LED Status Indicators for the System LAN Ports
You can verify network connectivity by looking at the LAN port LEDs on the back of your system.
Each LAN port has two LEDs: The left LED indicates network connectivity and traffic, while the right LED
indicates Power over Ethernet (PoE) status for connected devices.
The G7500 system has four LAN ports: one for the system’s network connection (farthest left) and three
link-local network (LLN) connections for peripheral devices.
