ATTO Technology Celerity FC-42XS Troubleshooting Manual page 5

The firmware and driver may not be at compatible revision levels. The drivers are
updated more frequently than the firmware, therefore the revision levels are
seldom the same. There may be an occasion where the latest driver also
requires a firmware update. Verify from the web site that the latest firmware and
driver version are being used. The firmware version can be viewed when the
host adapter is detected during the computer's BIOS scan. The driver version
can be verified from within the Device Manager.
The Celerity host adapter is detected by the operating system, it detects some of
the connected devices on some or all Fibre ports, but does not detect all of the
connected devices.
Verify the Fibre devices are all powered on.
Check cable integrity. Check the cables for solid connections. Make sure they
snap into place. Inspect cable for kinks or cuts.
Verify the SFP is not damaged and rated for the Data Rate trying to be achieved.
Also, try reseating the SFP. If this does not work, try replacing the SFP with a
new one.
Try connecting one device at a time, adding devices until the problem occurs.
This will help pinpoint the device or cable causing the problem.
Watch the LED indicators on the Fibre card. They should show when you have a
proper link and the connection speed you have negotiated with the device after
startup. Drive lights should also flash at startup as the Fibre port is scanned.
This may give a clue as to the root cause of the issue.
Errors are reported while trying to flash new firmware onto the Celerity host
adapter.
The ATTO Configuration Tool performs validations on the structure of the file. If
it does not pass these validations, the file is rejected. The image file may be
corrupted. Try downloading the image file from the support section of the
website again. If you continue to have problems, contact our Technical Support
Department.
The Celerity host adapter fails its Power On Self Test/Post.
The BIOS driver will perform several checks to verify that the host adapter is
functioning. If the BIOS driver determines that the adapter has non-functioning
hardware it will not complete the initialization of the OS driver. If the BIOS driver
determines that the FW on the adapter is not functioning, then it will complete the
initialization in degraded mode. Under Windows, degraded mode will not
perform I/O but it will allow the end user to flash the adapter with working FW.
The POST failure will be recorded in the Windows Event Log. Try to re-flash the
