Are all of the circuit cards installed securely in the system?
■
Are all of the cables securely connected to the correct connectors? Be sure
that the FC cables that attach from the HBA connectors to the device are
connected correctly. For example, the optical transmit connector on the HBA
must be connected to the optical receive connector on the device. Some
connectors require a firm push to ensure proper seating. An easy way to check
for correct seating is to switch the connectors on either the HBA or the device,
then reboot the system.
■
Is the HBA installed correctly in the PCI slot? Is it seated firmly in the slot?
■
Check for interference due to nonstandard PCI connectors.

setting the data rate.

Are all external peripherals properly powered up? Refer to
information about displaying attached devices.
