the specification made by applying the existing specification of PCI Local Bus for

general PC to the industrial PC. The algorithms such as bus protocol are same as those of the

existing PCI, except for the electrical features and the mechanical features. Hot Swap is one of

the functions that reinforce the industrial aspect of CompactPCI. The function enables you to

delete/insert the CompactPCI board while power is connected to the system.

CompactPCI hot swap capability supports the software aspect of the Hot Swap Function. The

control register is in the Configuration Space Header. In SB4002A, the control register is in

50h~53h.

SB4002A follows the CompactPCI Hot Swap Specification 1.0. The following table shows the

registers contained in the Configuration Space Header.
