Pci Hot-Plug I/O Expansion Boards - Compaq ProLiant DL760 Service Overview

Compaq ProLiant DL760

PCI Hot-Plug I/O Expansion Boards

The ProLiant DL760 server supports PCI Hot Plug. PCI Hot Plug and the server's operating
system work together to allow the following hot-plug actions:
•
Hot replacement of expansion boards–This feature allows you to replace a failed
expansion board with an identical expansion board without powering down the server.
•
Hot addition of expansion boards–This feature allows you to install new PCI/PCI-X
expansion boards in previously empty slots without powering down the server under
some operating systems.
•
Hot upgrade of expansion boards–This feature allows you to replace an expansion
board with a different expansion board without powering down the server.
PCI Hot Plug is backward compatible, although system components fit into one of two
categories; hot-plug aware or non-hot-plug aware. The following three components are required
in the server for complete PCI Hot Plug capability:
•
PCI Hot Plug system hardware (available in this server)
•
Operating system with PCI Hot Plug support (currently Microsoft Windows 2000,
Microsoft Windows NT, Novell NetWare, and SCO UNIX – support level varies)
•
PCI Hot Plug device drivers (available from operating system vendors, Compaq
SmartStart CD, and some individual hardware vendors)
IMPORTANT: If any of the three required components are not hot-plug aware, the system is
fully functional, but not PCI Hot Plug-capable. For further information about PCI Hot Plug
consult the ProLiant DL760 Servers User Guide First Edition (March 2001) Part Number
173774-001
IMPORTANT: Hot addition is not supported under Windows NT 4.0. Empty slots are powered
up at boot and opening the slot release lever will cause the slot to be powered off. If you add a
board in this manner, you will not be able to power up the slot. Windows NT 4.0 does, however,
support hot replacement of identical I/O expansion boards. See the Compaq QuickSpecs for the
Compaq ProLiant DL760 servers at www.compaq.com for a list of supported I/O expansion
boards.
