8 IBM® xSeries 330: Installation Guide
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 in this chapter. If you need to change
the switch settings or jumper settings on your adapter, follow the instructions
that come with the adapter.
• You can install 32-bit or 64-bit full-length or half-length adapters in the
expansion slots. Full-length adapters are installed in slot 1; half-length adapters
are installed in either slot 1 or 2.
• Your server supports 5.0V and universal PCI adapters; it does not support 3.3V
only adapters.
• Your server uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install PCI adapters that currently do not
support sharing of PCI interrupts.
• PCI slots 1 and 2 and the integrated SCSI controller are on PCI bus B; the system
board and all other integrated devices are on PCI bus A.
Note: PCI bus A = bus 0; PCI bus B = bus 1.
• The system scans PCI slots 1 and 2 to assign system resources. By default, the
system starts (boots) devices in the following order: System SCSI devices, then
PCI devices.
Note: To change the boot precedence, start the Configuration/Setup Utility,
select Start Options from the main menu. Then, select the PCI SCSI
adapter boot option.
Installing an adapter
Complete the following steps to install an adapter:
Attention: When you handle electrostatic discharge (ESD) sensitive devices, take
precautions to avoid damage from static electricity. For details on handling these
devices, refer to “Handling static sensitive devices” on page 4.
1. Review the safety precautions beginning on page v.
2. Turn off the server and peripheral devices.
3. Remove all external cables from the server; then, remove the server from the rack
and remove the cover as shown. For more information on removing the cover,
refer to the User’s Reference on the IBM xSeries Documentation CD.
4. Remove the expansion slot clip that holds the expansion slot cover in place by
sliding it upward and off the frame of the server.
