Note: All PCI-compliant and PCI-X-compliant systems automatically detect 32-Bit
or 64-Bit adapters and set the appropriate bus speed (for example, 66 MHz
or 133 MHz).
If you still have a system configuration problem, refer to the documentation that
comes with your server, or contact your IBM technical-support representative to
determine if your system board requires special configuration.
Fibre Channel problems
To determine if your installation problem is caused by an attached Fibre Channel
device, perform the following tasks:
v Verify that all of the Fibre Channel devices were turned on before you turned on
the server.
v Ensure that all cables are connected properly.
v Verify that you configured your RAID storage subsystems using the utilities
provided by the manufacturer.
v If your Fibre Channel switch supports zoning, make sure that your peripheral
device is configured to the same switch zone as the FC 4Gbps PCI-X Adapter.
For more information, refer to your Fibre Channel switch documentation.
In certain cases where the target device may not be able to auto-negotiate the
Fibre-channel data rate properly, make sure that data rate setting on the FC 4Gbps
PCI-X HBA matches the target device. For example, if the target device is operating
at 2Gbps, set the FC 4Gbps PCI-X HBA data rate to 2Gbps.
