Adapter considerations
Before you continue with the adapter-installation procedure:
v
Review 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 the adapter, follow the instructions that
come with the adapter documentation.
v
Slots 3 through 6 support 5.0 V and universal PCI adapters.
Note:
A Universal PCI adapter supports both 3.3 V and 5.0 V operation.
v
Slots 1 and 2 support 3.3 V and universal PCI adapters only.
v
The 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.
v
The system scans PCI slots 1 through 6 to assign system resources; then the
system starts (boots) the PCI devices in the following order: processor board
devices, slots 1 and 2, and then slots 3 through 6.
v
The performance of the PCI adapters depends on the types of adapters in the
system.
v
If you install a RAID adapter, follow the instructions in the RAID adapter
documentation for configuring the adapter.
v
If you install a RAID adapter that comes with a backup battery pack, you must
enable the backup battery pack before you can use the RAID adapter.
