General Handling and Failure Reporting Guidelines

 Verify the problem on other cards or channels, if possible.
 Use a spare card and see if that fixes the problem.
 Note card part number and serial number, as well as PO number, if possible.
 Confirm whether the problem appeared during installation or well after successful installation, i.e. did
the problem occur with no changes to a previously working system?
 Log a diagnostics file, if relevant, and email it to the factory. Diagnostics files include all optical
measurements, temperature, voltage levels, video syncs, and errors detected. Ensure the log file is
configured properly per the software user's manual. (The various log fields may be enabled/disabled
and the logging frequency may be changed from the one second default.)

7.4.1 Focal Service and Support

It is recommended that damaged cards or cards/systems that the fault cannot be found in using the above
guide be returned to Focal or local supplier.
 Request a RMA # from Focal (Tel: 1-902-468-2263) and complete a return product form.
 Provide key information, such as a description of the problem, the part number of the board, how long
the board has been in service, any attempted fixes, and the urgency for repair.
Ensure packaging is secure and ESD safe.

LED STATUS – NORMAL OPERATION CONDITION
Green LED on LINK, FO-RX and STAT on both remote and console modules.
Green RJ-45 port LED: ON = valid link, FLASHING = data activity
Yellow RJ-45 port LED: ON = full duplex link, FLASHING = data collisions
Green Panel LED ("T"): ON = data received from backplane (10 Mbps EIB only)
Red Panel LED ("R"): ON = data sent to backplane (10 Mbps EIB only)
Two LEDs for each channel indicate the presence of a signal transmitted or received:
Green LED ("T"): ON = data being transmitted out of card front panel to external equipment.
Red LED ("R"): ON = data being received into card front panel from external equipment.
Non-digital i/o cards (e.g. AIB-MS900) or blank sockets force both LEDs on.
Two LEDs for each channel indicate the presence of a signal transmitted or received:
Green LED ("T"): ON = data being transmitted out of i/o box to external equipment.
Red LED ("R"): ON = data being received into i/o box from external equipment.
Green LEDs on PSU front panel indicate corresponding output voltage levels are OK.
Flickering or dim LEDs indicates power problems on the rails.
CONDITION
Normal operating condition
(Valid uplink/downlink established)
Insufficient power budget
Insufficient optical power in one
direction
Problem with optics between
remote and console modules
Model 903-HD User's Guide – FMB-X-2.5
POTENTIAL SOLUTION
OK
Verify optical power budget with VOAT.
Verify attenuation, optical cable and connections.
Re-establish synchronization (unplug/plug the fiber optic cable).
Replace FMB that has the red LED if received optical power is OK.
Check FMB DIP switch settings per Manual.
Bad connector: clean all optical connections.
Bad fiber: bypass fiber sections with jumpers.
