■ Each port has a Link LED. If it is lit, the port has a link. If the Link LED is
blinking, the port has failed its self test. The Fault and Self Test LEDs will
be blinking simultaneously.
■ If the Activity (Act) indicator LED is lit, each port LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■ If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those
ports that are operating in full duplex.
■ If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• blinking = 100 Mbps (the blinking behavior is a repeated on/off cycle
once every 0.5 sec.)
• On = 1000 Mbps
■ The Usr Mode LED is reserved for future development.
