HP ProLiant DL740 Server - Manual (Page 27)

Server Features
PCI-X Technology
PCI-X technology leverages the wide acceptance of the PCI bus and provides an
evolutionary I/O upgrade to conventional PCI. PCI-X technology enhances the PCI
protocol and frequency to meet bandwidth needs of enterprise computing systems.
PCI-X provides backward compatibility with the PCI bus at both the expansion board
and system level.
Expansion Slots
The server has six 64-bit PCI-X expansion slots operating at 100 MHz:
• Slots 1 and 2 (PCI bus 7) support PCI-X expansion boards at 100 MHz; it is
keyed for 3.3v signaling.
• Slots 3 and 4 (PCI bus 11) support PCI-X expansion boards at 100 MHz; it is
keyed for 3.3v signaling.
• Bus 5 and 6 (PCI bus 3) support PCI-X expansion boards at 100 MHz; it is keyed
for 3.3v signaling.
NOTE: The operating system detects PCI devices in the following slot order: 5-6-1-2-3-4.
PCI Hot Plug
PCI Hot Plug provides the ability to remove, replace, upgrade, and add PCI/PCI-X
expansion boards without powering down the server. PCI and PCI-X boards can be
placed in a PCI Hot Plug slot. PCI Hot Plug device drivers and operating system
support are required to enable PCI Hot Plug.
A PCI Hot Plug button is located above each PCI/PCI-X slot, providing PCI Hot Plug
control directly at the server without the use of the PCI Hot Plug utility software.
For more information about PCI Hot Plug, refer to the server documentation CD.
