The switch incorporates three sets of Light-Emitting Diodes (LEDs) to indicate ethernet, switch, and port
status:
1.
Ethernet LEDs – two separate LEDs indicating the network connection status.
2.
System LEDs – four separate LEDs indicating the switch’s status.
3.
Port LEDs – two LEDs per port indicating the port’s status.
Ethernet LEDs
The Ethernet LEDs indicate the network connection status:
System LEDs
The System LEDs indicate the switch’s status, independent of the port LEDs.
Ethernet LEDs
Indication
Ethernet Activity
(green LED)
• When flashing, the ethernet port is receiving data.
• When flashing rapidly, the traffic level is high.
Ethernet Link
(green LED)
When lit, the switch is connected to an operational ethernet.
