Hello friend!
Before you start the configuration, you need to ensure that:
The NE user has higher operation rights.
All boards are correctly installed.
The ODU power switch on the IDU 905 2E is turned on. The ODU communicates with the IDU properly.
The detailed configuration method is as follows:
Based on the slot layout, the NE automatically configures the logical boards that are required but are not yet configured for certain physical boards.
On the slot to which the board is to be added, right-click and select Add XXX. "XXX" is the name of the board to be added.
On the slot to which the board is to be deleted, right-click and select Delete.
Figure 1 Logical board

NOTE
If a logic board is not displayed, verify that the corresponding physical board is correctly installed.
Before deleting the board, delete the data, such as the service, clock, and protection, on the board.
Add a dual-channel ODU in the same way as adding a single-channel ODU while clicking Add MODU. A dual-channel ODU has two ports and power can only be supplied through channel 1.
a. Click OK in the displayed confirmation dialog box.
b. A dialog box is displayed again for confirmation. Click OK.
Hope it helps you!
