Watch out Wavelength Information of the TNF1X40 on the OSN 1800

Summary:

The wavelength information of the huawei dwdm TNF1X40 board is not verified at the equipment manufacturing and assembly stage. As a result, wavelength information at some ports of the board is not recorded.

[Problem Description]

Trigger conditions:

Wavelength informaion is not properly displayed when the wavelength information of the TNF1X40 board is queried.

Symptom:

Wavelength informaion of the TNF1X40 board is not properly displayed.

Identification method:

When the wavelength information of the TNF1X40 board is queried through the NMS, the wavelength information of some ports is not displayed.
For example, the wavelength information of the MD02 and MD03 ports is not displayed, as shown in the following figure.

TNF1X40 board MD02 and MD3 ports

When the wavelength information of the TNF1X40 board is queried through the Navigator, the wavelength information of some ports is displayed as 255. For example, the wavelength information of the MD02 port (optical port 3, in slot 3) is displayed as 255, as shown in the following figure.

[Root Cause]

The wavelength information of the TNF1X40 board is not verified during manufacturing tests. As a result, wavelength information at some ports of the board is not recorded.

[Impact and Risk]

Wavelength information of the TNF1X40 board cannnot be properly reported, and logical fiber connections fail to be established. Services are not affected.

[Measures and Solutions]

The recovery measures apply to the case of TNF1X40 used on the  OptiX OSN 1800 I/II Chassis, if the board need to be record is used on the OptiX OSN 1800 OADM Frame, please replace it on the Huawei OptiX OSN 1800 I/II Chassis.

Recovery measures:

Complete the following steps:

1. Record wavelength by running the :optp:$hexbid,1,83,1,13,08,$port,3,$num command, wherein Hexbid indicates the slot ID (hexadecimal) of the TNF1X40 board, Port indicates the port ID, and Num indicates the wavelength number.

Note: For information about the port ID and wavelength number used in the command, refer to Attachment 1. For example, to record the wavelength of the MD09 port of the TNF1X40 board in slot 3, run the :optp:3,1,83,1,13,08,a,3,1d command.

2. Verify the wabelength records by querying the wavelength information of each port of the huawei dwdm TNF1X40 board through the NMS and comparing the queried information with the standard wavelength information in Attachment 2.

Workarounds:

None.

Preventive measures:

On March 15th, 2013, the manufacturing and assembly department updated the software version for testing and added wavelength recording into the updated version.
