Troubleshooting
4.1
Problems After Installation
There are three basic types of installation problems that can cause your QLA23xx
HBA to function incorrectly: hardware problems, system configuration problems,
and Fibre Channel problems. The following section provides itemized checklists to
help you determine why your QLA23xx HBA is not functioning.
4.2
Hardware Problem Checklist
■ 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 QLA23xx HBA connectors to the
device are connected correctly. For example, the optical transmit connector
on the QLA23xx 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 QLA23xx HBA or the device, then restart your system. If the BIOS is
enabled, devices attached to the QLA23xx HBA are displayed on the screen.
■ Is the QLA23xx HBA installed correctly in the PCI slot? Is it seated firmly in
the slot?
■ Check for interference due to nonstandard PCI connectors.
■ Is the Fast!UTIL data rate setting correct? See the appropriate Fast!UTIL
section for information about setting the data rate.
■ Are all external peripherals properly powered up? See the appropriate
Fast!UTIL section for information about displaying attached devices.

System Configuration Problem Checklist
All PCI-compliant and PCI-X-compliant systems automatically detect 32-bit or 64-bit
HBAs and set the appropriate bus speed (for example, 33 MHz or 133 MHz). Check
the motherboard for proper configuration (see the appropriate installation section
for more information.
See the documentation supplied with your computer, or contact your computer
dealer to determine if your motherboard requires special configuration.
