Switch Installation Guide
The RJ-45 ports have two LEDs, one for Link and one for activity (Mode status for non PoE and Load status for
PoE). The LED indications are described in the following table:
10/100/1000 Base-T/Combo Ethernet RJ-45 Port LEDs
The following figure illustrates the 10/100/1000 Base-T/Combo Ethernet RJ-45 port LEDs.
