10/100TX port or an installed MII expansion port is
operating at 100Mbps speed.
Note:
These LEDs only function with ports capable of
operating at 100Mbps speed (i.e., the 10/100TX port or
an installed 10/100 MII module).
The corresponding port’s receive buffer is full
(maximum utilization).
Note:
It is normal to see these LEDs light when the
network is in a state of moderate-to-heavy activity.
Indicates full duplex mode on the corresponding port.
Indicates a collision at the switching port for those
ports operating in half duplex mode.
Note:
Full duplex means that a port can transmit and
receive at the same time.
Note:
Collision is indicated only on those ports
operating in half duplex mode.
Traffic activity is occurring on the port (transmit [TX]
or receive [RX]).
Note:
During heavy traffic periods, this LED may be lit
continuously.
A node or other network device is properly connected
to the corresponding port and is powered on.
