EX-series Switch—Network Port LEDs
Each network port on the front panel of an EX-series switch
has two LEDs. Figure 6Figure 12 shows the
network ports and the locations of the LEDs on the port.
Figure 6: EX-series Switch—Network
Port LEDs
The LEDs to the left
of the port opening (labeled LED 1 in Figure 6Figure 12) indicate link activity. The
LEDs to the right of the port opening (labeled LED 2 in Figure 6Figure 12) indicate the status of one
of the four port parameters. The port parameters are: administrative
status; duplex mode; PoE status; and speed.
