Installing an adapter
Adapter considerations
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.
•
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 bus 1. The
system scans PCI slots 1 through 5 to assign system resources; then, if you have
not changed the boot precedence from the default, the system starts (boots) the
PCI devices in the following order: PCI slots 1 and 2, system board SCSI
devices, and then PCI slots 3 through 5.
Note:
To change the boot precedence for PCI devices, start the
Configuration/Setup Utility program, and select Start Options from the
main menu. Refer to the User’s Reference on the IBM Netfinity
Documentation CD for details on using the Configuration/Setup Utility
program.
