The following illustration shows the location of the 33 MHz PCI expansion slots on
the system board.

Before you install adapters, review the following:
• Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change the switch or jumper settings on your adapter, follow the instructions
that come with the adapter.
• You can install full-length adapters in all expansion slots.
• You can install a 32-bit adapter in any of the PCI slots, but you might want to
install it in a 32-bit slot and use the 64-bit slots for 64-bit adapters.
• Your server supports 5.0V and universal PCI adapters; it does not support 3.3V
adapters.
• You might require additional power supplies if adapters are added that have
electrical current requirements that exceed the installed power supply
capabilities.
• Your server uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
• PCI slots 1 and 2 are on PCI bus A and PCI slots 3, 4, and 5 are on PCI bus B.
PCI bus A is often referred to as bus 0; PCI bus B is often referred to as
Note:
bus 1.
