PCI-X Hot Plug and Non-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 replace, add, and upgrade 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)
For information about specific operating systems with PCI-X Hot Plug support, refer to the
operating system support matrix available at

WARNING: To reduce the risk of personal injury from hazardous energy or damage to
the equipment when working on energized servers:
• Remove all watches, rings, and any other loose-fitting jewelry.
• Avoid the use of conductive tools that could bridge live parts.
IMPORTANT: If any of the three required components are not hot-plug aware, the system is fully
functional but is not PCI-X Hot Plug-capable.
