When you select the STACK LED, the respective STACK LEDs are green when the stack ports (on the switch
rear panel) are up, and the respective Stack LEDs are amber when the ports are down. SFP+ module port
LEDs 1 and 2 on the switch show the status for stack ports 1 and 2, respectively.
If the port LEDs are green on all the switches in the stack, the stack is operating at full bandwidth. If any port
LED is not green, the stack is not operating at full bandwidth.
Console LEDs
The console LEDs show which console port is in use. If you connect a cable to a console port, the switch
automatically uses that port for console communication. If you connect two console cables, the USB console
port has priority.
