■ The PoE+ switches have an additional mode, PoE. In PoE mode, the Link
LED indicates the PoE configuration for the port:
• On if PoE is enabled on the port
• Off if PoE is disabled on the port.
Each port has a Link LED. If it is lit, the port has a link. If the Link LED is
■
Flashing, the port has failed its self test. The Fault and Self Test LEDs will
be Flashing 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
• Flashing = 100 Mbps (the Flashing behavior is a repeated on/off cycle
once every 0.8 sec.)
• On = 1000 Mbps
