Abstract<\/strong>: A user fails to download configuration data to an Huawei\u00a0OSN<\/a> 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.<\/p>\n

Symptom<\/strong>
\n1:The download fails or partially fails. Dynamic port and service data fail to be downloaded to NEs, as shown in the following figure.<\/p>\n

 <\/p>\n

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.
\nBefore the download:<\/p>\n

After the download:<\/p>\n

Identification Method<\/strong>
\nThe 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.)
\nThe preceding symptoms occur if boards are installed in slots 14, 15, 16, and 17 on the OSN 1500B<\/a>. (Slots 14, 15, 16, and 17 are used to install interface boards.)<\/p>\n

1.2 [Root Cause]<\/strong>
\nFor 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.
\nFor 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.<\/p>\n

1.3 [Impact and Risks]<\/strong>
\n1. NE type involved: OSN 1500
\nBoard types affected:
\nN1D75S, N1D12S, N1D12B, N1MU04, N1TSB8, N1ETF8, N1EFF8, N1EU04, N1OU08, N2OU08, N1EU08, N1TSB4, N1ETS8, N1DM12, N1D34S, N1C34S, L75S, and L12S<\/p>\n

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.
\n3.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.<\/p>\n

1.4 [Measures and Solutions]<\/strong>
\nPreventive Measure
\nDo 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.
\nRestoration Measure
\nIf an OSN 1500 is equipped with interface boards and the configuration data fails to be downloaded. Perform the following restoration measures:<\/p>\n
