Port Status
100BASE-FX Ports
Each port has an array of three LEDs to show status information.
The LEDs are identified by a corresponding array of captions
located beside the LEDs on the front panel.
LNK/ACT:
The link indicator is the top LED. It is illuminated
whenever the port is connected to another
working networked device.
The LED flashes when the port is transmitting
or receiving data.

The middle LED shines whenever the switch
detects that the corresponding port is connected
to a 100BASE (100Mbps) segment.
FDX/COL:
The lower LED is illuminated when the port is
operating in full-duplex mode. When this LED is
off, the port is operating in half-duplex mode.
The LED flashes when the switch detects
packet collisions on the port.
