LED Operation
Several LEDs are visible from the front panel. These include the power (PWR),

The function of each LED is as follows:
LED Label Color (Status) Indication
PWR Green (steady) Power is ON.
(Port 1) LK Green (steady) Port 1 is receiving a valid link integrity

idle symbols for a copper port or the
presence of an optical signal for a fiber
port.
(Port 1) AT Green (blinking) Port 1 is receiving data.
(Port 2) LK Green (steady) Port 2 is receiving a valid link integrity
signal (i.e., the presence of an optical
