Methods for determining whether the standby board and the board in use are of the same type from board barcodes

3

If the first six digits in the barcode of the boards are the same, and the first six digits in the 03+ barcode queried on PDM system are the same, you can replace the board in use with a spare board.
You can also check the board type information on the front panel of the board. If the types are the same, you can replace the standby board with the board in use.

Methods used to determine the board wavelengths according to the barcode of the wavelength conversion board
The first five digits in the feature code of a fixed-wavelength OTU board indicate the wavelength. For example, 19300 indicates 193.00 THz.

Methods for identifying board wavelengths according to barcodes of the wavelength conversion boards
For the feature code of a fixed-wavelength OTU board, the first 1 to 5 digits represents the wavelength. For example, 19300 indicates that the wavelength of a board is 193.00 THz.

Method used to determine whether a board supports tunable wavelengths
On the NMS, query the manufacturer information of the desired board. If "Tunable" is included in the information, the board supports tunable wavelengths.

Whether the hardware version of the standby SCC board must be the same as that of the active SCC board during the replacement of the standby SCC board
During the replacement of the standby SCC board, the hardware versions of the active and standby SCC boards can be different, but the spare and to-be-replaced SCC boards must be substitutable. In addition, the SCC boards in the subrack housing the to-be-replaced SCC board must be the same type. That is, the active and standby SCC boards must be the same after the replacement.

Whether the software version of the standby SCC board must be the same as that of the active SCC board during the replacement of the standby SCC board
There is no version requirement for the standby SCC board during the replacement of the standby SCC board. This is because that the software needs to be erased using DIP switches before a spare SCC board is used to replace the standby SCC board. After the spare SCC board is inserted to a subrack, the board software of the standby SCC board will be automatically synchronized with the active SCC board.
