PLANET EPL-1000 - Manual (Page 25)

If the OLT is running normally and the ONUs register each of their LLIDs, you should see
something similar to the figure. The left hand pane shows the MAC addresses of the OLT
and the ONU’s LLIDs. Depending on the number of ONUs, LLIDs, MAC addresses etc you
may see something slightly different. If the GUI fails to connect to the OLT, check the IP
addresses of the Host PC and the management port. Make sure you can ping the IP
address assigned to the management port. Also verify that the Host and management IP
addresses match in the GUI’s Utilities -> Settings tab.
