Root Cause


We have resolved this issue in V100R018C00SPH313.version. It is needed to upgrade the OLT

http://support.huawei.com/carrier/navi?coltype=software#col=software&from=product&detailId=PBI1-23346801&path=PBI1-7275726/PBI1-7275742/PBI1-22892584/PBI1-19904180/PBI1-21484577

This issue is caused by the information lost in EEPROM. We have done some protection on CMC, but the protection only takes effect  after reset the CMC. SO after the patch upgrade, please reset or power cycle the CMC to resolve this issue. If the issue could not be resolved after several power cycle.

Solution

Tested MA5633 R17 software devices with MA5800 (as extended-frame/centralized management mode) running V100R018C00SPH313 patch level and confirm that the MA5633 CMC operate normally ("cable rf-power downstream" commands take effect and Hardware information is shown).

The issue persists for the initially reported CMC unit MA5633 (uplink GPON ONU SFP module serial number). The board seems to be faulty.

After the RMA process was ended ( the CMC was replaced), the issue disappeared.
