Adapter considerations
Before you continue with the adapter-installation procedure:
• Review the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this section. 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 RAID 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.
Note: Universal PCI adapters support both 3.3 V and 5.0 V operation.
• 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 primary PCI bus A and PCI slots 3, 4, and 5 are on
secondary PCI bus B. The system scans PCI slots 1 through 5 to assign system
resources; then the system starts (boots) the PCI devices in the following order, if
you have not changed the boot precedence from the default: PCI slots 1 and 2,
system board SCSI devices, and then PCI slots 3 through 5.
