The Previous Chapter

PCI Express includes native support for hot plug implementations. The previous chapter discussed hot plug and hot removal of PCI Express devices. The specification defines a standard usage model for all device and platform form factors that support hot plug capability. The usage model defines, as an example, how push buttons and indicators (LED's) behave, if implemented on the chassis, add-in card or module. The definitions assigned to the indicators and push buttons, described in this chapter, apply to all models of hot plug implementations.
