To reinstall the support-bracket assembly, reverse these steps. Working with adapters Your server comes with adapter connectors, called slots. The AGP video adapter is installed in the AGP slot. 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. AGP slot PCI slot 1 PCI slot 2 PCI slot 3 PCI slot 4 PCI slot 5 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 Chapter 5.

To reinstall the support-bracket assembly, reverse these steps.
Working with adapters
Your server comes with adapter connectors, called
slots
. The AGP video adapter is
installed in the AGP slot. 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

PCI slot 2
PCI slot 3
