PCI Hot Plug Technology
This chapter includes a brief discussion of PCI Hot Plug technology. For more
information, see the online PCI Hot Plug Administration Guide and the PCI
Hot Plug animation on the Documentation CD.
The ProLiant 6400R server supports PCI Hot Plug. PCI Hot Plug and the
server operating system work together to allow the following hot-plug actions:
■ Hot replacement of adapters – Replace a failed adapter with an
identical adapter without powering down the server.
■ Hot addition of adapters – Install new PCI expansion boards in
previously empty slots without powering down the server.
■ Hot upgrade of adapters – Replace an adapter with a different adapter
without powering down the server.
PCI Hot Plug is backward compatible, though system components fit into one
of two categories: hot-plug aware or non-hot-plug aware. The following 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 Windows NT,
NetWare, and SCO UNIX)
■ PCI Hot Plug device drivers (available from operating system vendors,
the Compaq SmartStart and Support Software CD, and some individual
hardware vendors).
IMPORTANT: If any of the three required components are not hot-plug aware, the system
is fully functional, though not PCI Hot Plug capable.
