PCI Hot Plug Technology
PCI Hot Plug System
A PCI Hot Plug enabled system requires that the appropriate system hardware,
operating system, and device driver support all be enabled. An existing adapter
board should be hot-plug capable as long as it complies with the established
PCI specifications and has hot-plug device driver support. If any of the three
required components are not enabled, the system is still fully functional,
though not hot-plug capable.
PCI Hot Plug Application
The PCI Hot Plug application is the control panel of the PCI Hot Plug
architecture. It allows control of the PCI Hot Plug slots while enabling
configuration of the hot-plug options. Through the PCI Hot Plug application,
you can indicate that you want to replace a board in the hot-pluggable slot or
configure a board that you have already added to the system. This software
also allows you to enable or disable specific slots in the system, and it is
responsible for reporting the status of all boards in the system, especially those
in a degraded state.
PCI Hot Plug Operations
PCI Hot Plug technology provides the ability to remove and replace, upgrade,
and add PCI expansion boards without powering down the server. Any PCI
board can be placed in a PCI Hot Plug slot. PCI Hot Plug device drivers and
operating system support, however, are required to enable the PCI Hot Plug
feature.
PCI Hot Plug Button
The PCI Hot Plug button provides PCI Hot Plug access directly at each PCI
slot and PCI Hot Plug control of each slot without requiring the use of
PCI Hot Plug utility software. The PCI Hot Plug button allows you to cancel
an action by pressing the button again within five seconds.
