Port Status LEDs
TE100-S55 is equipped with six Status LEDs which reflect the
status of each port.
As you connect a network cable to the TE100-S55, it will auto-
detect the type of cable and the corresponding 10/100 LED will
light up. Likewise, depending on the port connection, the
DUPLEX LED will light up to indicate its status of full or half
duplex signaling.
When a port connection is active, the LINK LED will light up to
indicate its operative state. Also, as activities occur on the
network, the RX or TX LED will light up to indicate its
transmission or reception of data.
When multiple packets are delivered at the same time, a collision
will occur and the COL LED will light up. Although collisions
are normal, if there’s too much, you should consider rearranging
the workgroups or optimize the network for reduced traffic.
