LED Indicators
The switch's front panel contains indicators called light emitting diodes or LEDs.
LEDs make quick diagnoses on the network's status. They allow users to know, at a
glance, the kind of problem the network encounters.
Different functions of LED’s are displayed on the front panel. There are five
types of LEDs:
Power indicator:
Color : Green
Label : Power
This indicator turns to green when the switch is connected to the wall adapter. If
the green light fails to flash steadily, contact your dealer.
Link/ ACT indicator:
Color : Green
Label : Link/ACT
This indicator flahes in a steady green when the port is linking.
Color : Green blinks steadily
Label : Link/ACT
This indicator blinks steadily when transmitting data over ethernet network.
DPX / COL indicator :
Color : Green
Label : DPX / COL
When a port is functioning in full duplex mode, the indicator corresponding to
this port flashes in a steady green.
Full Duplex dedicates bandwidth from original node to designated port, switch
can reduce the chance of collision between transmittion. Rather than checking for
collision during transmittion, switch uses that portion of UTP/STP cables to transmit
data. Therefore, at any given time, it doubles the amount of information travels
through network.
Color : Green blinks steadily
Label : Collision
This indicator blinks steadily when data encounter collision during transmission.
