New Boards Cannot Be Registered on an NE40E Due to a CF Card Fault

Publication Date:  2018-10-09 Views:  93 Downloads:  0
Issue Description
A hardware fault occurs on the 10GE board in slot 8 on an NE40E at a customer site. During routine spare parts replacement, the new board cannot be registered.
Handling Process
1. No spare CF card is available on the site. Therefore, the faulty CF card is formatted, and the version file is uploaded again.

2. After a master/slave switchover is performed again, hot swap the new board. The board can be registered, and the problem is resolved.

Root Cause
1. After the spare board is inserted into another slot, the problem persists. Therefore, the problem is not caused by the slot on the NE40E.

2. After the spare board is inserted into a slot on an NE40E of the same model, the board can be registered. Therefore, the problem is not caused by the spare part.

3. Check other normal information such as the power supply. No exception is found.

4. Perform a master/slave main control board switchover. After the spare board is inserted, the board can be registered. Therefore, a main control board fault causes the board registration failure.

5. Run the dir command. Many invalid files are found in the CF card of the original main control board, and the size of the file is 0. It is suspected that a hardware fault of the CF card causes the board registration failure.

Suggestions
When a board is installed, the version file needs to be read from the CF card of the main control board. If the CF card is faulty, the new board cannot be installed.
