optional PCI-X riser-card assembly, slots 1 and 2 are non-hot-plug, 64-bit,
133-MHz PCI-X slots, which support Integrated xSeries
single-width adapters.
v The system scans devices in the following order, if you have not changed the
default boot precedence: integrated Ethernet controllers, integrated SAS
controller, and then PCI slots 1, 2, 3, and 4.

To install an adapter, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 9.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables.
Attention: In a dc power environment, only trained service personnel other
than IBM service technicians are authorized to connect or disconnect power to
the dc power supply. See the documentation that comes with each dc power
supply.
3. Remove the server cover.
4. Determine which expansion slot you will use for the adapter. If you are installing
an adapter in PCI slot 1 or 2, remove the PCI riser-card assembly.
