Issue
- I/O modules that cannot be successfully commissioned
-
Is there a procedure to test these or any resets or checks to do before sending the IOU back for repairs?
Environment
- CX96xx
- I/O Module
Cause
Unable to commission I/O module.
Resolution
FLASHING STATUS LIGHT
This indicates that the Neuron chip in the module has undergone a partial commissioning and that it has calculated an invalid checksum in its flash chip. This could happen due to communications problems on the IOU bus, either during module commissioning or during a NetController reload (which also de-commissions and re-commissions the modules).
If you are experiencing this problem, do not return the modules to the Repair department. We have added a routine in the NetController to automatically detect and correct this condition. You can download the new NetController flash file and upgrade your NetController in the field. This will automatically correct any IOU modules that have this condition.
To avoid this issue, you should also verify that your controllers and IOU modules are installed per the installation instructions, paying careful attention to bus topology, bus terminations, network cable, and grounding.
Please note when adding multiple IOU modules that exhibit the behavior described above, to add and commission the modules onto the system one at a time.
SOLID STATUS LIGHT
This indicates that the IOU module application flash is not present in the module. This could happen either due to the conditions described above or by a failure during the flash upgrade process.
These modules can be corrected in the field using one of the manual procedures described below:
If the module was already commissioned on the NetController
If the NetController has the module information in its memory, you should be able to flash the IOU firmware by editing the IOU object and selecting the “Update IOU” button. Then select the correct flash file for that module.
If the module will not upgrade
- Connect the faulty module to a CX9xxx.
- With CyberStation online, create an IOU module. Specify IOU number but not module ID. Save and close the editor disregarding the error message.
- Set CyberStation offline. Edit the IOU module object inserting the module ID. Save and close the editor. Set CyberStation back online.
- Open the IOU module object, re-insert the module ID, select the Uprev button, and select a .upd file.
- When the uprev completes, commission the module.
TAC product development has made a correction to this issue Click Here in firmware version 1.530023.
You should also read Technical Bulletin #1041 to make sure that you are using the correct IOU file.
