ONT for the test I’ll take TP-Link GP110 with the configured mode transparent and off DHCP, well, in fact with other single-port ethernet ONT setting is similar.
Install GPON card in Huawei OLT
On the test I’ll take the H805GPFD board with 16 GPON ports and install it in OLT Huawei SmartAX MA5683T without shutting it down.
After inserting on the board, the RUN / ALM indicator flashed red and literally a minute later green.
