The following illustration shows the location of the Active™ PCI adapter expansion
slots on the system board.
Note: Active PCI slots are also called hot-plug PCI slots.

The PCI bus configuration follows:
• Hot-plug, 32-bit PCI slot 1 (on PCI bus A, 33 MHz)
• Hot-plug, 64-bit PCI slots 2 through 4 (on PCI bus B, 66 MHz)
• Hot-plug, 64-bit PCI slots 5 through 6 (on PCI bus C, 33 MHz)
• Power-on lights for Active PCI slots
• Internal attention lights for Active PCI slots
• External attention lights for Active PCI slots
This section gives the procedure for installing a hot-plug PCI adapter. If your
operating system supports hot-plug PCI adapters, you can replace a failing hot-plug
PCI adapter with a new adapter of the same type without turning off power to the
server. If your operating system and adapter also support the hot-add feature, you
can install a new adapter without turning off the power to the server.
Before you begin:
• Review the information in "Before you begin" on page 39 and "Working inside
the server with the power on" on page 40.
• Read the documentation that comes with your adapter for any special
requirements or restrictions.
• Read the documentation that comes with your operating system.
Attention: Do not remove a hot-plug PCI adapter before performing the operating-
system-defined procedure for disabling the Active PCI (hot-plug) slot that contains
the adapter. Doing so might cause your system to lock up. Refer to your operating-
system documentation.
