Working with adapters
Your server comes with adapter connectors, called slots. The AGP video adapter is
installed in the AGP slot and some server models come with a SCSI adapter installed
in PCI expansion slot 2. You can install up to five PCI adapters in PCI expansion slots
1 through 5. All PCI expansion slots are 32-bit, 33 MHz slots.
Note: The illustrations in this document might differ slightly from your hardware.
The following illustration shows the location of the PCI expansion slots on the system
and PCI extender boards.
Adapter considerations
Before you install an adapter, 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 switch or jumper settings on your adapter, follow the instructions that
come with the adapter.
• You can install full-length adapters in all five PCI expansion slots.
• 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.
• If you are installing or replacing an adapter that will control your startup (boot)
drive, install the adapter in PCI expansion slot 2.
• PCI expansion slots 1 through 5 are on PCI bus 0.
The system scans the AGP slot and PCI expansion 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 default boot sequence: PCI expansion slots 1
through 5; then, the system board integrated drive electronics (IDE) or SCSI
devices.
Note: To change the startup sequence for PCI devices, start the
Configuration/Setup Utility program, select Start Options from the main
menu, select Startup Sequence; then, select Second device (SCSI) to
designate the adapter boot sequence. See Chapter 4, “Configuring your
