Adapter considerations
Before you install adapters, 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 expansion slots.
• You can install a 32-bit 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.
• 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.
• The server has two PCI buses. PCI slots 1 and 2 are on PCI bus A, and PCI slots
3, 4, and 5 are on PCI bus B.
Note: PCI bus A is sometimes referred to as bus 0; PCI bus B is sometimes
referred to as bus 1.
The system scans PCI slots 1 through 5 to assign system resources; then, the
system starts (boots) the PCI devices in the following order: PCI slots 1 and 2,
system board SCSI devices, and then PCI slots 3 through 5.
• If you plan to use the Wake on LAN (WOL) function in the server, you must
install a Wake on LAN-enabled network interface card (NIC adapter) in PCI slot
1, and install the Wake on LAN cable that comes with the Wake on LAN adapter
to connect this adapter to the system board. You must use a Wake on LAN-
enabled adapter as identified in the xSeries 220 ServerProven list at
http://www.ibm.com/pc/compat/. Only PCI slot 1 supports a Wake on LAN-
enabled adapter. For additional information on the Wake on LAN function,
adapter, and cables, refer to the documentation that comes with the Wake on
LAN adapter.
• If you plan to use the optional system-management adapter function in the
server, you must install the optional system-management adapter in PCI slot 2.
Only PCI slot 2 supports the optional system-management adapter. For
additional information on the optional system-management adapter, refer to the
documentation that comes with the adapter.
