The PCI Hot Plug button and the PCI Hot Plug utility allow you to power on or power off
a hot-pluggable I/O expansion board slot. However, the PCI Hot Plug Button allows direct
access at each hot-pluggable expansion slot.

PCI Hot Plug software support for each operating system is available online. For more
information, see the "PCI Hot Plug Important Facts" section in the online PCI Hot Plug
Administration Guide on the Server Documentation CD.

CAUTION: Do not attempt a PCI Hot Plug procedure if your operating system does not provide
PCI Hot Plug support, or if you do not have the appropriate device drivers installed. Failure to
take these precautions causes system shutdown and risks data integrity.
CAUTION: To avoid critical errors, do not open the slot release lever if the green power LED is
on or blinking. Use the PCI Hot Plug button or the software application to turn off power to
the slot.
