Precautions for changing the NE ID of an OSN 8800

7

After an NE ID is changed using the NMS, functions such as logical fiber connections, protection, and wavelength locking are not reconfigured. Do not run commands to change the NEID of an NE in the maintenance phase. If commands are executed to change the NEID, the NE and NMS configurations are not synchronized, and the recovery scheme is complex. Therefore, such an operation is forbidden.

Precautions for changing the IDs of OSN 3800/6800/8800 NEs
Pay attention to the following when changing the IDs of OSN 3800/6800/8800 NEs: Changing an NE ID is risky because it will interrupt NE communication. Before changing an NE ID, you must delete fiber connections, protection groups, and functions such as IPA and ALC from the NE. After changing the NE ID, you need to reconfigure the fiber connections and functions for the NE on the U2000. Before changing an NE ID, you must delete the manually added monitoring relationship between WMU boards and OTU boards or line boards from the NE. After changing the NE ID, you need to restore the monitoring relationship on the U2000. If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies according to the NE ID. Once the IP address of the NE is changed, the association between the NE ID and IP address is canceled automatically.

Impact of changing the NE ID of OSN 8800
The following functions will be affected if the NE ID is changed for WDM devices: the logical fiber connections (FM), automatic optical power adjustment (OPA), intelligent power adjustment (IPA), automatic level control (ALC), automatic power equilibrium (APE), wavelength locking, optical port protection, OWSP protection, OD, and OD V2.

Precautions for changing NE IDs and IP addresses on the U2000
Take the following precautions when changing an NE ID: 1. Changing an NE ID is risky because it will interrupt NE communication. 2. Before changing an NE ID, delete protection groups, fiber connections, and functions such as IPA and ALC from the NE. After changing the NE ID, restore them for the NE on the U2000. 3. Before changing an NE ID, delete the manually added monitoring relationship between the WMU board and the OTU or line board on the NE. After changing the NE ID, restore the deleted monitoring relationship on the U2000. 4. For a gateway NE, after changing its NE ID, you need to re-create fiber connections between it and other NEs and re-specify the primary gateway NE for NEs that were originally connected to this gateway NE on the U2000. 5. If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies according to the NE ID. Once the IP address of the NE is changed, the association between the NE ID and IP address is canceled automatically. Take the following precautions when changing an NE IP address: 1. Changing an NE IP address will reset the NE. 2. After changing the IP address of a gateway NE, you need to re-specify the IP address of the gateway NE in the DCN management window on the U2000, and re-specify the primary gateway NE for NEs that were originally connected to this gateway NE.

OSN 8800 NE resource grouping to OTN optical NEs
Select an optical NE. Right-click it and choose Attribute from the shortcut menu. Navigate to the Resource Division window. In the window, find the desired OptiX OSN 8800 NE from idle NEs and add the NE to the right-side box. Then click OK.

Precautions for commissioning the TN12OBU1P board of OSN 8800
The working principle of the TN12OBU1P1 board is as follows: The attenuation of the built-in VOA before the IN port on the TN12OBU1P1 board cannot be manually adjusted. The board controls the input optical power. When the sum of the input optical power on the IN port plus 20 dB (gain) is greater than 7 or 9 dBm (maximum output power of the board, depending on the version), the board software automatically increases the attenuation of the built-in VOA to ensure that the output optical power is 7 or 9 dBm. When the sum of the input optical power on the IN port plus 20 dB (gain) is less than 7 or 9 dBm (maximum output power of the board, depending on the version), the board software adjusts the attenuation of the built-in VOA to the minimum value to obtain an output optical power value that is as high as possible. The TN12OBU1P1 board is a commissioning-free board. In addition, the input optical power of the board is not locked. Instead, the gain is locked to 20 dB for the board.
