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.
If the PoE/PoE+ indicator LED is lit, the Link and Mode LEDs indicate
PoE/PoE+/PoE+ status.
Link LED:
• On = PoE/PoE+ is enabled on this port.
• Off = PoE/PoE+ is disabled on this port.
• Slow Blinking = Internal PoE/PoE+ fault on this port. or has been
denied power.
• Fast Blinking = This port is denied PoE/PoE+ power or has an
external load fault.
Mode LED:
• On = PoE/PoE+ power is be supplied on this port.
• Off = PoE/PoE+ is not being supplied on this port.
