PCI-X Hot Plug Technology
The server supports PCI-X Hot Plug technology.
PCI-X Hot Plug Features
PCI-X Hot Plug and the server’s operating system work together to enable the
following hot-plug operations:
• Hot replacement of expansion boards
A failed expansion board can be replaced with an identical expansion board
without powering down the server.
• Hot addition of expansion boards
New PCI expansion boards can be installed in previously empty slots without
powering down the server.
• Hot upgrade of expansion boards
An expansion board can be replaced with a different expansion board without
powering down the server.
PCI-X Hot Plug features enable you to remove, upgrade, and add PCI or PCI-X
expansion boards without powering down the server by either using the PCI Hot Plug
button or the PCI Hot Plug Utility software. Any PCI adapter can be placed in a PCI
Hot Plug slot. However, PCI Hot Plug device drivers and operating system support
are required to enable the PCI Hot Plug feature.
