Abstract: A user fails to download configuration data to an OSN 1500 with an interface board of dynamic ports due to the lack of logical configurations on tributary interface boards. As a result, services may be interrupted.
Symptom
1:The download fails or partially fails. Dynamic port and service data fail to be downloaded to NEs, as shown in the following figure.


2:The download succeeds. However, the interface board becomes dimmed on the NE Panel. This is only a display issue and does not affect NMS functionality.
Before the download:


After the download:

Identification Method
The preceding symptoms occur if boards are installed in slots 6 and 7 on the OSN 1500A. (Slots 6 and 7 are used to install interface boards.)
The preceding symptoms occur if boards are installed in slots 14, 15, 16, and 17 on the OSN 1500B. (Slots 14, 15, 16, and 17 are used to install interface boards.)

1.2 [Root Cause]
For earlier versions of OSN 1500A 5.36.30.10 and earlier version of OSN 1500B 5.36.30.10: Interface boards are not applied to NEs due to incorrect logical configurations. As a result, dynamic port and service data fail to be downloaded.
For OSN 1500A 5.36.30.10 and later versions: The NMS does not apply interface boards last. Therefore, if the processing board on which interface board application depends is not added, configuration data fails to be downloaded.

1.3 [Impact and Risks]
1. NE type involved: OSN 1500
Board types affected:
N1D75S, N1D12S, N1D12B, N1MU04, N1TSB8, N1ETF8, N1EFF8, N1EU04, N1OU08, N2OU08, N1EU08, N1TSB4, N1ETS8, N1DM12, N1D34S, N1C34S, L75S, and L12S

2.Scenario 1: The download fails or partially fails. Logical boards are not downloaded to the OSN 1500. As a result, services depending on the logical boards fail to be downloaded and the download process ends.
3.Scenario 2: The download succeeds. However, logical boards are not downloaded to the OSN 1500. This does not affect services and alarm reporting but affects board display.

1.4 [Measures and Solutions]
Preventive Measure
Do not download data to an OSN 1500 with interface boards on the NMS. Use DC to back up and restore the database of the OSN 1500.
Restoration Measure
If an OSN 1500 is equipped with interface boards and the configuration data fails to be downloaded. Perform the following restoration measures:


  • If the database of the OSN 1500 has been backed up, use DC to restore the database.
  • If the database of the OSN 1500 has not been backed up, restore the download in either of the following ways:

− Install a patch to resolve this problem and download the configuration data to the OSN 1500 again.
− Change the OSN 1500 to a preconfigured NE on the U2000, record the associated services of its interface boards, delete the interface boards and associated services, then download configuration data to the OSN 1500, and add interface boards and associated services to it.
Solution
The problem has been resolved in the following NMS versions:


  • NMS versions involved for the OSN 1500A (earlier versions of 5.36.30.10) and OSN 1500B (earlier versions of 5.36.30.10):

− U2000 V100R005C00CP6032 and later
− U2000 V100R006C00CP3011 and later
− U2000 V100R006C02CP3001 and later


  • NMS versions involved for the OSN 1500A (5.36.30.10 and later):

− U2000 V100R002C01CP5035 and later
− U2000 V100R006C02SPC302 and later
