Adapter considerations

IBM® Netfinity® 3500 M20 Installation Guide
You can install up to five peripheral component interconnect (PCI) adapters in the PCI
slots on the system board.
Your server comes with an integrated video controller, which is a component on the
system board. When you install a video adapter, the server BIOS automatically
disables the integrated video controller.
The following illustration shows the location of the 33 MHz PCI expansion slots on
the system board.
Note: The illustrations in this document might differ slightly from your hardware.
PCI slot 1
32-bit
33 MHz (J29)
PCI slot 2
32-bit
33 MHz (J31)
PCI slot 3
64-bit
33 MHz (J35)
PCI slot 4
64-bit
33 MHz (J39)
PCI slot 5
64-bit
33 MHz (J40)
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.
• 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.
