•
Unlit—10 Mbps
•
Blinking green—100 Mbps
•
Steadily green—1000 Mbps
NOTE: In 32-port EX4300 switches, when an EX-SFP-1GE-T transceiver is installed in the
port, the LED is unlit when the speed is 100 Mbps.
LED: SPD
Indicates the PoE mode. The status indicators are:
•
Steadily green—PoE is enabled on the port and a device is drawing power.
