Installing Hardware Options, Hot-Plug
PCI-X Hot Plug I/O Expansion Boards
The ProLiant DL740 server supports PCI-X Hot Plug. PCI-X Hot Plug and the
operating system of the server work together to allow the following hot-plug actions:
Hot-replace—Allows you to replace a failed expansion board with an identical
expansion board without powering down the server.
Hot-add—Under some operating systems, allows you to install new PCI-X
expansion boards in previously empty slots without powering down the server.
Hot-upgrade—Allows you to replace an expansion board 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.
PCI-X Hot Plug is backward compatible, although system components fit into one of
two categories: hot-plug aware or non-hot-plug aware. The server must have all of
the following to be PCI-X Hot Plug-capable:
PCI-X Hot Plug system hardware (available in this server)
PCI-X Hot Plug device drivers (installed from the SmartStart CD)
An operating system that supports PCI-X Hot Plug technology (support
levels vary)
